United States President Joe Biden was due to meet eastern European leaders today, a day after vowing Russia would never see victory in Ukraine.
Russia president Vladimir Putin has said the country will press on with its nearly year-long war.
On Tuesday, he accused the West of escalating the conflict and announced that Moscow would suspend participation in the New nuclear arms treaty with Washington.
The Russian president said increasingly stringent sanctions on the country “will not succeed” and vowed his country would keep fighting to “systematically” achieve its aims.
The 2010 deal is the last remaining arms control treaty between the world’s two main nuclear powers.
Speaking hours later in the capital of NATO ally Poland, Biden pledged that “Ukraine will never be a victory for Russia.”.
The US president had a day earlier made a surprise visit to Kyiv, his first since the invasion began and just days before the war’s one-year anniversary.
