U.S. President Joe Biden left North Korea out of his first State of the Union address Tuesday that laid out various challenges facing his country, including the ongoing Russian invasion of Ukraine.

The U.S. leader, however, thanked South Korea, along with dozens of other countries, for condemning what he called Russia's "unjustified" and "totally unprovoked" aggression on Ukraine.

"Along with twenty-seven members of the European Union including France, Germany, Italy, as well as countries like the United Kingdom, Canada, Japan, Korea, Australia, New Zealand and many others, even Switzerland, are inflicting pain on Russia and supporting the people of Ukraine," Biden said in his address, delivered in a joint session of U.S. Congress.

South Korea has agreed to suspend financial transactions with seven major Russian banks as part of the international efforts to hold Russia accountable for its invasion of Ukraine.

The chief of its U.N. mission, Ambassador Cho Hyun, also urged Russia to immediately withdraw its troops from Ukraine while addressing an emergency meeting of the U.N. General Assembly, held earlier Tuesday in New York.
