Russian President Vladimir Putin has reassured his USA counterpart Donald Trump that Moscow remains "open to dialogue" despite the year ending without the hoped-for warming of relations, the Kremlin said on Sunday.
The tension between the two countries was reflected when Trump cancelled his meeting with Putin which was scheduled to take place on the sidelines of the G20 summit in Argentina.

Meanwhile, Putin expressed confidence in his address to South Korean President Moon Jae-in that the two countries will have closer interaction to help consolidate peace and stability on the Korean Peninsula and Northeast Asia in general.

Mr Putin's message to Mr Assad "stressed that Russian Federation will continue to provide all-around assistance to the government and people of Syria in their fight against terrorism and efforts to protect state sovereignty and territorial integrity", according to the Kremlin summary.
