Beijing is going on an international charm campaign to coax other countries hit hard by “Liberation Day” tariffs to take on the U.S.

China has exempted some U.S. imports from its 125% tariffs and is asking firms to identify critical goods they need levy-free, according to businesses notified, in the clearest sign yet of Beijing's concerns about the trade war's economic fallout.

Levies on certain U.S.-made microchips have been dropped, importers say. Meanwhile, China denied President Trump’s claims that talks to reduce tariffs are happening.
