Industry players should not make up false information on supply levels and costs that could heat up the market, the National Development and Reform Commission (NDRC) added in its statement.
The NDRC said it was setting out what it considered as price-pushing behaviours to maintain market order.
China has been trying to rein in controls amid surging commodity prices and looking into setting up a price index of products such as coal and iron ore.
Any significant rises in coal prices without a good reason would not be allowed, the NDRC added.
A “substantial price increase” would be any medium-to-long term contract coal sales prices higher than the upper range of government requirement, or spot prices rising more than 50% of the limit.
China said on Thursday it was exempting all types of coal from import tariffs from May till the end of March 2023.
