South Korea appears to be undergoing a subtle yet potentially profound recalibration of its foreign policy. Under President Lee Jae-myung, who assumed office in June 2025, Seoul is signalling an intent to navigate more flexibly between superpowers rather than maintaining a rigid alliance structure. The change reflects both shifting global dynamics and domestic considerations: an increasingly fraught relationship between Washington and Beijing, rising economic interdependence with China, ongoing security threats from the North, and internal pressure for more balanced and pragmatic diplomacy. The question on many minds now is: is South Korea quietly moving away from the United States and inching toward China — or simply adjusting its alignment in a volatile world?
Lee’s new administration describes its approach as “pragmatic foreign policy,” aiming to strike a balance among major powers, including China and Russia, while still preserving the essential alliance with the United States. “We believe that we must not antagonize China, but equally cannot abandon the alliance with the U.S.,” senior officials have expressed. This nuance captures the delicate position Seoul finds itself in: tasked with preserving national security under the U.S.-backed defense umbrella, while protecting and advancing its economic interests, many of which remain deeply tied to China.

Economically, the ties with China remain hard to ignore. For decades, Beijing has been South Korea’s top trading partner. Despite a recent decline in some sectors, China continues to absorb a large share of South Korean exports — especially in semiconductors, electronics, manufacturing inputs, and consumer goods. For many South Korean businesses, China is not simply another large market, but an integrated supply-chain partner. The reliance is mutual: South Korean companies depend on China’s manufacturing ecosystem, while China still needs advanced Korean exports for its own tech and consumer markets.

At the same time, Seoul is carefully managing its relationship with Washington. The U.S.–South Korea security alliance remains foundational, especially in light of persistent threats from the North and regional instability. But pressures from the U.S. — including demands for greater defense spending, shifting strategic priorities, and trade tensions — have stirred discomfort in Seoul. Many in the Lee government perceive the demands as burdensome or misaligned with South Korea’s broader national interests. A key concern: participating too fully in U.S.-led initiatives against China could expose South Korea to economic retaliation and supply-chain disruption. Korea Joongang Daily+2Asia Times+2
Against this backdrop, many in Seoul view a recalibrated partnership with China as both pragmatic and necessary. China’s economic importance, paired with the desire to avoid antagonizing Beijing on issues like Taiwan or South China Sea tensions, has reinforced the case for diplomatic flexibility. Indeed, the new South Korean foreign policy appears designed less to choose a side, and more to navigate between them — maximizing benefit while minimizing exposure.

Some of the most visible signals of this recalibration came in the weeks following Lee’s election. While his administration has not abandoned U.S. partnerships — Seoul engaged in negotiations with Washington on trade and security issues — it also showed willingness to repair and deepen relations with Beijing. Officials emphasized that China remains a “key partner,” even as they expressed reservations about some Chinese policies. In public statements, Seoul stressed that improving ties with China did not necessarily mean undermining its commitments to the U.S. and regional security frameworks.

That said, the shift is not so dramatic that it upends the alliance overnight. The Lee government has so far avoided sharp breaks with Washington. It continues to rely on U.S. security guarantees, especially given the volatile situation with the North. Military cooperation remains on the table, and there is still recognition in Seoul that U.S. backing provides insurance against regional threats that China cannot formally offer. In that sense, the policy evolution reflects hedging rather than departure. Asia Times+2Chatham House+2
Still, the recalibration carries risks. Many in South Korea worry that deeper engagement with China may come at the expense of strategic clarity and long-term deterrence. China’s assertive regional behavior — in maritime disputes and toward Taiwan — remains an unresolved background. By avoiding criticism or confrontation, Seoul may lose influence or credibility among U.S. allies who see China as a strategic competitor. There is also concern that in pursuing balance, South Korea could end up with neither strong security guarantees nor robust economic stability — a worst-case outcome some analysts refer to as “caught between giants.”
Additionally, Beijing is not a monolithic partner. Economic ties with China come with strings: pressure to conform politically, possible coercion in sensitive sectors, and risks associated with overdependence. Some sectors of the South Korean economy, especially advanced technology, are vulnerable to shifting Chinese priorities or supply-chain disruptions. Recognizing this, Seoul seems to be preparing measures to “de-risk” certain engagements: for example, limiting sensitive technology exports, diversifying supply chains, and maintaining alternative partnerships beyond China.

In many ways, what we are seeing is less a pivot and more a recalibration — an attempt by Seoul to redefine what being a middle power means today. Rather than siding decisively with either Washington or Beijing, South Korea seems to be staking out a more autonomous space: partnering with the U.S. for security, engaging China for economic opportunity, and preserving flexibility to respond to unpredictable global shifts.
How this will play out remains uncertain. Much depends on developments in Northeast Asia — especially the actions of the North, China’s regional ambitions, U.S. strategic decisions, and how well Seoul can manage domestic expectations and external pressures. If tensions between the U.S. and China intensify further, or if Beijing becomes more coercive, Seoul may be forced to choose. Alternatively, if China continues to offer substantial economic incentives while the U.S. alliance shows signs of strain, South Korea could gradually tilt more toward Beijing.
For now, though, the Lee administration appears to prefer ambiguity over alignment. Its foreign-policy path represents a reimagined form of statecraft — one grounded in cost-benefit calculations, hedging, and flexibility. Whether this proves to be tactical caution or long-term realignment will shape the future security and economic contours of Northeast Asia.
