China envoy warns of 'destructive forces' trying to undermine US ties

China’s envoy to the United States has said the two countries were trying to resolve their differences over trade, but warned that forces were trying to drive a wedge between the two. Cui Tiankai, speaking at a dinner hosted by the US-China Business Council on Wednesday, said US-China ties were at a critical crossroads due to trade frictions, but it was possible to return to a better path.
