WASHINGTON: US Treasury Undersecretary Jay Shambaugh met on Friday with China’s new ambassador to the United States, Xie Feng, holding a discussion aimed at maintaining open communications between the world’s two largest economies, the Treasury said.

“The meeting was candid, constructive, and part of ongoing efforts to maintain open lines of communication and responsibly manage our bilateral relationship,” the Treasury said in a statement.

Shambaugh, who heads international affairs at Treasury, raised US concerns with Xie, but “emphasized the importance of the two largest economies closely communicating on global macroeconomic and financial issues and working together on global challenges.”

Bilateral engagement on economic issues has increased recently, but tensions remain in security-related areas with China’s defense minister declining a meeting with US Defense Secretary Lloyd Austin at a security summit in Singapore.

Last week, US Trade Representative Katherine Tai and Commerce Secretary Gina Raimondo met separately with Chinese Commerce Minister Wang Wentao, with both sides trading objections about each other’s trade, investment and export policies.
