Russian President Vladimir Putin extended congratulations to U.S. President-elect Donald Trump on his inauguration day, expressing optimism for renewed dialogue between Moscow and Washington.

Speaking during a rare Monday meeting of Russia’s Security Council—televised across state media—Putin underscored his openness to discussions on critical global issues, including the war in Ukraine and nuclear arms control, reports Reuters.

“We see the statements by the newly elected president of the United States and members of his team about the desire to restore direct contacts with Russia,” Putin remarked.

He also welcomed Trump’s commitment to averting global conflict.

“We also hear his statement about the need to do everything possible to prevent World War Three. We, of course, welcome this attitude and congratulate the elected president of the United States of America on taking office.”

This statement, Reuters says highlights cautious optimism within the Kremlin that Trump could pave the way for a thaw in U.S.-Russia relations, which have been strained to their lowest point since the Cuban Missile Crisis in 1962.

However, Russian officials privately acknowledge that these hopes could be dashed by Washington’s policy complexities.
