The trip is thought to be Ratcliffe’s first trip to Russia as CIA director, although he has maintained contact with his intelligence counterparts in Moscow.
He played a role in negotiations for the release of Russian-American citizen Ksenia Karelina’s, who was jailed in Russia for over a year after being accused of providing support to Ukraine.
The CIA was also involved in a 2024 prisoner swap deal with Russia that saw the release of Wall Street Journal reporter Evan Gershkovich, as well as former US marine Paul Whelan and Russian-American journalist Alsu Kurmasheva.
The US has had strained relations with Russia since it launched a full-scale invasion of Ukraine in 2022. Since then, Russia has been isolated on the world stage and faced international economic sanctions.
Ratcliffe appears to be one of the highest-ranking US officials to visit the country during President Donald Trump’s second term.
Trump met Russian President Vladimir Putin at a summit in Alaska last year but the meeting did not lead to a breakthrough. Subsequent US-led peace talks between Russia and Ukraine appear to have stalled.
