The lead U.S. negotiator in trade talks with China cheered “a great deal of productivity” in resolving differences between the world’s two leading economic powers, after officials wrapped two days of bargaining in Switzerland following President Donald Trump imposing steep tariffs and Beijing retaliating.

Newsweek has contacted the White House and the Chinese Foreign Ministry for comment. President Donald Trump raised U.S. tariffs on China to a combined 145 percent, prompting the Chinese to retaliate with a 125 percent levy on American imports.

The president said reducing tariffs to 80 percent from the current 145 percent “sounds right,” as U.S. and Chinese negotiators prepare to meet in Switzerland.
