周二晚间，一位美国高级官员披露了关于中国在2020年6月据称进行核炸弹试验的新细节。
美国国务院助理国务卿克里斯托弗·姚（Christopher Yeaw）周二在华盛顿特区哈德逊研究所的活动中表示，爆炸的证据来自哈萨克斯坦的一个地震台站。该台站于2020年6月22日探测到中国罗布泊试验场发生了2.75级爆炸。
“从那以后我查看了更多数据。我认为这几乎不可能是其他事件，只能是一次爆炸，一次单独的爆炸，”姚说，并补充说数据与采矿爆破不一致。
“这也完全不符合地震的特征，”他补充道，“这……正是你预期的核爆炸试验的结果。”

中国驻华盛顿大使馆拒绝了特朗普政府的指控，告诉美国全国广播公司新闻（NBC News）称该报道是“政治操纵”，并指责美国“逃避自身核裁军责任”。
“中国敦促美国重申五个核武器国家关于不进行核试验的承诺，维护全球反对核试验的共识，并采取具体步骤维护国际核裁军和不扩散制度，”发言人刘鹏宇对该媒体表示。
美国官员警告称，北京可能正在准备“数百吨当量”规模的试验——这一规模凸显了中国加速核现代化进程，并使将北京纳入军备控制谈判的努力复杂化。

负责军控与国际安全事务的国务院副部长托马斯·迪南诺（Thomas DiNanno）最近表示，美国政府有证据表明中国在其罗布泊基地进行了核爆炸试验。
“我可以透露，美国政府知道中国进行了核爆炸试验，包括准备进行数百吨当量的指定试验，”迪南诺在联合国裁军会议上发表讲话时表示。
他补充道：“中国在2020年6月22日进行了一次此类产生当量的核试验。”

迪南诺还指责北京使用“解耦”——以抑制地震信号的方式引爆装置——来“向世界隐瞒其活动”。

中国外交部否认了这些指控，指责华盛顿将核问题政治化，并重申北京自愿暂停核试验。
这一指控加剧了关于核查、威慑以及在美国重新陷入大国核竞争的时代，美国依赖先进模拟而非实弹试验的核武库管理项目是否足够的疑问。

Mysterious 2020 explosion in China had hallmarks of nuclear test, US official alleges
US official says seismic station in Kazakhstan detected magnitude 2.75 explosion at China’s Lop Nur test grounds

A senior U.S. official offered new details Tuesday night about an alleged nuclear bomb test conducted by China in June 2020.
Assistant Secretary of State Christopher Yeaw spoke at a Hudson Institute event in Washington, D.C., on Tuesday, and said evidence of the explosion came from a seismic station in Kazakhstan. The station detected a magnitude 2.75 explosion located at China’s Lop Nur test grounds on June 22, 2020.
“I’ve looked at additional data since then. There is very little possibility I would say that it is anything but an explosion, a singular explosion,” Yeaw said, adding that data was not consistent with mining detonations.
“It’s also entirely not consistent with an earthquake,” he added. “It is… what you would expect with a nuclear explosive test.”

China’s embassy in Washington has rejected the Trump administration’s claim, telling NBC News that the report is “political manipulation,” and the U.S. is “evading its own nuclear disarmament responsibilities.”
“China urges the U.S. to reaffirm the five nuclear-weapon states’ commitment on refraining from nuclear tests, uphold the global consensus against nuclear tests, and take concrete steps to safeguard the international nuclear disarmament and non-proliferation regime,” spokesperson Liu Pengyu told the outlet.
U.S. officials warned that Beijing may be preparing tests in the “hundreds of tons” range — a scale that underscores China’s accelerating nuclear modernization and complicates efforts to draw Beijing into arms control talks.

Thomas DiNanno, undersecretary of state for arms control and international security, said recently that the United States has evidence China conducted an explosive nuclear test at its Lop Nur site.
“I can reveal that the U.S. government is aware that China has conducted nuclear explosive tests, including preparing for tests with designated yields in the hundreds of tons,” DiNanno said during remarks at the United Nations Conference on Disarmament.
He added, “China conducted one such yield-producing nuclear test on June 22 of 2020.”

DiNanno also accused Beijing of using “decoupling” — detonating devices in ways that dampen seismic signals — to “hide its activities from the world.”

China’s foreign ministry has denied the allegations, accusing Washington of politicizing nuclear issues and reiterating that Beijing maintains a voluntary moratorium on nuclear testing.
The accusation has sharpened questions about verification, deterrence and whether the U.S. stockpile stewardship program — which relies on advanced simulations rather than live detonations — remains sufficient in an era of renewed great-power nuclear competition.
