The Kremlin said on Wednesday it was premature to talk in tangible terms about a possible meeting between Russian President Vladimir Putin and his U.S. counterpart Joe Biden, who has proposed the two leaders meet, but adding it would study the proposal.

"It is early to talk about this meeting in terms of specifics. This is a new proposal and it will be studied," Putin's spokesman Dmitry Peskov told reporters.

In a phone call on Tuesday, Biden proposed a summit of the estranged leaders to tackle a raft of disputes.
