China has brought new entry and exit rules into effect, giving authorities wider powers to restrict overseas travel in certain cases. The regulations took effect on September 15, 2026, and focus strongly on national security and protection of sensitive technology. Chinese citizens involved in certain technology-export violations or activities considered harmful to national interests can face restrictions on leaving the country. The rules also allow some citizens who commit serious offences abroad to face exit bans after returning to China. Beijing says the measures are designed to protect national sovereignty, security and development interests.Why China Tightened Travel RulesThe new regulations expand China's ability to examine the reasons and circumstances behind international travel. Authorities can take action against people whose activities are considered a threat to industrial or technological security, particularly where export-control or technology-transfer rules are involved.
