China's new exit-and-entry rules came into effect on Tuesday, granting authorities explicit legal power to prevent citizens from leaving the country if they are considered a potential threat to national technology security or are involved in violations related to export control or technology transfer. These regulations also aim to curb wealth and talent outflows, intensifying pressure on wealthy households, private bankers, trust companies, and immigration agencies that facilitate the movement of money and families abroad. This move transforms a series of ad hoc travel bans into a permanent mechanism to stem capital and talent flight, both of which are crucial for Beijing's innovation and economic growth initiatives.

The new rules specifically target technology professionals, providing a legal basis to enforce existing export-control and counter-sanction regimes at the border. Private bankers aiding wealthy Chinese clients with offshore money movement are already experiencing changes in behavior, with some being questioned at border checkpoints and rebranding events to avoid scrutiny. Some bankers now travel to China without sensitive documents, sending them separately to avoid potential customs checks that could expose client financial data. A provision under the new rules also prohibits foreign companies from offering exit-entry immigration services within mainland China and requires registered agencies to report public-sector employees and military personnel seeking foreign nationality or overseas permanent residency.

Furthermore, the framework strengthens local authorities' ability to restrict departures by individuals who are believed to owe tax on offshore wealth. This comes after China imposed a 20% income tax on assets moved into offshore trusts since 2023, closing a loophole used for asset protection and succession planning. The tightening of these rules is seen by critics as a way to enhance Beijing's control over its citizens' activities abroad, with some analysts noting a significant increase in the number of exit bans recorded in China's supreme court database in recent years, despite official denials that the rules restrict the travel of "ordinary citizens."
