APLN Quarterly Nuclear Memo (January - April 2026)
Download the APLN Quarterly Nuclear Memo
As part of APLN’s 2026-2030 Research Strategy, we are delighted to launch a new publication, the APLN Quarterly Nuclear Memo. The document tracks, analyses and summarises nuclear developments shaping the Asia-Pacific security environment. These are grouped into four categories:
- Disruptive (developments posing acute or immediate risks to the nuclear order and regional stability),
- Stabilising (steps that reduce risk or build confidence),
- Worrisome (trends that, if unchecked, could worsen the nuclear order),
- Dialogue-based (activities that involve two or more interlocutors).

Key developments to monitor in the coming quarter include the outcome of the NPT Review Conference and its implications for Asia-Pacific non- proliferation diplomacy; the trajectory of the Iran conflict and resolution of its nuclear issue; further DPRK naval nuclear developments, including possible SLBM testing; the ROK’s pursuit of enrichment and reprocessing capabilities, as well as nuclear submarines; AUKUS submarine programme milestones; and movement on trilateral US-Russia-China arms control discussions. We will keep a close watch on these developments and more.
