French President Emmanuel Macron and South Korean President Lee Jae Myung have agreed to deepen defence and energy cooperation amid rising global instability caused by the Middle East conflict. During a joint summit in Seoul on April 3, 2026, the two leaders pledged to strengthen military ties, enhance joint production of critical defence technologies, and secure energy supply routes disrupted by the war in Iran. Macron arrived in South Korea on April 2 after concluding a visit to Japan, marking the first state visit by a French president since 2015. The trip is part of France's broader effort to expand its strategic footprint in Asia amid escalating regional and international tensions.
Lee stated that both nations agreed to "share policy-related experiences and strategies in order to jointly address the economic and energy crises triggered by the Middle East war." The Strait of Hormuz, a crucial maritime passage for global oil shipments, has been effectively closed by Iran since late February in response to US-Israeli military actions. This closure has severely impacted energy-dependent economies like South Korea. Macron dismissed the idea of a military operation to reopen the strait, calling it "unrealistic," diverging from US President Donald Trump's call for allies to take action. Instead, the two leaders emphasized collaboration on energy security, including joint efforts to protect shipping lanes.
Both countries, major arms producers, agreed to expand cooperation in aerospace, defence manufacturing, and joint military exercises. They also plan to sign preliminary agreements in critical minerals, semiconductors, quantum technologies, nuclear energy, and wind power. South Korea's Korea Hydro & Nuclear Power will sign memoranda of understanding with French firms Orano and Framatome to secure nuclear fuel supplies and pursue joint ventures in the global nuclear market. Bilateral trade is targeted to rise from $15 billion in 2025 to $20 billion by 2030. Macron is scheduled to meet executives from Samsung, Naver, and Hyundai Motor to promote French exports and attract Korean investment into France's technology and industrial sectors.
When Macron calls a military push through the Strait of Hormuz "unrealistic," he is not just rejecting Trump's stance—he is redefining European strategic autonomy in volatile regions. This shift enables countries like South Korea to deepen defence partnerships with EU powers without being drawn into US-led military frameworks. The focus on joint nuclear and critical technology ventures signals a long-term pivot toward self-sufficient supply chains, not just energy security. In a world where chokepoints can be shut overnight, industrial and technological co-production is the new frontline.
