China exit rules tightened to guard rare earth, battery secrets

Starting September 15, 2026, China will implement a set of revised, more stringent exit and entry regulations crafted to address two pressing policy priorities: preventing unauthorized leakage of sensitive industrial knowhow by veteran technical personnel, and managing travel to nations classified as “high-risk” by Beijing. The 19-article regulatory framework, formally announced by the State Council on July 31, establishes a unified cross-agency system for overseas risk alerts, enhanced scrutiny of travel purpose for all exit-entry applications, and tighter oversight for both Chinese citizens and foreign nationals entering or leaving the country.

Under the new rules, immigration and visa authorities gain expanded authority to interview applicants and request supporting documentation or data to confirm travel purposes and identity. Issuers of formal invitation letters for foreign visitors will now bear legal responsibility for the authenticity of the information they provide. A key provision grants commerce departments the power to issue exit bans for Chinese citizens found to be violating export control or technology trade regulations, or those deemed likely to threaten national industrial or technological security. For travelers heading to high-risk destinations, border and travel document officials are required to issue official warnings advising caution, and may actively discourage travel to areas categorized under the highest risk level. Chinese citizens who commit national security-related offenses overseas face exit bans ranging from six months to three years following their return to China. All exit bans require formal written notification to the affected individual, including disclosure of underlying facts, legal justifications, and appeal channels — except in cases where notification would compromise ongoing national security investigations or criminal probes. Exit-entry intermediary service providers are also mandated to register with local immigration authorities within 15 days of establishment, with all staff registered through their employing companies; existing agencies must complete registration within 90 days of the regulation taking effect.

While the export control provision does not explicitly name targeted industrial sectors, Chinese policy analysts note it aligns with existing restrictions Beijing has already imposed on strategically critical sectors, including electric vehicle batteries, solar panel technology, and rare earth processing. Legal scholar Cheng Xiezhong, a professor at the China University of Political Science and Law, explained that the framework intentionally avoids an exhaustive list of potential threats, given the broad scope of risks to national security and interests. “The new regulation explicitly names one clear high-risk scenario: violation of export control or technology trade management regulations,” Cheng noted. He added that unauthorized transfers of dual-use technologies or core industrial expertise to overseas entities will fall under the “harm to national security and interests” clause outlined in Article 12 of the new regulation.

A Shandong-based columnist writing under the pen name Xinghe Duke pointed to the phrase “may endanger” as a core defining element of the new policy. “This means authorities will not wait for tangible harm to occur before taking precautionary action,” he explained. “The wording specifying that restrictions are decided by commerce and relevant departments confirms the process follows formal legal procedures. An exit ban is not an arrest; it only prohibits the targeted individual from departing the country at this time.”

Xinghe Duke further connected the new regulation to the State Council’s Regulations on Overseas Investment, which entered into force on July 1, 2026. That earlier rule bars investors from transferring export-controlled goods, technology, services, or data through personnel deployments, overseas work arrangements, technical guidance, or cross-border training programs. He emphasized that engineers holding expertise in core technologies — including EV battery electrolyte formulas, N-type solar cell production technology, and rare earth separation processes — are the primary targets of the new exit-entry rules.

“Previously, foreign firms evaded China’s export controls by poaching Chinese engineers with higher salaries, permanent residency, and equity to build duplicate production facilities in Vietnam, India, or Mexico,” Xinghe Duke said. “That route is now closed under the new regulatory framework.” He added that ongoing rare earth separation projects in Australia (backed by U.S. and Japanese firms) and Texas have depended on recruiting experienced Chinese technical personnel to overcome purity production bottlenecks.

The policy shift follows a series of escalating trade and technology tensions dating back to 2025. When the Trump administration launched a global trade war targeting China in April 2025, Beijing retaliated with export restrictions on critical minerals, separation equipment, and purification technology bound for the U.S. Similar restrictions were imposed on Japan after Japanese Prime Minister Sanae Takaichi made pro-Taiwan statements last November. As the U.S., Japan, and EU work to build alternative rare earth supply chains in Australia, Brazil, and across Africa, they have increasingly turned to recruiting Chinese industry veterans to launch their projects, prompting Beijing to ramp up efforts to stem talent and technology outflows in recent months.

Chinese state media reported in June 2025 that a wave of senior executive resignations at state-owned rare earth producers had drawn regulatory scrutiny, noting that experienced industry professionals had become prime recruitment targets for foreign entities. In response, authorities already rolled out a series of pilot restrictions in select regions: three-year post-resignation bans on senior technical staff taking roles with competing overseas firms, digital watermarking for internal company documents that triggers automatic alerts if copied overseas, mandatory advance reporting to company party organizations for core staff whose children plan to study abroad, and advance travel application requirements for family members of key technical personnel.

In April 2026, China’s Ministry of State Security publicly disclosed details of a 2023 espionage case in which a manager surnamed Cheng at a Chinese rare earth company was sentenced to 11.5 years in prison for leaking state secrets to an employee of a foreign nonferrous metals firm. Cheng made frequent trips abroad and accepted roughly $510,000 in bribes, which he used to cover living expenses for his wife and daughter who resided overseas.

Industry observers note that prior pilot measures had notable gaps that the new exit-entry regulation addresses. Previously, authorities could only block departure for individuals already involved in an active criminal investigation; retirees and resigned employees had no legal obligation to disclose travel plans, as long as they were not formally employed by a foreign firm. These loopholes are widely seen as a key driver behind Beijing’s decision to implement broader, more systemic exit-entry restrictions.

Beyond technology security, the regulation also includes provisions governing travel to high-risk countries. Some Chinese legal experts frame the high-risk travel provisions as a consumer protection measure, designed to help Chinese travelers avoid falling victim to transnational scam networks or entering active conflict zones. “The regulation requires Chinese foreign affairs and culture and tourism authorities to issue timely security alerts and travel risk warnings based on conditions including war, armed conflict, public safety threats, natural disasters, and disease outbreaks,” explained Guo Yongliang, deputy dean and professor at the School of Foreign-Related Security at the China People’s Police University. “It also mandates that immigration officials warn travelers heading to high-risk destinations to exercise caution during the travel document application and border clearance processes.”

However, observers have noted that China’s travel warning system has also been used to exercise diplomatic pressure. After Prime Minister Takaichi’s pro-Taiwan remarks in November 2025, China’s Ministry of Foreign Affairs and Ministry of Culture and Tourism issued an official advisory urging Chinese citizens to avoid travel to Japan. In mid-2026, Chinese travel agencies reportedly began planning to resume sales of Japanese tour packages, but Chinese authorities quickly halted the plan.

Data from the Japan National Tourism Organization shows that roughly 2.06 million Chinese mainland tourists visited Japan in the first half of 2026, a 56.4% year-on-year decline. Even with the drop, average monthly arrivals hit 340,000, most of which are independent travelers rather than organized tour groups. Policy analysts say the new exit-entry regulation gives Beijing additional administrative tools to discourage Chinese travel to Japan, as a means of increasing political pressure on Tokyo.
