36 35 On March 11, 2026, Julien de Troullioud de Lanversin, Assistant Professor at the Division of Public Policy of the Hong Kong University of Science and Technology (HKUST), was interviewed by Science (science.org), a leading international academic journal. His analysis was featured in the special report Allegations Chinese Nuclear Blast May Reignite Weapons Testing. During the interview, Prof. Julien examined the debate over U.S. allegations that China may violate the Comprehensive Nuclear-Test-Ban Treaty (CTBT), unpacking the core reasoning behind ongoing global nuclear tensions from multiple perspectives. Prof. Julien began the discussion by comparing the historical scale of nuclear testing conducted by China and the United States. Prior to signing the CTBT in 1996, China carried out fewer than 40 nuclear tests at Lop Nur, a gure vastly lower than the more than 1,000 tests undertaken by the U.S. He argued that China’s limited track record of nuclear testing shapes its strategic calculus regarding potential low-yield nuclear tests in the future. Prof. Julien de Troullioud de Lanversin structured his subsequent arguments around two distinct dimensions: technical requirements and on-site infrastructure evidence. First, addressing technical imperatives: mainstream projections forecast that China’s nuclear warhead stockpile will expand from approximately 600 warheads to 1,000 by 2030. Low-yield nuclear testing, in his view, serves as a viable technical approach to re ne warhead designs and sustain the long-term reliability of an enlarged nuclear arsenal. Second, citing infrastructure developments backed by satellite imagery referenced in the Science article: a new laser fusion complex in Sichuan built to match the capabilities of the U.S. National Ignition Facility, alongside ongoing excavation work at the Lop Nur nuclear test site. According to Prof. Julien, the concurrent development of these two projects signals China’s pre-emptive infrastructure preparations for the possible resumption of nuclear testing.
