US slams China for backpedaling and says tariffs will go up

SHANGHAI/BEIJING/NEW YORK -- The lead U.S. trade negotiator said Monday that the Chinese delegation had reneged on early promises over the past week and that tariffs on more imports from China will be raised to 25% from 10% on Friday.

The about-face by China is "unacceptable," U.S. Trade Representative Robert Lighthizer told reporters in Washington.
