Reuters, BEIJINGBeijing is insisting US tariffs must be rolled back as part of any phase one trade deal with Washington, the Global Times newspaper said yesterday, citing unnamed sources, amid continued uncertainty on whether the two sides can strike a deal. “A US pledge to scrap tariffs scheduled for December 15 cannot replace the rollbacks of tariffs,” the newspaper said in a tweet, referring to an additional round of tariffs on Chinese imports to be implemented in the absence of a trade deal. The Global Times is published by the People’s Daily, the official newspaper of the Chinese Communist Party. Top trade negotiators for both countries also spoke again and agreed to continue working on the remaining issues. US Senate Finance Committee Chairman Chuck Grassley told reporters on Tuesday that Beijing invited US Trade Representative Robert Lighthizer and Secretary of the Treasury Steven Mnuchin for in-person talks in Beijing.
