President Lee Jae-myung departed Ulaanbaatar for Seoul on the 11th (local time) after wrapping up a state visit to Mongolia. This concluded a five-day, three-night trip that included attending the North Atlantic Treaty Organization (NATO) summit in Türkiye.
On the 9th, the first day of the Mongolia visit, Lee held a summit with President Ukhnaagiin Khurelsukh of Mongolia and adopted a joint declaration on strengthening the Korea–Mongolia strategic partnership. The declaration included the statement, "The two countries will further develop bilateral relations and open a 'golden era' in Korea–Mongolia ties."
The declaration also stated, "As parties to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the two countries express support for the three pillars of nonproliferation, disarmament, and peaceful use." It also included the phrase, "Korea explained its policy of peaceful coexistence and shared growth on the Korean Peninsula, including exchanges, normalization of relations, and a phased approach to denuclearization."
On the second day of the visit, Lee met in succession with Parliament Speaker Sandag Byambatsogt (No. 2 in protocol) and Prime Minister Luvsannamsrain Oyun-Erdene (No. 3 in protocol). That evening, he attended a state banquet hosted by President Khurelsukh. On the final day, as the guest of honor at Naadam, Mongolia's largest festival, he personally tried archery, one of its three main events. This is the first time a Korean head of state has been invited as the guest of honor at Naadam.
