    U.S. to Press China to Stop Flow of Fentanyl

    President Biden pressed the Chinese leader Xi Jinping on Wednesday to crack down on the Chinese firms that are helping to produce fentanyl, a potent drug that has killed hundreds of thousands of Americans.A plan to curb China’s illicit exports of fentanyl and, particularly, the chemicals that can be combined to make the drug was hoped to be one of the more significant achievements for the United States out of Mr. Biden and Mr. Xi’s meeting, which took place as leaders from Pacific nations gathered for an international conference in San Francisco.A summary of the meeting published by China’s CCTV News said that Mr. Biden and Mr. Xi had agreed to establish an anti-drug working group.China is home to a thriving chemical industry that pumps out compounds that are made into pharmaceuticals, fragrances, textile dyes and fertilizers. Some of those same compounds can also be combined to create fentanyl, an opioid that can be 100 times as potent as morphine.U.S. officials argue that this vast chemical industry is playing a key role in the American fentanyl crisis by supplying the bulk of materials used in illegal drug labs, including in Mexico, which is now the largest exporter of fentanyl to the United States.The Chinese government denies that its country plays such a pivotal role and instead blames the United States for harboring a culture of drug use.“All-out marketing by pharmaceutical companies, over-prescription by doctors, ineffective government crackdowns and the negative implications of marijuana legalization are among the combination of factors behind an ever-growing market for narcotics,” China’s foreign ministry said in a statement last year.U.S. officials say they have stopped more fentanyl from coming into the United States in the past two years than in the previous five years combined. According to the Centers for Disease Control and Prevention, fentanyl and other synthetic opioids may have resulted in more than 77,000 overdose deaths in the United States between May 2022 and April 2023. The problem with fentanyl overdoses is particularly acute in San Francisco, where Mr. Biden and Mr. Xi are meeting.Ian Johnson, a senior fellow for China studies at the Council on Foreign Relations, said that getting China to agree to do something about fentanyl would resonate more with average Americans than the typical “deliverables” from international meetings.“For Biden, that would be nice to have to show to the heartland of the United States that relations with China are more than just some esoteric matter, but can actually bring something to ordinary people,” Mr. Johnson said in a briefing held by the council last week. Republicans have made fentanyl-related deaths a central piece of their campaign against Mr. Biden and Democrats in the 2024 elections.Red stained pollen grain sample at the U.S. Customs and Border Protection in Chicago, last year.Lyndon French for The New York TimesCollecting pollen samples at a Customs and Border Protection facility. The extent to which an agreement with China would curb the flow of fentanyl into the United States is unclear.Lyndon French for The New York TimesStill, given the difficulties with policing an illicit industry, the extent to which an agreement would curb the flow of fentanyl into the United States is unclear.Roselyn Hsueh, an associate professor of political science at Temple University, said that an agreement between Mr. Biden and Mr. Xi could lead the Chinese central government to provide more oversight and invest more resources into inspection and monitoring. But she said Beijing had run into difficulty in the past clamping down on fentanyl and precursor chemicals.Before 2019, China was the primary source of fentanyl coming into the United States, typically through the mail and other commercial couriers. As a part of trade talks with President Donald J. Trump, the Chinese government in 2019 agreed to prohibit the production, sale and export of all fentanyl-related drugs except through special licenses.But that resulted in Chinese companies rerouting to Mexico and India’s emergence as a new production site, Ms. Hsueh said. The main source of U.S. fentanyl became Mexican criminal organizations, which used Chinese-made components and Chinese money-laundering services.Today, online sales that mask the identities of sellers and buyers further complicate enforcement. The regulation and enforcement of fentanyl and precursor chemicals remain “fragmented and decentralized” among Chinese local governments, industry associations and firms with vested interests in the chemical trade, Ms. Hsueh said.U.S. officials have said that problem is compounded because many of the ingredients used to make fentanyl are legal chemicals that can be used for legitimate purposes in other industries. The United States has issued sanctions against dozens of people in China and Hong Kong for their role in fentanyl trafficking. In September, Mr. Biden added China to the U.S. list of the world’s major drug-producing countries, a move that the Chinese government denounced as “a malicious smear.”Last month, the U.S. customs department released an updated strategy to combat fentanyl and synthetic drugs, including through the enhanced use of data and counterintelligence operations to track drug manufacturing and distribution networks, and target suspicious locations and recipients that demonstrate patterns of illicit activity. “In my 30 years as a customs official, the trafficking of synthetic illicit drugs like fentanyl is one of the toughest, most daunting challenges I have ever seen,” said Troy Miller, the acting commissioner for Customs and Border Protection.U.S. officials say they have stopped more fentanyl from coming into the United States in the past two years than in the previous five years combined.Mamta Popat/Arizona Daily Star, via Associated PressU.S. officials believe China’s dominance as a chemical producer makes Beijing’s cooperation key for enforcement. Administration officials, including Commerce Secretary Gina M. Raimondo, have raised the issue with top Chinese officials during recent trips to China.When six lawmakers, including Senator Chuck Schumer, the majority leader, had a chance to talk to Mr. Xi during a visit to China last month, the main issue they brought up was not trade or military coordination or climate change, but the harm that fentanyl had caused in their home states.“Everyone told stories, personal stories about how, you know, friends of ours, family, have died from fentanyl, and how this was a really important issue, and I think that you could tell that made an impression on him, how deeply we felt about it,” said Mr. Schumer, a New York Democrat.Fentanyl precursors from China have become a bipartisan issue in Congress, and the six senators who spoke with Mr. Xi were three Democrats and three Republicans.“China needs to enforce laws that prevent the export of fentanyl precursors to international drug markets,” said Senator Bill Cassidy, Republican of Louisiana.Despite the scale of the problem, there is hope that greater coordination between the United States and China could improve the situation. Cooperation between the countries on preventing shipments of the precursor chemicals stalled several years ago after the United States placed sanctions on a Chinese government entity for its alleged involvement in human rights abuses in China’s westernmost region, Xinjiang.That entity was located at the same address in Beijing as the National Narcotics Laboratory of China, which plays a key role in China’s law enforcement effort on drug-related chemicals.Chinese officials deeply resent American sanctions on their institutions, and U.S. officials have taken the position that because of the risk of confusion among the two institutes at the same address, neither institute can work with the United States.China then broadened its position in August 2022 when it halted any counternarcotics coordination with the United States as one of a series of measures taken in response to a visit to Taiwan by Representative Nancy Pelosi, then the speaker of the House.

    Xi Jinping to Address U.S. Business Leaders Amid Rising Skepticism of China Ties

    Corporate executives will pay $2,000 a head to dine with China’s leader in San Francisco next week, in one of a series of engagements aimed at stabilizing the U.S.-China relationship.The Chinese leader Xi Jinping, who is set to meet with President Biden in San Francisco next week, is expected to speak to top American business executives at a dinner following that bilateral meeting.Mr. Xi, who is traveling to the United States for an international conference, will address business leaders at a challenging moment in U.S.-China relations. The United States has expressed growing concern about China’s military ambitions and has sought to cut off Beijing’s access to technology that could be used against the United States. China’s treatment of Western companies, which are facing tougher restrictions in how they do business, have also prompted firms to question the wisdom of investing in China.Still, Chinese and American leaders have expressed interest in bolstering ties between their economies, the world’s two largest, which remain inextricably linked through trade. The Biden administration has sent several top officials to China this year to try to make clear that while the United States wants to protect national security, it does not seek to sever economic ties with Beijing.It is unclear whether Mr. Xi’s visit will do much to alleviate the skepticism of foreign businesses, many of which are deterred both by China’s slowing economic growth and the tighter grip of the Chinese Communist Party on business activity under Mr. Xi.Tickets to the dinner and reception, hosted by the National Committee on U.S.-China Relations and the U.S.-China Business Council, cost $2,000 each, according to an invitation circulating online. For $40,000, companies can purchase eight seats at a table plus one seat at Mr. Xi’s table, a person familiar with the event said.Engagements between Chinese officials and the U.S. business sector will try to send the signal that China remains an attractive place to do business, “as evidenced by these companies flocking to meet with Xi Jinping and have dinner with him,” Jude Blanchette, the Freeman Chair in China Studies at the Center for Strategic and International Studies, said in a briefing on Tuesday.Beijing wants this for “tactical reasons,” Mr. Blanchette said. “I don’t think, at a broad level, they’re expecting or see the prospect of resetting or recalibrating the relationship.”Foreign firms are particularly concerned about Chinese regulations that block them from selling to the government or into certain markets, and a broader counter-espionage law that can lead to prison time for company executives and researchers who deal in sensitive industries. At the same time, the United States is stepping up restrictions on investing and selling advanced technology to China, saying that such ties can pose national security concerns.Many businesses still see China as an essential market, but an increasing number are starting to look to other countries for their new investments. A survey by the U.S.-China Business Council of its members this year found that 34 percent had stopped or reduced planned investment in China over the past year, a higher percentage than in previous years.Mr. Blanchette said Chinese officials would also see the meeting as an opportunity to try to shift the U.S. trajectory on the technology controls it has placed on China. But the United States is unlikely to change its stance, he said.“I think this will be one of the issues where the U.S. and China will have longstanding tensions. And I’m sure this will be communicated to Beijing,” Mr. Blanchette said.The visit will be Mr. Xi’s first trip to the United States since 2017, when he met with President Donald J. Trump at the Mar-a-Lago estate in Florida. Since then, U.S.-China business relations have changed drastically, with the countries carrying out a trade war and sparring over advanced technology and geopolitical influence, and China turning notably more authoritarian under Mr. Xi.The dinner and reception featuring Mr. Xi will be part of a two-day “C.E.O. Summit” taking place next week on the sidelines of a bigger meeting of the leaders of the Asia Pacific Economic Cooperation, a group of 21 countries that ring the Pacific Ocean. Mr. Biden is expected to meet with Mr. Xi earlier next Wednesday, in their first face-to-face meeting in a year.Mr. Biden and Mr. Xi are expected to discuss business and technology ties, as well as issues like communication between the countries’ militaries, stopping the flow of fentanyl to the United States and new agreements for governing artificial intelligence.In recent weeks high-level Chinese officials have met with U.S. counterparts to lay the groundwork for the trip. In a news release Wednesday, the organizers of the C.E.O. summit said that Mr. Biden and Mr. Xi would be in attendance at the two-day summit, along with other world leaders and the chief executives of companies including Microsoft, Mastercard and Pfizer.

    Janet Yellen, U.S. Treasury Secretary, Will Meet With Chinese Counterpart

    The high-level meetings in San Francisco will lay the groundwork for talks between President Biden and China’s top leader, Xi Jinping.Treasury Secretary Janet L. Yellen will hold two days of high-level meetings with her Chinese counterpart, Vice Premier He Lifeng, this week, as the United States and China look to build upon an effort that started earlier this year to improve communication between the world’s two largest economies.The meetings will take place on Thursday and Friday in San Francisco ahead of the Asia-Pacific Economic Cooperation summit, which begins on Saturday. The meetings will help lay the groundwork for expected talks at the summit between President Biden and China’s top leader, Xi Jinping. The Treasury Department said that the United States hoped Ms. Yellen’s meetings would “further stabilize the bilateral economic relationship” and make progress on key economic issues.The revival of economic diplomacy between the two countries comes at a fraught moment for the global economy, which is grappling with sluggish output and wars in Ukraine and the Middle East.A senior Treasury Department official said the Biden administration continued to seek a better understanding of China’s economic policies. Ms. Yellen is expected to talk to Mr. He about issues like debt relief for developing countries and the financing of international efforts to combat climate change. The discussions are also intended to address any misunderstandings from recent national security actions that the Biden administration has taken, such as restrictions on investments that Americans can make in Chinese industries.The talks in San Francisco follow Ms. Yellen’s trip to Beijing in July. After that visit, the Treasury Department established financial and economic working groups to promote more regular dialogue between the United States and China.As Treasury secretary, Ms. Yellen has been trying to help the United States diversify its supply chains so that it relies more on allies and domestic production and less on China, which over the past decade has similarly worked to become less reliant on imports.In a speech at the Asia Society last week, Ms. Yellen said that the United States would continue to respond to China’s economic practices while seeking ways to work together where possible. But she also made clear that she opposed efforts to sever economic ties with China.“A full separation of our economies, or an approach in which countries including those in the Indo-Pacific are forced to take sides, would have significant negative global repercussions,” Ms. Yellen said. “We have no interest in such a divided world and its disastrous effects.” More

    Biden Describes China as a Time Bomb Over Economic Problems

    The sharply worded comments are the latest example of the president’s willingness to criticize China even as he tries to ease tensions.President Biden warned on Thursday that China’s struggles with high unemployment and an aging work force make the country a “ticking time bomb” at the heart of the world economy and a potential threat to other nations.“When bad folks have problems, they do bad things,” the president told a group of donors at a fund-raiser in Park City, Utah.Mr. Biden’s comments are the latest example of the president’s willingness to criticize China — often during fund-raising events with contributors to his presidential campaign — even as his administration seeks to ease tensions between the world’s two largest economies.Earlier this summer, at a fund-raiser in California, Mr. Biden called President Xi Jinping of China a “dictator” who had been kept in the dark by his own officials about the spy balloon that flew over much of the United States from late January to early February before being shot down by the U.S. military.On Thursday night, Mr. Biden said he was trying to make sure the United States has a “rational relationship with China,” but he signaled that he continues to view Beijing as America’s biggest economic competitor.“I don’t want to hurt China, but I’m watching,” Mr. Biden said in Utah.The remarks underscore the complicated diplomacy that the president and his administration are engaged in as they attempt to ease tensions with China while limiting the economic and military threats posed by the country and its Communist leadership.Relations between the two countries grew icy after the spy balloon incident and the more recent discovery that China has been inserting malicious computer code deep inside the networks controlling power grids, communications systems and water supplies around U.S. military bases.Mr. Biden has said he seeks “competition, not conflict” with China, taking steps to minimize the possibility of direct military clashes with Beijing over the South China Sea and the future of Taiwan.Top American officials have visited in recent weeks with their counterparts in China. Gina Raimondo, the commerce secretary, is expected to go there in coming weeks.But the president has moved aggressively to contain China’s rise and to restrict its ability to benefit militarily from the use of technologies developed in the United States.Mr. Biden signed an executive order this week banning American investment in some Chinese technology industries that could be used to enhance Beijing’s military capabilities. In response, the Chinese government hinted that it would retaliate and accused the United States of trying to “politicize and weaponize trade.”The president’s comments on Thursday could complicate efforts by both countries to schedule a face-to-face meeting between the two leaders in the coming months. Mr. Biden and Mr. Xi have not met in person since last November, during the Group of 20 summit of world leaders in Indonesia.The White House has not said whether the two men will have an in-person meeting at the Asia-Pacific Economic Cooperation summit, which is scheduled for later this year in San Francisco. Mr. Xi is expected to attend. More

    Yellen’s China Visit Aims to Ease Tensions Amid Deep Divisions

    Mutual skepticism between the United States and China over a wide range of economic and security issues has festered in recent years.The last time a U.S. Treasury secretary visited China, Washington and Beijing were locked in a trade war, the Trump administration was preparing to label China a currency manipulator, and fraying relations between the two countries were roiling global markets.Four years later, as Treasury Secretary Janet L. Yellen prepares to arrive in Beijing, many of the economic policy concerns that have been festering between the United States and China remain — or have even intensified — despite the Biden administration’s less antagonistic tone.The tariffs that President Donald J. Trump imposed on Chinese goods are still in effect. President Biden has been working to restrict China’s access to critical technology such as semiconductors. And new restrictions curbing American investment in China are looming.Treasury Department officials have downplayed expectations for major breakthroughs on Ms. Yellen’s four-day trip, which begins when she arrives in Beijing on Thursday. They suggest instead that her meetings with senior Chinese officials are intended to improve communication between the world’s two largest economies. But tensions between United States and China remain high, and conversations between Ms. Yellen and her counterparts are likely to be difficult. She met in Washington with Xie Feng, China’s ambassador, on Monday, and the two officials had a “frank and productive discussion,” according to the Treasury.Here are some of the most contentious issues that have sown divisions between the United States and China.Technology and trade controlsChinese officials are still smarting at the Biden administration’s 2022 decision to place significant limitations on the kinds of advanced semiconductors and chip-making machinery that can be sent to China. Those limits have hampered China’s efforts to develop artificial intelligence and other kinds of advanced computing that are expected to help power each country’s economy and military going forward.The government of the Netherlands, which is home to semiconductor machinery maker ASML, on Friday announced new restrictions on machinery exports to China. On Monday, China placed restrictions on exports of germanium and gallium, two metals used to make chips.The Biden administration is mulling further controls on advanced chips and on American investment into cutting-edge Chinese technology.Semiconductors have always been one of the biggest and most valuable categories of U.S. exports to China, and while the Chinese government is investing heavily in its domestic capacity, it remains many years behind the United States.The Biden administration’s subsidy program to strengthen the U.S. semiconductor industry has also rankled Chinese officials, especially since it includes restrictions on investing in China. Companies that accept U.S. government money to build new chip facilities in the United States are forbidden to make new, high-tech investments in China. And while Chinese officials — and some American manufacturers — were hopeful that the Biden administration would lift tariffs on hundreds of billions of dollars of Chinese imports, that does not seem to be in the offing. While Ms. Yellen has questioned the efficacy of tariffs, other top officials within the administration see the levies as helpful for encouraging supply chains to move out of China.The administration is employing both carrots and sticks to carry out a policy of “de-risking” or “friend-shoring” — that is, enticing supply chains for crucial products like electric vehicle batteries, semiconductors and solar panels out of China.President Biden during a visit to a Taiwan Semiconductor Manufacturing Company plant under construction in Phoenix. The Biden administration’s efforts to assist the U.S. semiconductor industry has rankled Chinese officials.T.J. Kirkpatrick for The New York TimesDeteriorating business environmentsCompanies doing business in China are increasingly worried about attracting negative attention from the government. The most recent target was Micron Technology, a U.S. memory chip maker that failed a Chinese security review in May. The move could cut Micron off from selling to Chinese companies that operate key infrastructure, putting roughly an eighth of the company’s global revenue at risk. In recent months, consulting and advisory firms in China with foreign ties have faced a crackdown.American officials are growing more concerned with the Chinese government’s use of economic coercion against countries like Lithuania and Australia, and they are working with European officials and other governments to coordinate their responses.Businesses are also alarmed by China’s ever-tightening national security laws, which include a stringent counterespionage law that took effect on Saturday. Foreign businesses in China are reassessing their activities and the market information they gather because the law is vague about what is prohibited. “We think this is very ill advised, and we’ve made that point to several members of the government here,” said R. Nicholas Burns, the U.S. ambassador to China, in an interview in Beijing.In the United States, companies with ties to China, like the social media app TikTok, the shopping app Temu and the clothing retailer Shein, are facing increasing scrutiny over their labor practices, their use of American customer data and the ways they import products into the United States.CurrencyChina’s currency, the renminbi, has often been a source of concern for American officials, who have at times accused Beijing of artificially weakening its currency to make its products cheaper to sell abroad.The renminbi’s recent weakness may pose the most difficult issue for Ms. Yellen. The currency is down more than 7 percent against the dollar in the past 12 months and down nearly 13 percent against the euro. That decline makes China’s exports more competitive in the United States. China’s trade surplus in manufactured goods already represents a tenth of the entire economy’s output.The renminbi is not alone in falling against the dollar lately — the Japanese yen has tumbled for various reasons, including rising interest rates in the United States as the Federal Reserve tries to tamp down inflation.Chinese economists have blamed that factor for the renminbi’s weakness as well. Zhan Yubo, a senior economist at the Shanghai Academy of Social Sciences, said the decline in the renminbi was the direct result of the Fed’s recent increases in interest rates.At the same time, China has been cutting interest rates to help its flagging economy. The interest rate that banks charge one another for overnight loans — a benchmark that tends to influence all other interest rates — is now a little over 5 percent in New York and barely 1 percent in Shanghai. That reverses a longstanding pattern in which interest rates were usually higher in China.The Fed’s rate increases have made it more attractive for companies and households to send money out of China and invest it in the United States, in defiance of Beijing’s stringent limits on overseas money movements.China pledged as part of the Phase 1 trade agreement with the United States three years ago not to seek an advantage in trade by pushing down the value of its currency. But the Biden administration’s options may be limited if China lets its currency weaken anyway.Global debtChina has provided more than $500 billion to developing countries through its lending program, making it one of the world’s largest creditors. Many of those borrowers, including several African nations, have struggled economically since the pandemic and face the possibility of defaulting on their debt payments.The United States, along with other Western nations, has been pressing China to allow some of those countries to restructure their debt and reduce the amount that they owe. But for more than two years, China has insisted that other creditors and multilateral lenders absorb financial losses as part of any restructuring, bogging down the loan relief process and threatening to push millions of people in developing countries deeper into poverty.In June, international creditors including China agreed to a debt relief plan with Zambia that would provide a grace period on its interest payments and extend the dates when its loans are due. The arrangement did not require that the World Bank or International Monetary Fund write off any debts, offering global policymakers like Ms. Yellen hope for similar debt restructuring in poorer countries.Human rights and national security issuesTensions over national security and human rights have created an atmosphere of mutual distrust and spilled over into economic relations. The flight of a Chinese surveillance balloon across the United States this year deeply unsettled the American public, and members of Congress have been pressing the administration to reveal more of what it knows about the balloon. Mr. Biden’s recent labeling of China’s leader, Xi Jinping, as a “dictator” also rankled Chinese officials and state-run media.American officials continue to be concerned about China’s human rights violations, including the suppression of the democracy movement in Hong Kong and the detention of mainly Muslim ethnic minorities in the Xinjiang region of northwestern China. A senior Treasury Department official, speaking on the condition of anonymity before Ms. Yellen’s trip, said the United States had no intention of shying away from its views on human rights during the meetings in China.Chinese officials continue to protest the various sanctions that the United States has issued against Chinese companies, organizations and individuals for national security threats and human rights violations — including sanctions against Li Shangfu, China’s defense minister. The Chinese government has cited those sanctions as a reason for its rejection of high-level military dialogues. More

    China’s Extreme Floods and Heat Ravage Farms and Kill Animals

    China’s leader has made it a national priority to ensure the country can feed its large population. But weather shocks have disrupted wheat harvests and threatened pig and fish farming.The downpour began in late May, drenching the wheat crops in central China. As kernels of wheat blackened in the rain, becoming unfit for human consumption, the government mobilized emergency teams to salvage as much of the harvest as possible. In a viral video, a 79-year-old farmer in Henan Province wiped away tears as he surveyed the damage.The unusually heavy rainfall, which local officials said was the worst disruption to the wheat harvest in a decade, underscored the risks that climate shocks pose to President Xi Jinping’s push for China to become more self-reliant in its food supply.Ensuring China’s ability to feed 1.4 billion people is a key piece of Mr. Xi’s goal of leading the country to superpower status. In recent years, tensions with the United States, the coronavirus pandemic and Russia’s war on Ukraine have all created more volatility in global food prices, heightening the urgency for China to grow more of its own crops.The country has not experienced food price inflation at the levels seen in other major economies, but officials are concerned about the vulnerability of its food supply to global shocks. Last summer, prices for pork, fruit and vegetables spiked in China, prompting the government to release pork from its strategic reserves to stabilize prices. Afterward, Chinese leaders reiterated their call to prioritize food security.In recent weeks, extreme heat has killed fish in rice paddies in southern China’s Guangxi Province and thousands of pigs at a farm in the eastern city of Nantong, according to local news reports. The fire department in the northeastern city of Tianjin was called in to spray water on pigs that were suffering heat strokes while riding in a truck. Officials have warned about extreme heat and flooding damaging wheat crops in the northwestern region of Xinjiang.In a country where famines have destabilized dynasties throughout history, the ruling Communist Party is also aware that fulfilling basic needs is a prerequisite for political stability.Harvesting wheat in early June in Zhumadian, Henan Province, China.Josh Arslan/ReutersLast year, food shortages became a potent source of unrest after the government imposed a draconian lockdown on Shanghai, a city of 25 million people, to control the spread of the coronavirus. Online videos showed fighting among residents in the streets and in grocery stores to grab food. In the nationwide protests that ensued against China’s “zero Covid” policies, protesters shouted, “We want food, not Covid tests.” Already, farmland in China is shrinking, as rapid urbanization has polluted large swaths of the country’s soil and governments have sold rural land to developers. The distribution of water between northern and southern China is uneven, leaving some crop-growing regions vulnerable to droughts and others to flooding. The war in Ukraine has threatened China’s access to wheat and fertilizers. And a trade war with the United States that began in 2018 made it more expensive for China to buy soybeans and other foods from America.Mr. Xi has depicted self-reliance in food as a matter of national security, often saying, “Chinese people should hold their rice bowls firmly in their own hands.” He has set a “red line” that the country must maintain 120 million hectares of farmland, and has declared war on food waste, especially in restaurants. The Chinese government frequently points out that it has to feed one-fifth of the world’s population with less than 10 percent of the world’s arable land.Farmers spreading fertilizer in a recently harvested wheat field, now newly planted with corn, in Luohe, Henan Province, this month.Qilai Shen for The New York TimesTo create a more stable food supply, China has stockpiled crops and purchased more farmland overseas. It has been developing heat-resistant rice strains, genetically modified soybeans and new seed technologies, an effort that has triggered accusations of intellectual property theft from the United States.An article on the front page of the People’s Daily newspaper on Monday said Mr. Xi had a “special affection” for farmers and prioritized increasing their incomes. Last month, he visited a wheat field in northern China’s Hebei Province, where farmers were attempting to boost grain production by growing wheat varieties that could withstand drought.In a state-produced video of Mr. Xi’s visit, local officials showed off the breads and noodles that could be made with the new wheat varieties. “President Xi hopes that we can lead a happier life,” a local farmer said in the video, “and we will work harder toward that goal.”But weather-related shocks to the food supply are a far more unpredictable challenge.“You can impose more regulations to dis-incentivize local governments from selling farmland. You can subsidize farmers,” said Zongyuan Zoe Liu, a fellow for international political economy at the Council on Foreign Relations, a U.S.-based research institute. “But when extreme weather conditions happen, it not only creates damage, but it’s also very expensive to fix.”This month, record rainfall flooded the city of Beihai in southern China. And parts of China, including major cities like Shanghai and Beijing, have already experienced unusually early heat waves this year, with temperatures this month exceeding 106 degrees Fahrenheit in some areas.But the most recent fears about food security stemmed from the flooding in Henan Province and the surrounding regions in central China, which produce more than three-quarters of the country’s wheat.A farmer planting soy beans in a recently harvested wheat field in Luohe on Wednesday.Qilai Shen for The New York Times“During harvest season, the thing wheat farmers fear the most is long-lasting rains,” said Zhang Hongzhou, a research fellow who studies China’s food strategy at Nanyang Technological University in Singapore. “This is happening at the worst time.”The rains hit just as farmers were preparing to begin this year’s harvest, causing some of the wheat to sprout. This lower-quality wheat is unsuitable to process into flour and is typically sold at a lower price as animal feed.The extent of the damage to this year’s crop is still unclear. A lower wheat yield could force China to import more wheat this year and raise global grain prices, analysts said.China is the world’s largest producer and consumer of wheat. Demand has risen along with incomes as people in cities buy more Western-style breads and desserts. Soaring meat consumption in China has also necessitated more wheat, which is used for animal feed.In response to the rainfall in Henan, the Chinese government authorized 200 million yuan, or about $28 million, in disaster relief to help dry the wet grains and drain the soaked fields. Rural officials set up a 24-hour hotline for farmers and urged local governments to find corporate buyers for damaged wheat that is still edible.A farmer watering a recently harvested wheat field in Luohe.Qilai Shen for The New York TimesState media outlets have said the government’s efforts minimized losses for farmers, with a front-page article in a recent People’s Daily newspaper trumpeting the progress of the harvest. CCTV, the state broadcaster, aired a 15-minute video segment showing government officials warning farmers to harvest early.China’s fixation on food security has global implications, in large part because it maintains huge stockpiles of food, including what the U.S. Department of Agriculture estimates is about half of the world’s wheat reserves. Last year, U.S. officials accused China of hoarding food stocks and causing global food prices to rise, particularly in poorer countries. In response, China blamed the United States for instigating a global food crisis, saying American sanctions against Russia were hurting wheat exports to African countries.Gauging the stability of China’s food supply is difficult because information about the exact quantity and quality of its crop stockpiles is treated like a state secret. Although the country’s official data regularly shows record high wheat output, for instance, analysts have questioned the reliability of the data.But in January 2022, the government offered a rare glimpse. In response to the accusations by Western countries that China was hoarding food, a commentary published in The Economic Daily, a state-controlled newspaper, revealed that China had enough wheat and rice reserves to feed its people for at least 18 months, which the article suggested was a reasonable amount of stockpiling.“To be prepared for unexpected incidents is a principle of governing a nation,” the commentary said.Farmers planting soy beans in Luohe.
