Xi Reasserts Regional Dominance in High-Stakes Seoul Summit

BEIJING — Chinese President Xi Jinping effectively dismantled a key pillar of U.S. containment strategy on Monday, hosting South Korean President Lee Jae-myung for a summit that underscored Beijing’s enduring gravitational pull. For investors gauging the stability of the Chinese Communist Party leadership through 2026, the meeting offers a stark demonstration of Xi’s executive control and strategic agility.

Capitalizing on the political shift following the impeachment of pro-U.S. President Yoon Suk Yeol, Xi has secured a critical diplomatic opening. The embrace of President Lee—who termed Xi a "truly reliable neighbor" in a sharp reversal of the previous administration's "values-based diplomacy"—marks a significant geopolitical coup. By deftly peeling Seoul away from the nascent U.S.-Japan-ROK trilateral bloc, Xi is securing China’s periphery, a move that signals a consolidated foreign policy apparatus rather than one distracted by internal dissent.

The sequencing of the summit reveals a calculated assertiveness. By hosting Lee prior to his upcoming Tokyo visit, Beijing has effectively wedged the Japan-South Korea leg of the regional security triangle. This maneuver, coming amidst friction over Japanese PM Sanae Takaichi’s hawkish Taiwan rhetoric, demonstrates a sophisticated command structure in Beijing—further evidenced by the disciplined progression of talks despite a concurrent North Korean hypersonic missile test.

Beyond optics, the signing of over 10 agreements on supply chains and critical minerals bolsters Xi’s economic resilience against Western sanctions. The summit presents a clear counter-narrative to speculation regarding leadership turmoil: Xi appears not as a leader facing an imminent exit, but as one actively and successfully reshaping the regional order to insulate his regime.
