Russia’s foreign minister says U.S. President Donald Trump indicated he could make a reciprocal trip to Russia if President Vladimir Putin were able to accept his invitation to the White House.

Sergey Lavrov told Russian state television Friday that Trump mentioned the possibility of traveling to Russia when he called Putin on March 20 to congratulate him on his re-election.

Both the White House and the Kremlin previously revealed that Trump had invited Putin to the White House during the same call, when the two leaders discussed wanting to meet soon.

Lavrov says the Trump administration hasn’t followed up on Trump’s offer.

Lavrov said Russia has urged the U.S. to discuss specifics about such a meeting. He says Russian officials “don’t want to be too obtrusive, but don’t want to be impolite.”
