Russia started preparing the ground for last week’s breakthrough on Syria’s chemical weapons problem more than a year ago and helped arrange direct contacts on the issue between Washington and Damascus.

“It all started, not a week ago, but in Los Cabos [in June 2012] where the Russian and U.S. Presidents met on the sidelines of a G20 summit,” Russian Foreign Minister Sergei Lavrov revealed.

At that meeting Mr. Putin and Mr. Obama, according to Mr. Lavrov, both “voiced grave concern” that Syria’s chemical weapons could “fall into the wrong hands”.
