Chinese officials are quietly drawing up a “whitelist” of critical U.S. goods that importers rely on to exempt them from Beijing’s retaliatory tariffs, Reuters reported, citing unnamed people familiar with the matter.

The news adds to a growing number of reports from China of businesses discovering that tariffs have been waived on some goods, such as certain semiconductor and integrated circuit products.

Precisely which goods are on the new whitelist is not publicly known, but Reuters reported that Chinese authorities had privately contacted businesses to alert them of the relevant waivers.

China has said it is open to dialogue on trade but accused the U.S. of bullying, and said that it is willing to fight to the end.

U.S. President Donald Trump said he and his administration are engaged in talks with China—which Beijing has denied—and that he believes they will eventually make a deal on trade.

Trump has hit China with a 125 percent tariff, plus an additional 20 percent related to its role in the fentanyl trade, on top of other existing tariffs.

China has responded with a 125 percent tariff on U.S. goods, among other countermeasures on trade.
