The U.S.has identified cooperation on small modular nuclear reactors (SMRs) as a key priority in its engagement with Southeast Asia amid rising regional electricity demand.

Secretary of State Marco Rubio's attendance at the ASEAN Foreign Ministers’ Meeting in Manila highlighted the administration's emphasis on SMRs, with U.S.Ambassador Kevin Kim stating that 'deep discussions' are underway with multiple Southeast Asian governments.This initiative follows a memorandum of understanding signed by the U.S., Japan, and South Korea at the NATO summit, aiming to accelerate SMR deployment in the Indo-Pacific.The U.S.has also unveiled a $1.5 billion investment to support these efforts, alongside grants for renewable energy projects and infrastructure.The strategy underscores the U.S.'s geopolitical interests in securing energy partnerships and advancing nuclear technology in the region.

Critics argue that the focus on SMRs could exacerbate nuclear proliferation risks, while proponents highlight their potential to provide reliable, low-carbon energy.The move reflects broader U.S.efforts to counter Chinese influence in Southeast Asia through strategic alliances and technological collaboration.
