US officials will be in Beijing February 14-15 for the third round of talks aimed at heading off an escalation of the ongoing trade war with China, the White House announced Friday.

Negotiators are working towards an agreement before the 90-day tariff truce expires March 1, after which the US is set to more than double punitive duties on $200 billion in Chinese goods.

US Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin will lead the delegation, which also includes David Malpass, who President Donald Trump has nominated to be president of the World Bank, according to the statement.

However, strident White House China critic Peter Navarro was not listed as part of the US team.

While officials seemed optimistic after talks last week in Washington, more recent comments have jarred financial markets, amplifying concerns about how the dispute will impact global growth.
