President Lee Jae-myung visited the United States and Mexico to promote South Korea's peace policy on the Korean Peninsula to the international community, worked hard to create a breakthrough in security negotiations and strengthen economic cooperation. In the United States, he discussed security issues such as cooperation in building nuclear-powered submarines through a 'surprise meeting' with former President Trump, and promised efforts to transfer wartime operational control. In Mexico, he concluded negotiations on revising the investment guarantee agreement, supporting the advancement of Korean companies into Central and South America. He also publicly criticized the controversy over the repatriation of Ukrainian prisoners of war, and at a gathering of Koreans in Mexico, he clearly stated the end of his term and expressed his opposition to the constitutional amendment for re-election.
