Curbs on personal foreign travel have long applied to senior government officials and state executives with access to confidential information.
In 2023, Reuters reported that Chinese civil servants and employees of state-linked enterprises were facing tighter limits on private travel abroad and scrutiny of foreign connections, as Beijing waged a campaign against foreign influence.
Foreign governments have also reported cases of citizens being denied permission to leave China, often due to security-related investigations.
Last month, Washington-designated Myanmar expert and US citizen Min Zin was detained after his arrest by Chinese authorities in June over accusations of endangering national security.
The US government has said the political analyst was taken into Chinese custody in Yunnan province and was held improperly.
China refuted the accusations in August, saying Min Zin was suspected of violating Chinese law.
