Japan and Vietnam signed a 10 billion dollar energy deal in 2026, and the real critical minerals commitment sits inside it

The Japan Vietnam energy deal for 2026

The Japan Vietnam energy deal signed in Hanoi on 2 May 2026 is not, by itself, a clean energy deal. Prime Minister Sanae Takaichi of Japan and Prime Minister Le Minh Hung of Vietnam signed 6 agreements that day, backed by POWERR Asia, a Japanese government fund of about 1.5 trillion yen, 10 billion dollars, that Takaichi announced the month before. Its purpose is to help Asian countries keep buying crude oil, petroleum products and liquefied natural gas after a Middle East conflict disrupted supply through the Strait of Hormuz.

The two sides identified economic security as a new priority area for bilateral cooperation.

An overview of POWERR Asia published directly by the Japanese government splits the fund into emergency loans and insurance for alternative crude oil, including crude from the United States, and a longer plan that stockpiles oil and spreads energy sources across liquefied natural gas, solar power, small modular nuclear reactors and critical minerals. That document states the fund could enable imports of up to 1.2 billion barrels of crude oil a year, an amount it calls equal to about 1 year of crude oil imports for the entire Association of Southeast Asian Nations region, known as ASEAN.

The Japan Vietnam critical minerals commitment

The part of this visit that matters most for clean energy is narrower than the fund that brought the 2 leaders together. The joint statement named critical minerals, alongside semiconductors, artificial intelligence and space, as a new priority area, with a specific commitment to strengthen rare earth supply chains in Vietnam. Rare earth elements are minerals that wind turbine magnets, electric motors and batteries depend on. China refines between 85% and 100% of the world rare earth supply.

Vietnam ranks 6th in the world for rare earth reserves, but its biggest known deposit, Dong Pao, remains undeveloped. Vietnam amended the Law on Geology and Minerals, effective 1 January 2026, reclassifying rare earths as strategic minerals, banning exports of unprocessed rare earth ore, and restricting exploration and processing rights to state designated companies. Vietnamese authorities have already arrested 14 people over illegal rare earth extraction at the Yen Phu mine since October 2023.

Money moving alongside the Japan Vietnam energy deal

Two way trade between Japan and Vietnam reached 38.6 billion dollars in the first 8 months of 2026, up 15% from a year earlier, and Japanese investment into Vietnam over that window came to 2.3 billion dollars, up 14.3%, the Japanese ambassador to Vietnam states. That followed a weaker start to the year, Japanese investment into Vietnam fell about 75% to 233 million dollars in the first 3 months of 2026, even as trade kept climbing. A separate, older framework, Asia Zero Emission Community, funds 15 pilot projects worth about 20 billion dollars for the Vietnamese power plan, leaning toward natural gas rather than wind or solar.

reaffirmed the importance of resolving disputes in the South China Sea through peaceful means based on international law.

The 10 billion dollars Japan pledged through POWERR Asia is a fraction of what the Asian Development Bank has committed across the region, 70 billion dollars for digital and energy infrastructure. The honest reading is not that Japan and Vietnam signed a green energy pact. It is that a mostly fossil fuel focused security pact carries a real commitment on the mineral supply chains clean energy manufacturing depends on.
