South Korean President Lee Jae-myung and Mongolian President Ukhnaa Khurelsukh issued a joint declaration heralding a “golden age” of bilateral relations this week.

The diplomatic push aims to strengthen economic ties and secure critical resource cooperation through a formal trade framework. This visit marks the first time a Korean head of state has traveled to Mongolia in 15 years [1].

Meeting at Sukhbaatar Square in Ulaanbaatar, the two leaders reached a principle agreement on negotiations for a Comprehensive Economic Partnership Agreement (CEPA) [2]. The agreement focuses on advancing economic partnerships, and pledging to increase the total volume of trade between the two nations [2].

Officials highlighted the significance of the visit with a ceremony that included the launch of 21 fireworks [3]. The event served as a backdrop for the leaders to discuss expanding cooperation across multiple fields, ranging from infrastructure to trade logistics [2].

The CEPA negotiations are intended to lower trade barriers and create a more predictable environment for businesses in both South Korea and Mongolia. By establishing this framework, both governments seek to diversify their economic partners, and stabilize supply chains for raw materials.

“a “golden age” of Korea‑Mongolia relations”

The move toward a Comprehensive Economic Partnership Agreement suggests South Korea is prioritizing the diversification of its mineral and resource supply chains. By strengthening ties with Mongolia, Seoul can reduce reliance on traditional regional powers while providing Ulaanbaatar with the investment and technology needed to modernize its economy.
