Russian Foreign Minister Sergei Lavrov praised US President Donald Trump for being blunt in discussing international issues, RIA Novosti reported.

"He avoids any ambiguity and tries to say directly what he thinks," he said. "This is not always found among politicians of the highest category, but this, in my opinion, is a very, very productive approach."

Lavrov paid a visit to the US on December 10, during which he held talks with Secretary of State Mike Pompeo and met with President Donald Trump.

The parties discussed Syria, Ukraine, Libya, Afghanistan and Venezuela and touched upon the issues of strategic stability, the fate of START-III and the situation around the North Korea.
