The Trump administration is considering more than doubling its planned tariffs on $200 billion in Chinese imports, ratcheting up pressure on Beijing to return to the negotiating table, three people familiar with the internal deliberations said.

The U.S. imposed 25 percent tariffs on $34 billion of Chinese products in early July, and the review period on another $16 billion of imports ended July 31. President Donald Trump had threatened an additional $200 billion with levies of 10 percent, a level the administration may raise to 25 percent in a Federal Register notice in coming days, one of the people said.

At the same time, representatives of U.S. Treasury Secretary Steven Mnuchin and Chinese Vice Premier Liu He are having private conversations as they look for ways to reengage in negotiations, according to people who spoke about the deliberations on condition of anonymity.
