美国声称中国在2020年进行了秘密的低当量核试验,促使美国审查其暂停试验。 U.S. alleges China conducted secret low-yield nuclear test in 2020, prompting U.S. review of its testing moratorium.

美国已发布情报, 指控中国在2020年进行了一次秘密核试验, 并引述Lop Nur工地附近的小型地震事件。 The U.S. has released intelligence alleging China conducted a secret nuclear test in 2020, citing a small seismic event near its Lop Nur site. 美国官员说,数据显示发生了低当量爆炸,虽然独立专家和全面禁止核试验条约组织指出,证据没有结论。 U.S. officials say the data suggests a low-yield explosion, though independent experts and the Comprehensive Nuclear-Test-Ban Treaty Organization note the evidence is inconclusive. 中国否认这些主张,称这些主张是毫无根据的。 China denies the claims, calling them baseless. 美国正在重新考虑其为期34年的暂停试验,理由是战略竞争日益激烈,中国核武库不断扩大,目前估计有几百枚弹头。 The U.S. is reconsidering its 34-year testing moratorium, citing growing strategic competition and China’s expanding nuclear arsenal, now estimated at several hundred warheads. 两国通过模拟和次临界试验保持武库,而卫星图像显示中国正在扩大其核基础设施。 Both nations maintain their arsenals through simulations and sub-critical experiments, while satellite imagery shows China expanding its nuclear infrastructure.
