Russian President Vladimir Putin says there is no need for a Russia-China military alliance now but the idea of a future one can't be ruled out.

Putin was asked during a video conference with international foreign policy experts Thursday if a military union between Moscow and Beijing was possible. He replied that “theoretically, it’s quite possible to imagine it.”

Russia and China have hailed their “strategic partnership,” but so far rejected any talk about the possibility of their forming a military alliance.
