South Korean President Lee Jae Myung concluded a landmark six-day state visit to India and Vietnam on Friday, April 25, signing a combined 27 memorandums of understanding aimed at fortifying Seoul's energy security and diversifying critical mineral supply chains — moves driven by escalating disruption from the US-Iran war now entering its eighth week. The trip signals a strategic pivot by South Korea to deepen ties with the Global South as traditional supply routes face unprecedented pressure.

India Summit: Critical Minerals, Shipbuilding and a $50 Billion Trade Target

In New Delhi, President Lee held a bilateral summit with Indian Prime Minister Narendra Modi, agreeing to accelerate cooperation across critical minerals, energy, artificial intelligence, finance and shipbuilding. The two leaders also pledged to fast-track upgrades to their Comprehensive Economic Partnership Agreement (CEPA), with an ambitious target of doubling bilateral trade from the current $25 billion to $50 billion by 2030.

Fifteen MOUs were signed on the sidelines of the Lee-Modi summit, covering a broad spectrum of sectors. Among the most strategically significant was an agreement laying the groundwork for the joint construction of a shipyard in India — a move that could reshape South Asia's maritime manufacturing landscape.

President Lee stated following the summit: In light of recent developments in the Middle East, we will continue to strengthen bilateral cooperation to ensure a stable supply of energy resources and key raw materials. This carries significant weight as South Korea imports nearly 70% of its crude oil through the Strait of Hormuz, a chokepoint now under severe stress due to the ongoing conflict.

Notably, India — now the world's fourth-largest economy with a population of approximately 1.5 billion — has emerged as a preferred partner for nations seeking supply chain alternatives outside China and the volatile Middle East corridor. This aligns with New Delhi's own push to attract advanced manufacturing investment.

Vietnam Visit: Nuclear Energy Revival and $150 Billion Trade Goal

In Hanoi, President Lee became the first foreign leader to visit Vietnam since To Lam was elected state president earlier in April 2025, consolidating power by simultaneously holding the country's two most powerful positions. The symbolic timing of Lee's visit underscores Seoul's intent to build early-mover advantage with Hanoi's new leadership.

The two sides agreed to deepen cooperation across energy, infrastructure, technology and supply chain coordination, reaffirming a bilateral trade target of $150 billion by 2030 — up significantly from $94.6 billion in 2024. Twelve MOUs were signed covering energy, infrastructure, artificial intelligence and transportation.

Perhaps the most consequential development from the Hanoi leg was the emergence of nuclear energy as a new pillar of cooperation. Vietnam is seeking a credible partner to revive a nuclear power program shelved in 2016 due to financing constraints. In response, Korea Electric Power Corporation (KEPCO) and Vietnam National Industry-Energy Group signed two MOUs covering joint feasibility studies and financing for potential nuclear power development projects.

On Thursday, President Lee also held separate meetings with Vietnamese Prime Minister Le Minh Hung and National Assembly Chairman Tran Thanh Man to further advance bilateral ties at multiple levels of government.

The Bigger Picture: Middle East Conflict Reshaping Asia's Energy Architecture

The urgency behind Lee's tour cannot be overstated. The US-Iran conflict, now in its eighth week, has disrupted energy flows through the Strait of Hormuz — a critical chokepoint for South Korea's imports of crude oil and industrial feedstocks like naphtha, essential for petrochemicals and semiconductor manufacturing. Any prolonged blockade or escalation could trigger severe supply shocks for Seoul's export-driven economy.

Vietnam has already emerged as a key manufacturing base for major South Korean conglomerates including Samsung and LG, with the country accounting for a substantial share of their global electronics output. Deepening ties now positions Seoul to further reduce dependence on China-based production amid ongoing US-China trade tensions.

India offers access to critical minerals — including rare earths, lithium and cobalt — vital for South Korea's battery and semiconductor industries. As China tightens export controls on rare earth processing, Seoul's pivot to New Delhi is a direct hedge against Beijing's growing leverage over global tech supply chains.

Strategic Significance: South Korea's Global South Engagement

National Security Adviser Wi Sung-lac stated that President Lee's trip laid the groundwork for deeper economic cooperation with key partners, explicitly referencing Seoul's expanding engagement with the Global South. As the G7-led economic order fragments, middle powers like South Korea are recalibrating their foreign economic policy to build redundancy and resilience.

Critics and analysts will note that MOUs must be converted into binding agreements and actual capital flows to deliver strategic value. South Korea's track record on CEPA implementation with India has historically been slow, with the original agreement signed in 2009 yet to be substantially upgraded despite years of negotiation.

Looking ahead, follow-up working-level talks on CEPA upgrades and nuclear feasibility studies are anticipated in the coming months. Whether these high-level commitments translate into durable partnerships will determine Seoul's resilience in an increasingly fragmented global order.
