Summary

China has begun enforcing new entry and exit rules that include restrictions on citizens considered a potential threat to national technology security. Chinese nationals who return after alleged illegal activities harming national security or interests could face a departure ban of six months to three years. Foreigners who submit false information in visa applications may be denied entry for one to five years. Taiwan says the rules could expand enforcement powers and create new risks for Taiwanese people working in high-tech industries. Beijing says the regulations provide stronger legal protection for Taiwanese people. The changes could also affect Japanese companies and travellers with business, research and supply-chain links to China. Read the full article for the wider regional and business implications.

China introduces expanded exit and entry restrictions

China on September 15 implemented new rules governing entry and exit from the country, including provisions that allow authorities to restrict the departure of Chinese nationals considered potential threats to national technology security.

The regulations, announced in July, are described by Beijing as measures targeting violations of export controls and rules governing the import and export of technology. They also establish that Chinese citizens who return after allegedly committing illegal acts or crimes overseas that harm national security or national interests may be barred from leaving China again for between six months and three years.

Foreign nationals may also face significant consequences. Individuals who provide false information during a visa application could be denied entry to China for between one and five years, according to the new provisions. The rules add to an already closely watched environment for foreign companies, researchers and professionals operating in sectors linked to technology, data and national security.

Taiwan raises concerns over high-tech workers

Taiwan, which Beijing claims as part of its territory, has advised its citizens to exercise extreme caution when travelling to China. Taiwan’s Mainland Affairs Council said on September 14 that the new regulations could effectively legalise border-control practices that previously lacked a clear legal basis while expanding the discretion available to enforcement authorities.

Taiwanese officials highlighted new references to export controls and technology import and export management. They said these provisions could create particular uncertainty for Taiwanese people employed in high-tech industries, where workers may handle sensitive information, proprietary designs or commercially important research.

Beijing rejected the criticism, arguing that the regulations offer Taiwanese people stronger legal protection. The contrasting interpretations reflect the broader political and economic tensions between the two sides, particularly as advanced semiconductors, artificial intelligence and other strategic technologies become central to national security debates.

Regional implications, including for Japan

The rules are also relevant to Japan and other economies with deep commercial links to China and Taiwan. Japanese manufacturers, technology companies and trading firms have extensive regional supply chains, while many Japanese citizens travel to China for business, research and investment. Any uncertainty surrounding exit permissions, visa declarations or technology-related activities could affect corporate risk assessments and compliance procedures.

Japan has its own significant interests in maintaining stable trade and reliable access to advanced technology. Japanese companies are increasingly strengthening supply-chain resilience by diversifying production and reviewing how sensitive information is handled across borders. The latest Chinese regulations may encourage businesses to conduct more detailed legal reviews before sending staff, equipment or technical data to China.

The measures also come amid reports from foreign governments that some of their citizens have previously been prevented from leaving China, often in cases involving security-related investigations. Chinese authorities have long imposed travel restrictions on certain government officials and executives of state-owned enterprises with access to confidential information.

Greater scrutiny for travellers and companies

For ordinary travellers, the new rules underline the importance of accurate visa applications and careful attention to local laws. For foreign companies and high-tech professionals, the changes may require stronger internal controls, clearer guidance for employees and closer consultation with legal advisers.

The practical impact of the regulations will depend heavily on how they are interpreted and enforced. Greater clarity from Chinese authorities could help reduce uncertainty, but broad language relating to national security and technology transfers may continue to concern businesses. For Japan, Taiwan and other neighbouring economies, the developments reinforce the importance of prudent travel planning, diversified supply chains and continued dialogue with Beijing.
