"The EU foreign ministers had a very good meeting with Secretary of State Rex Tillerson today," Mikser said in a brief interview with BNS on the sidelines of a NATO foreign ministers meeting at the alliance's headquarters in Brussels.

Mikser said that this has been the first meeting in this format during the tenure of the new U.S. administration, and that he is glad that it happened during the Estonian presidency of the EU council.

Mikser said that the meeting included the discussion of security issues and areas of tension across the globe, and that it addressed Ukraine, Yemen, Syria, North Korea, and Iran.

In addition the meeting discussed topics unrelated to security but important for transatlantic dialogue. These included trade and climate policy, Mikser said. "It was an extremely candid and mutually constructive discussion," he added.

According to Mikser, it can be said that the new U.S. administration's policy towards the European Union has been more active, more intense, and more constructive than it was generally feared before the Trump administration took office.
