China’s new exit and entry-related rules tied to national security and certain technology activities take effect, according to reporting from multiple outlets. The measures include limits on departures for citizens who are accused or found to have committed conduct abroad deemed to harm national security or China’s interests.

One rule allows authorities to impose exit bans of up to three years on citizens returning to China after committing illegal or criminal acts abroad that are considered to affect national security or interests. Other provisions also address the role of false information in travel documentation: foreign nationals may be denied entry for one to five years if visa applications contain false statements. Outlets characterize the package as part of a broader tightening of controls linked to national security, with specific consequences varying by conduct and citizenship status.
