South Korea's Strategic Crossroads: Lee Jae-myung's Visit to India

As South Korea grapples with the implications of changing global dynamics, President Lee Jae-myung's impending three-day visit to India marks a strategic inflection point for both nations and the wider Indo-Pacific region. With the regional order that once underpinned stability fragmenting, economic interdependence increasingly viewed as a liability, and long-standing security guarantees under strain, this visit is anything but routine.

When Washington began pulling missile defense assets from South Korea for the Iran war in March 2026, President Lee could only voice his objections. Days later, he called for a faster transfer of wartime operational control to South Korea. These developments have underscored a pressing reality: Seoul must establish clear strategic priorities to manage its dependence on an unpredictable ally.

The geopolitical environment is shifting, and South Korea finds itself at a decisive crossroads. Internal divisions concerning foreign policy orientation—particularly between those advocating for closer ties with the United States and Japan, and those favoring expanded engagement with China and Russia—are increasingly shaping tangible policy outcomes. Approximately 28,500 US troops remain stationed on the Korean peninsula, and the US-South Korea alliance has endured for over seven decades. Yet, perceptions of a less-than-decisive US military performance in crises linked to Iran are bolstering calls in Seoul for a more autonomous foreign, security, and defense posture.

China, accounting for approximately 20–25 percent of South Korea’s total trade, has become Seoul’s largest trading partner. This economic interdependence complicates South Korea's strategic calculations. As the frameworks that once supported growth and security erode, the need for a recalibrated approach to international relations is becoming increasingly urgent.

Lee’s visit to India is not just about enhancing bilateral trade, which has surpassed $27 billion in recent years with ambitions to reach $50 billion. It is about aligning strategic priorities and reshaping perceptions within both countries’ policy communities. Incremental, transactional engagement is no longer sufficient; the stakes are too high.

For South Korea, the US–Japan–South Korea deterrence partnership, the China–Japan–South Korea functional cooperation, and the emergent China–Russia–North Korea counter-alignment increasingly define the security environment in Northeast Asia. The US–Japan–South Korea framework received a renewed institutional boost at the 2023 Trilateral Leaders’ Summit, yet it remains politically sensitive in South Korea and vulnerable to friction with Japan.

Meanwhile, the China–Japan–South Korea arrangement has a permanent secretariat and a record of practical cooperation, but it remains fragile, disrupted by nationalism and maritime disputes. The China–Russia–North Korea triangle, though not formalized, is becoming increasingly consequential for security on the Korean Peninsula.

Seoul's strategy must evolve beyond slogans about ‘strategic autonomy’ or ‘middle-power agency.’ It should focus on strengthening trilateral consultation, intelligence sharing, and contingency planning, insisting on the institutionalization of cooperation. The goal should be to create a reliable alliance rather than an automatic one, particularly in the face of potential crises in Taiwan or heightened US-China tensions.

As South Korea seeks to navigate these complex dynamics, it must also recognize the importance of its relationship with India. The two nations share converging concerns about supply-chain vulnerabilities, maritime security, and technological resilience. For India, South Korea is not merely a bilateral partner; it is a key player within the broader Indo-Pacific strategic architecture.

India's approach to South Korea has often been framed in transactional terms, encompassing trade agreements and investment facilitation, rather than being situated within a comprehensive strategic vision. This limited engagement has resulted in three principal shortcomings: underutilization of strategic convergence across key sectors, limited influence within South Korean strategic discourse, and a lack of clarity in addressing South Korea's core concerns.

Lee's visit should be seen as a strategic reset. It provides an opportunity to signal long-term commitment and align strategic priorities. Both countries exhibit strong complementarities in technology and supply chain resilience, particularly in semiconductors and electronics manufacturing. Enhanced defense cooperation, which remains underdeveloped, could significantly strengthen both nations' industrial capacities.

Maritime cooperation, especially in the Indian Ocean region, should also be elevated, as it is central to global energy trade and regional stability. Sustained institutional engagement is necessary for both countries to build long-term influence and counter the perception that alignment with China is economically inevitable.

India is well-positioned to offer an alternative framework for cooperation, emphasizing flexibility, resilience, and mutual respect. This aligns closely with South Korea’s imperative to avoid excessive dependence on any single power. Strengthening the India-South Korea partnership enhances strategic autonomy for both countries, reinforcing South Korea’s presence in East Asia and contributing to a more balanced Indo-Pacific order.

As the geopolitical environment continues to evolve, the costs of inaction are considerable. A failure to act decisively could lead to a gradual realignment of South Korea toward China’s orbit, marginalizing India in the region. Such inertia could also weaken the Indo-Pacific architecture, as strategic vacuums are filled by actors willing to act with greater urgency.

In this moment of strategic recalibration, clarity of purpose and ambition are imperative. The upcoming visit must deliver more than symbolic outcomes; it must generate tangible commitments and results that meaningfully redefine the partnership between India and South Korea. The Indo-Pacific order will not be shaped by passive actors but by those who recognize inflection points and act decisively. As President Lee prepares for his visit to New Delhi, the time for strategic engagement is now.
