The U.S. State Department updated its travel advisory for mainland China on October 19, 2026, adding a 'D' risk indicator that specifically warns of wrongful detention. China's overall advisory level remains at Level 2, 'Exercise Increased Caution,' but the new indicator flags it among a limited set of destinations where Washington believes U.S. citizens face an elevated risk of being detained under circumstances it considers wrongful.
According to the advisory text cited by Voice of America, the State Department has determined that Americans face a serious risk of wrongful detention in China. A department spokesperson added that the Trump administration regards the safety and security of Americans as a top priority, VOA reported.
What the advisory warns about
According to Fox News' review of the updated text, the advisory says Chinese authorities may enforce local laws arbitrarily and can impose exit bans without a fair or transparent legal process. It warns that routine professional, academic and personal activities could be treated as criminal offenses under China's broad national security laws.
The advisory also tells travelers to assume that Chinese security services can read emails, texts and social media posts sent to or from China, and it cites cases in which people were detained or deported over private messages critical of Chinese authorities, even when the messages were sent from outside the country, Fox News reported.
Exit bans can affect not only people under investigation but also their relatives, according to the advisory, and some bans have lasted years without a clear mechanism to challenge them. The State Department identifies Americans of Chinese descent, people involved in business disputes, and those with ties to U.S. law enforcement, the military, intelligence agencies or the federal government as groups facing heightened risk.
Two cases named
The State Department currently lists two Americans as formally designated wrongfully detained in China: Chen Youlin, a seismologist, and Min Zin, a scholar of Myanmar politics.
Chen, a 54-year-old American seismologist born in China, was arrested at Beijing Capital International Airport on November 5, 2024, as he prepared to board a flight to Boston, according to CBS News. He had worked on U.S.-funded research used to detect North Korean nuclear tests. Chinese authorities later accused him of espionage, according to CBS News and VOA. Secretary of State Marco Rubio designated Chen as wrongfully detained in March 2026, and President Donald Trump raised the case directly with Chinese President Xi Jinping during a May 2026 visit to Beijing, CBS News reported.
Min Zin, a scholar focused on Myanmar politics, was detained in June 2026 during a conference in Yunnan province and is accused of suspected espionage endangering China's national security, according to VOA and CBS News.
China's Foreign Ministry has rejected the wrongful-detention designation. Spokesperson Lin Jian said, as quoted by CBS News: "China is a country governed by rule of law, and the relevant department handles the case in accordance with the rule of law. There is no instance of wrongful detention."
Background and what changed
VOA reported that this marks a restoration of the wrongful-detention warning on China's advisory, which had been removed in November 2024 after three previously detained Americans were released. The new 'D' indicator replaces an earlier, broader 'O' indicator for "other" risks that had applied to China, according to Semafor, which first reported the advisory change on October 16, 2026, ahead of its formal posting on October 19.
Semafor also reported that a bipartisan group of senators introduced a resolution the previous month urging the State Department to make this specific change, and noted that the update comes despite what it described as personally warm relations between the two countries' presidents, amid continuing tensions over Taiwan, trade and artificial intelligence.
The advocacy group the James W. Foley Legacy Foundation believes at least 12 American citizens are wrongfully detained in China in total, CBS News reported, though the State Department's formal 'wrongfully detained' designation currently applies to Chen and Min.
Travel precautions suggested
Travel expert Bobby Laurie recommended that travelers to China bring stripped-down electronic devices and leave confidential information at home, according to Fox News.
