Bolton hails 'very comprehensive and productive' talks in Russia

US National Security Advisor John Bolton on Tuesday praised "productive" talks with President Vladimir Putin and other Russian officials during a two-day trip to Moscow.

"I had a series of very comprehensive and productive discussions," he told a press conference after the visit in the wake of US President Donald Trump's announcement he would pull out of a nuclear arms treaty with Russia.

A 90-minute meeting with Putin touched on the conflict in Syria and election meddling as well as Trump's decision on the arms treaty, Bolton said. "We discussed our continuing concern with Russian meddling in elections and why it was particularly harmful for Russian-American relations without producing anything in return," he said.

"We had lengthy conversations about arms control issues, the new strategic landscape and the INF (Intermediate-Range Nuclear Forces) treaty." Bolton earlier said Trump wished to meet Putin when the two visit Paris on November 11 for World War I commemorations.

During the press conference he said arrangements were being made for that meeting.
