South Korean President Lee Jae-Myung and Chinese President Xi Jinping maintain active diplomatic channels centered on economic cooperation, supply chain stability, and Korean Peninsula security amid Lee's emphasis on reducing military tensions with North Korea. A telephone conversation on October 2, 2026, addressed elevating their strategic cooperative partnership, with Xi highlighting mutual interests and Lee expressing readiness for deeper engagement. Lee has also sought Chinese mediation on denuclearization and peace initiatives during recent contacts, while balancing these efforts against close U.S. alliance coordination, including multiple summits with President Trump. Bilateral trade remains substantial, supporting incentives for continued high-level dialogue, though North Korean actions and U.S.-China dynamics introduce variables that could influence the timing of additional meetings.
