Our recent network activities continue to examine a range of complex global challenges, from the future of nuclear arms control and the agency of middle powers to Vietnam’s aircraft diplomacy, and more.

The inaugural issue of our Quarterly Nuclear Memo, written by Senior Research Adviser Manpreet Sethi, covers January to April 2026. The Memo assesses developments across four categories (Disruptive, Stabilising, Worrisome, and Dialogue-based) to provide a concise overview of the evolving nuclear landscape. From the expiry of New START and military strikes on nuclear facilities to preparations for the NPT Review Conference, the memo offers essential expert context for policymakers.

The inaugural APLN Membership Survey reveals how the Asia-Pacific’s most senior nuclear policy practitioners assess today’s nuclear risks. With cyberattacks on nuclear command-and-control systems identified as the greatest emerging threat, and concerns over testing resumption and the collapse of arms control frameworks also ranking high, the report underscores a pivotal period of transition for the Asia-Pacific and the broader non-proliferation regime.

In response to ROK Foreign Minister Cho Hyun’s APLN exclusive commentary that addressed the South Korean nuclear armament debate, John Carlson warns that the erosion of the international rules-based order and declining confidence in US deterrence are dangerously driving a renewed interest in the “merits” of nuclear weapons. He argues that middle powers must assert their influence to defend the NPT’s legacy while pressuring nuclear-armed states to prioritise risk reduction and disarmament. 

APLN has over 180 members from 24 countries in the Asia-Pacific.
Each week, we feature their latest contributions
