South Korean President Lee Jae-myung and Mongolian President Ukhnaa Khurelsukh issued a joint declaration to establish a “golden era” of bilateral relations.

This diplomatic shift aims to expand trade and investment between the two nations through a strategic partnership. The agreement focuses on the Comprehensive Economic Partnership Agreement (CEPA), which is intended to reduce trade barriers and facilitate smoother economic exchanges.

During the visit to Ulaanbaatar, the two leaders announced a principled conclusion to the CEPA negotiations [1]. The discussions took place at the presidential residence and Sukhbaatar Square, marking a significant step in formalizing economic ties. The CEPA is expected to serve as the primary framework for increasing the scale of mutual trade and investment [2].

This visit represents the first state visit by a South Korean leader to Mongolia in 15 years [3]. The rarity of such a high-level visit underscores the renewed priority South Korea is placing on its relationship with the landlocked nation.

President Lee and President Khurelsukh said there is a need for a strategic partnership to navigate regional economic challenges. By securing a principled agreement on the CEPA, both governments have set a trajectory for deeper integration in sectors such as mining, infrastructure, and technology. The joint declaration serves as a political commitment to maintain this momentum and elevate the diplomatic status of their interactions [1].

The ceremony in Ulaanbaatar highlighted the symbolic nature of the visit, with both leaders saying historical and cultural ties bind the two peoples. The move to formalize a trade agreement is seen as a practical application of these ties to achieve modern economic growth [2].

“‘golden era’ of bilateral relations”

The principled agreement on the CEPA signals South Korea's intent to diversify its economic partnerships and secure critical mineral supply chains, as Mongolia possesses vast untapped natural resources. By elevating the relationship to a 'golden era,' both nations are attempting to transition from sporadic cooperation to a structured, long-term strategic alliance that reduces reliance on traditional regional powers.
