China has prepared powerful countermeasures to retaliate against US companies if president-elect Donald Trump reignites a smouldering trade war between the world’s two biggest economies, according to Beijing advisers and international risk analysts.Chinese leader Xi Jinping’s government was caught off-guard by Trump’s 2016 election victory and the subsequent imposition of higher tariffs, tighter controls over investments and sanctions on Chinese companies.But while China’s fragile economic outlook has since made it more vulnerable to US pressure, Beijing has introduced sweeping new laws over the past eight years that allow it to blacklist foreign companies, impose its own sanctions and cut American access to crucial supply chains. “This is a two-way process. China will of course try to engage with President Trump in whatever way, try to negotiate,” said Wang Dong, executive director of Peking University’s Institute for Global Cooperation and Understanding. “But if, as happened in 2018, nothing can be achieved through talks and we have to fight, we will resolutely defend China’s rights and interests.” President Joe Biden maintained most of his predecessor’s measures against China, but Trump has already signalled an even tougher stance by appointing China hawks to important roles.China now has at its disposal an “anti-foreign sanctions law” that allows it to counter measures taken by other countries and an “unreliable entity list” for foreign companies that it deems to have undermined its national interests. An expanded export control law means Beijing can also weaponise its global dominance of the supply of dozens of resources such as rare earths and lithium that are crucial to modern technologies.Some content could not load.

These included sanctions imposed on Skydio, the biggest US drone maker and a supplier to Ukraine’s military, that ban Chinese groups from providing the company with critical components. Beijing has also threatened to include PVH, whose brands include Calvin Klein and Tommy Hilfiger, on its “unreliables list”, a move that could cut the clothing company’s access to the huge Chinese market. “This is the tip of the iceberg,” Gilholm said, adding: “I keep telling our clients: ‘You think you’ve priced-in geopolitical risk and US-China trade warfare, but you haven’t, because China hasn’t seriously retaliated yet’.”China is also racing to make its technology and resource supply chains more resistant to disruption from US sanctions while expanding trade with countries less aligned to Washington.From Beijing’s perspective, while relations with the US were more stable towards the end of Biden’s presidency, the outgoing administration’s policies had largely continued in the same vein as in Trump’s first term. “Everyone was already expecting the worst, so there won’t be any surprises. Everybody is ready,” said Wang Chong, a foreign policy expert at Zhejiang International Studies University.Some content could not load.
