Mr Putin, speaking at the annual meeting of the Valdai Discussion Club via video conference on Thursday, signalled deepening ties between Moscow and Beijing amid growing tensions in their relations with the United States.
When asked during the conference if a military union between Moscow and Beijing was possible, Mr Putin replied that "we don't need it, but, 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 a military alliance.
