China's Xi to visit Russia from March 20-22: Kremlin

The visit comes as China offers to broker peace in Ukraine.

"During the talks, they will discuss topical issues of further development of comprehensive partnership relations and strategic cooperation between Russia and China," the Kremlin said.

"A number of important bilateral documents will be signed," it added.

China and Russia struck a "no limits" partnership in February 2022, when Putin was visiting Beijing for the opening of the Winter Olympics, weeks before Russia attacked Ukraine.

The two sides have since continued to reaffirm the strength of their ties. Trade between the two countries has soared since the war, and China is Russia's biggest buyer of oil, a key source of revenue for Moscow.
