By sending Vice Premier Liu He to Washington just 24 hours before President Trump’s threat to raise China tariffs to 25% goes into effect, China is signaling that it wants to get a trade deal finished, trade policy analysts say.

“We’ve never seen this kind of pressure tactic being applied to China, but I would say so far it seems to be working,” said Welles Orr, a former assistant trade representative during the George H.W. Bush administration, now with the law firm Miller and Chevalier. “On Monday, I expected to hear that Liu He was not going to be making the trip. But the fact that he is coming suggests he is coming to make a deal.”
