The Trump administration has issued a fresh warning that Americans living in or visiting China risk “unjust arrest or detention.”
Two American scholars, Chen Youlin and U Min Zin, who traveled to China for academic and professional reasons, have been wrongfully detained, the office said, reiterating a call for their release.
“Hostage diplomacy has no place in the U.S.-China relationship,” it stated.
The State Department website last week updated its travel advisory to China, adding an explicit warning of “the risk of unjust arrest or detention.” It also included a phrase stating Beijing’s use of exit bans lacks “a fair and transparent process under the law.”
CCP ‘Can Read Your Emails’
Among the newly added paragraphs is a warning about the lack of privacy in private communication.
“Assume that China’s security services can read your emails, texts, and social media posts if you send them to or from China,” the travel advisory stated.
U.S. citizens have already been alerted to the risk of detention or deportation for sending private messages critical of Beijing or the city governments of Hong Kong and Macau. The new warning highlighted that there are cases of detentions over messages sent from outside China.
“Assume they can also read your messages if you use Chinese apps, even when you are in another country, including the United States.”
For American academics, the State Department cautioned that the CCP controls all universities and schools across the country.
“If foreign teachers or students in China express ideas contrary to what the Communist Party believes, they could be deported or detained,” the new advisory stated.

The U.S. government noted that foreigners’ religious activities in China are tightly managed by Beijing. It included a new section reminding Americans of the risks if they wish to join collective religious services, transport religious materials, or proselytize in the country.
Detention, Exit Ban
The new travel advisory highlighted that Chinese law has “an expansive definition of national security,” giving authorities a lot of freedom to determine which documents or information are “state secrets.”
“These laws and other regulations may place foreign nationals at risk for conducting routine research or handling data that is publicly or commercially available to Chinese nationals,” the warning stated. “U.S. citizens in China may face detention without information about their alleged crimes or access to U.S. consular services.”

The new travel advisory identified specific groups that may become targets of the communist regime, including those of Chinese heritage or origin, involved in business disputes with local companies, or currently or previously connected to U.S. law enforcement, the U.S. military, U.S. intelligence agencies, or other government agencies. Individuals who traveled on U.S. government-funded programs are also advised of risks of being targeted by Beijing.

The current travel advisory maintains a Level 2 warning for mainland China and Hong Kong, which asks Americans to exercise “increased caution.”
A Chinese court in August handed down a three-year jail term to Gao, accusing him of insulting “heroes and martyrs” over the artwork he crafted in the early 2000s—a ruling that drew criticism from international human rights groups and the U.S. State Department.
The House Select Committee on China said on X that the CCP has demonstrated its willingness to use “arbitrary detention and exit bans to target Americans in China.”
“Americans should take these warnings seriously,” it said on Sept. 10.
