Merkel says US calling European cars a threat is 'frightening'

German Chancellor Angela Merkel on Saturday labelled as "frightening" tough US trade rhetoric planning to declare European car imports a national security threat.

"If these cars... suddenly spell a threat to US national security, than that is frightening to us," she said.

Merkel pointed out that the biggest car plant of German luxury brand BMW was not in Bavaria but in South Carolina, from where it exports vehicles to China.

"All I can say is it would be good if we could resume proper talks with one another," she said at the Munich Security Conference.

"Then we will find a solution."
