The top diplomats are holding talks on the sidelines of Association of Southeast Asian Nations (ASEAN) events. Lavrov and Rubio last met in the Saudi capital of Riyadh during the February 19 negotiations between Russian and US delegations.
The meeting kicked off at about 1:14 p.m. Moscow time (10:14 a.m GMT).
The US secretary of state was the first to arrive at the venue of the meeting, and Lavrov entered the conference room some five minutes later. After that, journalists were invited into the room.
The top diplomats began talks without making comments to the media even though US correspondents tried to ask Rubio questions.
