Two Russian billionaires who have managed to dodge US sanctions over Moscow’s year-old invasion of Ukraine went property shopping with Hunter Biden, dined with then-Vice President Joe Biden, and discussed “favors” they might swap, sources tell The Post.

New details of Joe and Hunter Biden’s association with Yelena Baturina and Vladimir Yevtushenkov flesh out tantalizing clues from the first son’s abandoned laptop. The sources spoke with The Post this week after the duo was yet again spared a fresh batch of sanctions announced by the Treasury Department Friday.

“I think it’s very fishy,” said one source who had firsthand knowledge of the business relationship between Hunter Biden and Yevtushenkov — who is sanctioned by the UK and Australia but not by the US.
