China is willing to support normal cooperation with US companies, the country’s Ministry of Commerce said, just days after Chinese airlines rejected taking delivery of any new jets from US planemaker Boeing Co.

BEIJING (Reuters) -Chinese airlines and Boeing have been severely impacted by U.S.-imposed tariffs, disrupting regular trade and investment activities of many businesses, the Chinese commerce ministry said in a statement on Tuesday.

China has sent back planes it ordered from the US in its latest retaliation over Trump tariffs, the boss of aircraft maker Boeing has said. Kelly Ortberg said two planes had already been returned and another would follow after trade tensions between the two countries escalated.
