Constant contacts between Russia and the United States on Syria are the only positive example of their bilateral cooperation, Russian Defense Minister Sergei Shoigu said on Tuesday.

"We maintain contacts [with the US] on the hotbeds of tension," Shoigu said.

"This certainly refers to Syria, where we actually work constantly and keep our relations with US colleagues on track."

The minister stressed that so far this has been the only example of efficient cooperation between the US and Russia "which allows to prevent serious incidents in the air on Syria’s territory." "As for the rest, we need a more active dialogue," Shoigu noted.
