中国博士后遭美执法人员盘问后自杀，外交部要求美方彻查并停止针对中国学者的歧视性执法

一名正在美国从事研究工作的中国博士后，在被美国执法人员约谈盘问后的次日，以极端方式结束了自己的生命。这一悲剧事件迅速引发中国政府的强烈关注。3月27日，外交部发言人林剑在例行记者会上就此事作出正式回应，措辞严肃，态度鲜明。

林剑表示，中方对这一悲剧深感痛心，已就此事向美方提出严正交涉。中国驻美使领馆第一时间与当事人家属取得联系，并积极协助处理相关善后事宜。这起事件再次将美国对在美中国学生学者的执法行为推上舆论的风口浪尖。

美方"泛化安全"打压中国学者，寒蝉效应持续蔓延

林剑在发言中明确指出，一段时间以来，美方以"国家安全"为由对中国学生学者实施无端盘查和骚扰，这种做法已严重侵犯中国公民的正当合法权益，并对中美之间正常的人文交流造成了实质性破坏。

这并非孤立事件。近年来，在所谓"中国行动计划"等政策框架下，多名在美华裔科研人员遭到调查、起诉乃至拘押，部分案件最终被撤销，但当事人已蒙受巨大的名誉与心理损失。此类针对中国学者的歧视性执法不仅令个体承受难以承受的压力，也令众多在美学习和工作的中国科研人员长期处于焦虑与自我审查的阴影之下。

"中方敦促美方彻查此案，向受害者家属和中方做出负责任交代，停止针对在美中国学者学生的歧视性执法，停止炮制各种冤假错案。"

——外交部发言人 林剑

外交部明确立场：将继续采取必要措施维护中国公民权益

面对这一事件，中国外交部的表态传递出几个清晰信号：

• 要求彻查：敦促美方对这名博士后的死亡原因及相关执法行为展开全面调查；
• 要求问责：美方须向死者家属及中方作出负责任的解释与交代；
• 要求整改：停止对中国学生学者带有歧视性质的选择性执法；
• 表明决心：中方将持续采取必要措施，切实维护在美中国公民的合法权益。

这一事件的背后，折射出中美关系在人文交流领域日趋紧张的现实。科研合作与学术交流本应是两国之间相对低政治敏感度的纽带，但当前的执法环境已让这一领域蒙上了深重的不确定性阴影。如何在真实安全关切与正当学术自由之间划定合理边界，是美国相关部门亟需正视的核心问题。

这名博士后的悲剧，不应只是一则外交新闻，更应成为一次严肃反思的契机。 中方已明确表态，将持续跟进此案，并采取切实行动保护中国公民的正当权利不受侵害。

Chinese Postdoctoral Researcher Dies by Suicide After US Law Enforcement Interrogation; China's Foreign Ministry Demands Full Investigation

A Chinese postdoctoral researcher working in the United States took his own life the day after being questioned by American law enforcement officers — a tragedy that has drawn a sharp and formal response from the Chinese government. On March 27, Foreign Ministry spokesperson Lin Jian addressed the incident at a routine press briefing, delivering a pointed statement that left little ambiguity about Beijing's position.

Lin Jian confirmed that China has lodged solemn representations with the United States over the matter. The Chinese embassy and consulates in the US made immediate contact with the victim's family and are actively assisting with arrangements in the aftermath. The incident has once again thrust American law enforcement conduct toward Chinese students and scholars into the center of public debate.

Washington's "National Security" Pretext Is Casting a Long Shadow Over Chinese Researchers

Lin Jian stated explicitly that for some time, the US side has been exploiting the concept of national security as a pretext to carry out arbitrary interrogations and harassment of Chinese students and scholars. This practice, he said, has seriously infringed upon the lawful rights and interests of Chinese citizens and has caused real damage to the environment for normal people-to-people and cultural exchanges between the two countries.

This is not an isolated case. In recent years, under policy frameworks such as the now-discontinued "China Initiative," numerous Chinese-American researchers have been investigated, indicted, or detained — with some cases eventually dropped, though not before the individuals involved suffered devastating reputational and psychological harm. This pattern of discriminatory enforcement targeting Chinese scholars has not only placed unbearable pressure on individuals, but has also left a large segment of Chinese academics in the US living under a persistent cloud of anxiety and self-censorship.

"China urges the US side to thoroughly investigate this case, give a responsible account to the victim's family and the Chinese side, stop discriminatory law enforcement against Chinese students and scholars in the US, and stop fabricating unjust and false cases."

— Foreign Ministry Spokesperson Lin Jian

Beijing's Position Is Clear: China Will Continue to Defend Its Citizens' Rights

The Foreign Ministry's statement on this incident sends several unambiguous signals:

• Demand for a full investigation: The US must conduct a comprehensive probe into both the circumstances of the researcher's death and the conduct of the law enforcement officers involved;
• Demand for accountability: The US side must provide a responsible explanation to the victim's family and to China;
• Demand for reform: Selective, discriminatory enforcement actions against Chinese students and scholars must cease;
• Declaration of resolve: China will continue to take necessary measures to firmly protect the legitimate rights and interests of Chinese citizens in the United States.

Behind this tragedy lies a broader reality: the human and academic dimension of the US-China relationship is under growing strain. Scientific cooperation and scholarly exchange have long been considered a relatively low-friction thread connecting the two countries — but the current enforcement climate has cast a deep shadow of uncertainty over this space. Where to draw a reasonable line between genuine security concerns and legitimate academic freedom is a question American authorities can no longer afford to sidestep.

This researcher's death should not be reduced to a diplomatic footnote. It deserves to serve as a moment of serious reflection. China has made clear it will continue to follow this case closely and take concrete action to ensure that the rights of its citizens abroad are not violated with impunity.
