MOSCOW, March 22 - Moscow Mayor Sergei Sobyanin has called for strengthening the social and economic relations between Moscow and Kiev.

"In order to catch up with what has been lost over the previous years due to various political circumstances," Sobyanin said at a meeting with Kiev City State Administration Head Oleksandr Popov in Moscow Mayor's Office on Monday evening.

"The interregional cooperation between our countries will largely depend on how relations between Moscow and Kiev will develop," the mayor said.
