South Korea and Japan Agree to Expand Energy Stockpiling and Swap Deals Amid Gulf Supply Strain

ANDONG, South Korea, on Tuesday, May 19: President Lee Jae Myung and Japanese Prime Minister Sanae Takaichi met in Lee's hometown and came away with an agreement to expand cooperation on liquefied natural gas and crude oil supply. The package covers stockpiling and swap arrangements for petroleum products, according to what the two leaders said after their talks.

The reason is plain in how they described it. Both countries depend heavily on imported energy, and supply disruption from the war in the Gulf has strained their economies. They said they would deepen coordination to stabilise their supply lines and would also widen cooperation to include other Asian partners.

Lee put it in a joint press statement. Recent instability in supply chains and energy markets stemming from the situation in the Middle East, he said, had underscored the need for close cooperation between the two countries.

Takaichi added detail on the mechanics. The two governments launched a bilateral initiative aimed at strengthening the resilience of their energy supply, including building up reserves in the Indo-Pacific. Part of that effort, she said, is assessing energy security through measures such as mutual swap transactions for crude oil, petroleum products and LNG. The wording points to swaps being assessed rather than finalised, and the reporting does not set out volumes, prices or timelines.

Energy was not the only subject. The leaders reaffirmed stronger security coordination, including trilateral cooperation with the United States, as they face shared challenges such as North Korea and wider regional tensions. Lee said that recently upgraded vice ministerial-level security talks between Seoul and Tokyo marked meaningful progress in institutionalising defence dialogue.

The Andong meeting was the sixth between Lee and Takaichi since Lee took office, and the second this year under their shuttle diplomacy framework, in which the leaders visit each other's countries in turn. Both said the quick succession of meetings, including visits to each other's hometowns, showed the depth of trust between the two countries and a broadening of cooperation beyond the capitals to regional and economic ties.

That warmth sits alongside longstanding historical disputes between the two nations, which have nonetheless sought closer coordination. Their governments are putting greater emphasis on economic security, advanced technology cooperation including artificial intelligence, and regional stability.

The day was also set to include symbolic touches. The leaders were to attend a banquet featuring Korean and Japanese cuisine, meant to symbolise bilateral friendship, followed by cultural performances: a piano recital and a traditional riverside firework and pansori programme.

What to watch next is whether the swap concepts become concrete arrangements, and whether the security coordination, trilateral work with the US included, moves further along.
