SOCHI, May 14. /TASS/. Russia believes it will be able to reach an agreement with the US on extending the New Strategic Arms Reduction Treaty (New START), Russian Foreign Minister Sergey Lavrov told reporters on Tuesday at a joint news conference with US Secretary of State Michael Pompeo.

"We proceed from the assumption that we will be able to reach an agreement [on extending the accord] within the framework of the bilateral joint advisory commission," he noted.

Lavrov added that Moscow was concerned about the re-equipment of US submarines and bombers capable of carrying nuclear weapons.

"The treaty envisages specific procedures, which should make it possible for the other party to ensure that this re-equipment is done in such a way as to make a return to the nuclear capabilities of respective launchers and bombers impossible," he stressed. "These issues are discussed by the joint advisory commission overseeing the implementation of the treaty, and we hope that this discussion will yield positive results.".
