The United States may lift tariffs on imports of Chinese goods, while leaving others in force as part of an enforcement mechanism on a trade agreements between the US and China, said White House economic adviser Larry Kudlow, Reuters reported.

“We have to see what the track record is and we’re not going to give up our leverage. However, just to clarify, that doesn’t necessarily mean all the tariffs will be kept in place. Some of the tariffs would be kept there,” Kudlow said.

US Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin arrived in Beijing on Thursday for a new round of trade negotiations with Chinese officials. The negotiations will be followed by another round in Washington next week.
