Vienna - Austria’s chancellor has described parts of U.S. President Donald Trump’s foreign policy as “very successful” as he prepares to visit Washington this week.

Chancellor Sebastian Kurz told Sunday’s edition of Austrian newspaper Die Presse one of the main aims of his visit is to help avert a trade war.

On Saturday, German Chancellor Angela Merkel said U.S. authorities appear to have concluded that European cars were a national security threat.

Kurz is expected at the White House on Wednesday. He pointed to differences with Trump on trade and the Iran nuclear deal, but praised the president’s support for Israel and efforts to secure peace on the Korean Peninsula.

The Austrian leader was quoted as saying “Trump is running, in part, a very active and also very successful foreign policy.”
