China is sending an envoy to the United States for talks aimed at cooling a trade dispute that threatens to upend markets from soy beans to steel.

The Foreign Ministry said Vice Premier Liu He will visit the U.S. from Tuesday to Saturday for consultations with U.S. Treasury Secretary Steve Mnuchin and his team.

That follows a visit by the U.S. officials to Beijing earlier this month, where they conveyed a demand that China slash its trade surplus with the U.S. by $200 billion by the end of 2020.

A rivalry over advanced technology has fueled demands by Washington that China give up policies that favor domestic companies. Beijing considers such policies fundamental to its state-driven economic model and vital for its future growth.
