China’s intelligence agencies are led by the civilian Ministry of State Security, which handles foreign espionage and counterintelligence, and are joined by the Ministry of Public Security for domestic and extraterritorial policing, three People’s Liberation Army arms created in a 2024 restructuring, and the Chinese Communist Party’s United Front Work Department for influence operations abroad. A web of national security laws requires every Chinese citizen and organization to assist these agencies when asked, with penalties for espionage that reach up to the death penalty.
Ministry of State Security
The Ministry of State Security (MSS) is the closest Chinese equivalent to a combined CIA and FBI. It was established in 1983 by the National People’s Congress to counter subversion and sabotage, and it handles foreign intelligence collection, domestic counterintelligence, and the protection of state secrets.1Federation of American Scientists. Ministry of State Security History It reports to the State Council and is currently led by Minister Chen Yixin. A former FBI estimate put its personnel around 800,000.
The MSS has powers that go well beyond investigation. In suspected espionage or state-secret cases, it can place people under “residential surveillance at a designated location,” a form of incommunicado detention lasting up to six months at an undisclosed site, without access to a lawyer or family.2Wikipedia. Ministry of State Security (China) The power applies to Chinese citizens and foreign nationals alike.
In January 2024, the MSS publicly listed ten categories of behavior that trigger a national-security investigation, including suspected involvement in crimes compromising state security, illegal possession of classified materials, refusal to cooperate with anti-espionage inquiries, and unauthorized activities in designated security zones.3ECNS. China’s Ministry of State Security Unveils 10 Investigation Triggers The list was read as a signal that the ministry intended to be more visible and more aggressive against both domestic and foreign targets.
Ministry of Public Security
The Ministry of Public Security (MPS) is the national police force. It oversees traffic enforcement, organized crime, cybercrime, and political stability, and its officers staff public security bureaus at the provincial, municipal, county, and neighborhood levels.4Ministry of Public Security of the People’s Republic of China. Public Security for a Safer China Within the ministry, the First Bureau focuses on political security and monitoring domestic dissent, and its director typically rises to vice minister.
MPS databases track citizens considered potential risks to social order, monitoring travel, online activity, and associations. That interest follows Chinese nationals when they live or travel abroad.
Overseas Police Stations
Starting in 2014, local public security bureaus began setting up so-called “110 Overseas” stations in foreign countries, named after China’s emergency police number. Officially they help overseas Chinese renew driver’s licenses and deal with local police. By late 2022, at least 54 stations had been identified in 30 countries, many operated by bureaus in Fujian Province.
Multiple governments have accused the stations of pressuring Chinese dissidents and criminal suspects abroad to return home, at times by threatening relatives in China. In October 2022, U.S. authorities raided a station in New York City linked to the America Changle Association. Several host countries have opened investigations or demanded closures.
Operation Fox Hunt and Sky Net
The MPS also runs extraterritorial enforcement through Operation Fox Hunt, launched in 2014, and a broader companion effort called Sky Net. These programs target Chinese officials and businesspeople accused of financial crimes who have fled abroad, and by the programs’ own count have led to the return of more than 8,000 people. Undercover teams enter foreign countries under false pretenses, recruit local accomplices, and use threats against relatives still in China to pressure targets into returning.
PLA Intelligence After the 2024 Restructuring
The People’s Liberation Army overhauled its intelligence architecture in April 2024. The Strategic Support Force, which had consolidated space, cyber, and electronic warfare since 2015, was dissolved and replaced by three arms, each reporting directly to the Central Military Commission.5T2COM G2 Operational Environment Enterprise. China Introduces People’s Liberation Army-Information Support Force
- The Information Support Force (ISF) handles strategic information and communications support across the PLA, centralizing technical intelligence collection and feeding strategic intelligence to theater commands.6U.S. Department of Defense. 2025 Annual Report to Congress
- The Aerospace Force (ASF) handles space-based intelligence, reconnaissance, and counterspace operations, carved out from the former Aerospace Systems Department.
- The Cyberspace Force (CSF) runs offensive and defensive cyber operations, evolved from the former Network Systems Department.
Xi Jinping personally attended the ISF’s establishment ceremony, a sign that the change reflected dissatisfaction with how the old Strategic Support Force had integrated information support across services.
Separately, the Joint Staff Department’s Intelligence Bureau, formerly the General Staff Department’s Second Department and long known as 2PLA, continues to compile, analyze, and disseminate intelligence for military command at every level. The ISF and its sister arms focus on collection; the Intelligence Bureau fuses that data into assessments for operational commanders.
United Front Work Department
The United Front Work Department (UFWD) has no clean Western equivalent. It runs engagement, influence, and intelligence operations on behalf of the CCP, working in parallel to the foreign ministry and the MSS.7Select Committee on the CCP. United Front 101 Memorandum It reports to the Party’s Central Committee, and subordinate departments sit inside provincial party committees, companies, research institutes, and universities.
Abroad, the UFWD targets foreign universities, think tanks, civic groups, and prominent individuals to shape perceptions of China. It uses ostensibly independent voices to promote favorable narratives, monitors diaspora communities through co-opted overseas Chinese associations, and works to neutralize critics. The department also plays a direct role in technology acquisition, pressuring foreign companies operating in China through united front organizations embedded within joint ventures.7Select Committee on the CCP. United Front 101 Memorandum
In 2023, U.S.-based groups tied to united front organizations mobilized protesters against Taiwan’s president during her transit through the United States. In another case, a civic association co-opted by the UFWD operated a covert police station in New York. The department also builds intelligence databases on the Uyghur diaspora and mobilizes overseas groups to counter international criticism of CCP policies in Xinjiang.
The Laws That Compel Cooperation
China’s intelligence agencies operate inside a set of overlapping laws that impose broad obligations on citizens, organizations, and foreign companies.
National Intelligence Law
The National Intelligence Law, adopted in June 2017 and amended in April 2018, sets the overarching mandate. Article 7 states that “all organizations and citizens shall support, assist, and cooperate with national intelligence efforts in accordance with law, and shall protect national intelligence work secrets they are aware of.”8China Law Translate. PRC National Intelligence Law (as Amended in 2018) Private companies and individuals must provide assistance when asked.
A nuance often missed: the Intelligence Law’s own penalty chapter does not spell out punishments for refusing to cooperate. Penalties instead apply when someone actively “obstructs” intelligence work, routing enforcement through the Criminal Law (Article 277, obstruction of government officials) and the Public Security Administration Punishments Law. The line between “not cooperating” and “obstructing” is whatever the investigating agency says it is.
Counter-Espionage Law
The Counter-Espionage Law, substantially amended in 2023, broadened the definition of espionage well beyond traditional spying. It now covers stealing or providing “documents, data, materials, or items related to national security” to any foreign organization, not just foreign intelligence services, and it explicitly includes foreign-linked cyberattacks against government agencies or critical infrastructure.9China Law Translate. Counter-Espionage Law of the P.R.C. (2023 ed.)
With approval from a city-level or higher security official, MSS agents can inspect electronic equipment, read and collect documents and data, and require cooperation from relevant people and organizations.9China Law Translate. Counter-Espionage Law of the P.R.C. (2023 ed.) There is no independent judicial review. Foreign businesses have flagged the phrase “items related to national security” as especially alarming, since routine commercial data could arguably fall inside it.
Criminal Penalties
The Criminal Law sets the actual sentences. Joining an espionage organization or accepting its assignments carries ten years to life, with a three-to-ten-year range for less serious cases. Stealing, spying on, or illegally providing state secrets to a foreign entity carries five to ten years, or ten years to life for especially serious circumstances. Espionage causing extremely grave harm to the state can be punished by death.10Supreme People’s Procuratorate. Criminal Law of the People’s Republic of China – Chapter II
Data Security and Cross-Border Data Rules
The 2021 Data Security Law requires anyone processing data in China to build security management systems, run regular risk assessments for “important data,” and cooperate with public security or national security agencies seeking data for investigations.11Supreme People’s Procuratorate. Data Security Law of the People’s Republic of China No organization or individual may provide data stored in China to a foreign judicial or law enforcement authority without Chinese government approval.
As of January 2026, cross-border data flows sit inside a layered framework built on the Cybersecurity Law, the Data Security Law, and the Personal Information Protection Law, plus an administrative regulation and four implementing rules. Companies classed as “Critical Information Infrastructure Operators” must store qualifying data in China and pass a security assessment before any of it leaves the country.
How China Collects Intelligence
Talent Plans and Non-Traditional Collectors
A distinctive feature of China’s approach is the systematic use of people who are not professional spies. Students, academics, business executives, and researchers are recruited to gather information that formal agents could not reach. The FBI identifies “talent plans” as a primary vehicle: China recruits science and technology professionals, regardless of citizenship, and signs them to contracts with Chinese universities or government-affiliated companies.12Federal Bureau of Investigation. Chinese Talent Plans
These contracts typically require participants to submit to Chinese law, share new technology developments exclusively with China (often without telling their U.S. employer), and recruit colleagues into the same program. Participants keep their existing jobs and their ongoing access to intellectual property, pre-publication research, and government-funded projects. The programs have produced information on military technologies, nuclear energy, wind tunnel design, and advanced lasers.12Federal Bureau of Investigation. Chinese Talent Plans
Cyber and Signals Intelligence
Specialized teams inside the MSS and the PLA’s Cyberspace Force work to breach the networks of foreign governments and private companies. Targets range from defense contractors and technology firms to pharmaceutical companies and critical infrastructure operators, with stolen data often including intellectual property, trade secrets, and strategic plans. Signals intelligence efforts focus on intercepting the communications of foreign defense forces to read strategic intentions and spot military movements early. The 2024 restructuring gave cyber and signals collection more organizational independence by placing the Cyberspace Force and the Information Support Force directly under the Central Military Commission.
What This Means for Foreigners in China
One enforcement tool that catches many foreigners off guard is the exit ban. Chinese authorities can prevent anyone from leaving the country during criminal investigations, civil and commercial disputes, or national-security cases. A 2018 amendment to the Supervision Law allows bans on people merely connected to an investigation, not just direct suspects, and most people discover the ban only when they try to board a flight or cross a border.
Bans can last for months or years while proceedings run. In one documented case, siblings were kept from leaving for three years because the ban related to their father’s legal situation, though they faced no personal charges. In a recent year, courts issued roughly 53,000 exit bans, nearly all in civil rather than criminal cases. The Dui Hua Foundation estimates that between 30 and 40 U.S. citizens are unable to leave China at any given time, and considers that figure an undercount.
