China has tightened its border rules – again – but for foreign journalists, executives and researchers, the bigger concern should be legislation already on the books.

The country may be easy enough to enter for now. Getting back out is another matter altogether.

A new State Council regulation on exit and entry administration took effect this week, tightening rules around national security, technology and immigration. Beijing, as might be expected, says the measures are designed to protect travellers, safeguard national security and help regulate cross-border movement – legal speak.

But with the power to stop foreigners entering - and leaving - China already in place, a new decree only strengthens it.

Under Article 28 of China's Exit and Entry Administration Law as is, foreigners can be prevented from leaving in circumstances including criminal cases, unresolved civil litigation and unpaid labour claims. The law also contains a broader provision covering other circumstances whereby Chinese laws or administrative regulations prohibit departure.

As a result, Britain's government now warns that foreign nationals can face exit bans lasting months or years and may not know one has been imposed until the very moment they try to leave China.

The bans can arise from something as simple as commercial or private disputes reported to the government, investigations involving an individual, their family or even their employer, in addition to civil and / or criminal matters.

This has seen British nationals and others detained against their will, while authorities can withhold passports, impose an exit ban or detain suspected ‘offenders’ for up to 37 days without charge.

In essence, for anyone caught in the system, the airport can become the first and worst possible place to discover a legal problem even exists.

Journalists face a different risk

For foreign reporters meanwhile the concern is less that writing one bad story automatically triggers an airport ban and more that reporting on ‘sensitive’ matters can bring them into contact with China's far-reaching national-security laws.

The UK Foreign Office, for one, warns that the concepts of national security and national interest have a broad scope in Chinese legislation. It says foreign nationals can be detained over alleged national-security offences, including for activity conducted outside China’s borders, including for online activity.

If identified, those detained on national-security grounds can be held for up to six months before any formal arrest proceedings are undertaken, with restrictions known to be in place in China on legal representation before charges are brought.

British officials also warn that people linked to foreign governments, media organisations and NGOs may face greater surveillance, harassment or detention. The surveillance aspect of London’s diplomatically worded missives is already a well known occurrence.

Sensitive reporting can and does include coverage of topics such as the People's Liberation Army (PLA), Taiwan and any reports related to the self-governing island nation off China’s east coast, East Turkestan – known as Xinjiang in China – Tibet, Hong Kong independence efforts or activists and the Communist Party leadership.

China's increasingly oppressive approach to political dissent and ethnic minorities in recent years in ‘Xinjiang’ and Tibet has made those subjects particularly sensitive for Beijing.

As is, Britain's current guidance says journalists reporting on politically sensitive issues or areas can face harassment, monitoring, intimidation by authorities, threats and physical attacks.

That does not mean a journalist writing about such will automatically be detained or barred from leaving, although it does mean the risks surrounding such reporting are very real and potentially physically dangerous.

China has form

Bloomberg news assistant Haze Fan was detained in December 2020 by Chinese authorities on suspicion of national-security violations. Chinese officials said at the time that she was suspected of violating national-security laws – a vague catch-all used in multiple known cases.

In another case, Cheng Lei, an Australian citizen and former CGTN business presenter, was detained in August 2020 and detained after being convicted of providing state secrets overseas. She was only released in October 2023. Min Zin, a US citizen and scholar, is a current case with AP reporting he was detained in China in June 2026 on suspicion of endangering national security. Elsewhere, the Wall Street Journal found 37 cases involving foreign nationals hit with exit bans in an online Chinese court database, but said lawyers believed the real number was substantially higher and that academics had identified more than 150 cases.

In 2025, the Washington Post reported that at least several dozen Americans were under Chinese exit bans, according to experts and former officials.

Reuters has also documented a series of cases involving foreign executives caught up in Chinese investigations and travel restrictions, including a Wells Fargo employee who was barred from leaving China although in September 2025 it was reported that the same Wells Fargo banker had subsequently been allowed to return to the US; the Chinese Foreign Ministry saying at the time that the exit ban was related to her involvement in a criminal case.

And these are only the cases known to involve westerners or news agencies.

The lesson though is uncomfortable and simple: an exit ban does not necessarily require a Hollywood-style espionage case. A civil dispute with a neighbour can be enough.

And in some cases the person affected may not know that the restriction even exists until they try to leave.

What has changed?

This is where the new September 15 regulation matters.

The State Council's 19-article regulation, issued in July and now in force, establishes or clarifies restrictions covering Chinese citizens and foreign nationals in different circumstances.

For Chinese citizens, it provides for restrictions on departure involving issues including illegal exit or entry, overseas criminal activity deemed harmful to national security or interests, and violations of export-control or technology-import and export rules that could threaten China’s industrial or technological security.

For foreigners, the new decree is held up primarily as relating to entry and as such allows authorities to deny entry to people who provide false materials or statements in visa applications or at the border, as well as those falling within specified, but hard to confirm categories, under Chinese law. But in terms of real-world freedoms, the existing exit-ban and how the new decree may be used in this regard is the bigger issue.

Why the tech angle matters

An important factor is that the new rules arrive as Washington and Beijing remain locked in a strategic and well publicised battle over semiconductors and artificial intelligence (AI).

That makes the language around industrial and technological security particularly significant for any company executives, researchers or journalists working in sensitive sectors.

At present, there is no black and white evidence that a western journalist who has published an unfavourable story about a Chinese semiconductor company has been stopped at the airport. Chinese authorities rarely operate in such clearly defined colours, however.

The risk is that a separate investigation, dispute or ‘alleged’ – not even proven – offence could bring an individual within China's existing national-security or exit-ban framework.

For foreign businesses, meanwhile, the potential exposure is more immediate: civil disputes and open investigations can already result in restrictions on leaving China. This is well documented.

Xinjiang, Taiwan, Tibet and the reporting problem

China's approach to Xinjiang and Tibet, perhaps a lesser degree to Taiwan given its international standing and recognition, is another reason foreign journalists need to understand the distinction between ordinary reporting and politically sensitive activity.

Britain warns that foreigners travelling in or around sensitive areas controlled by China can attract additional attention, including when taking photos, engaging with political groups or charities, or interacting with ethnic-minority communities. Whilst this does not include Taiwan per se, in Xinjiang, Britain's current guidance refers to widespread arbitrary arrests and extrajudicial detention affecting local people, particularly the Uyghurs local to the region, and other ethnic minorities.

In Tibet, foreign visitors require permits and must travel on organised tours, sources say.

This in turn means that while not every foreign visitor is seen as a potential detainee, it makes clear the willingness of China's security apparatus, and treats certain subjects and locations very differently from ordinary tourist destinations in Beijing and Shanghai.

Hong Kong

To some extent, Hong Kong should not simply be folded into the same legal category as mainland China even if independence activists in the former British outpost are currently languishing in jail for their role in anti-government demonstrations.

At present, Hong Kong still has its own immigration system and national-security legislation – at least on the surface.

But while Beijing's political control over the territory has tightened significantly, and Hong Kong has its own expanding national-security framework in place, how long will it be before the immigration norms seen elsewhere in China are imposed in Hong Kong?

The Hotel California crossover

China needs foreign tourists, capital, expertise and most of all business. As big as its economic clout is, Beijing recognises the need to interact with the outside world.

At the same time, it wants tighter control over information, technology, political activity and national-security risks. And in the eyes of China, those objectives can coexist. Until they don't.

For years, the nightmare scenario for a foreign correspondent was losing access to China: a visa refused, an accreditation withdrawn or a future application rejected. It has happened on many occasions.

The more serious possibility at present, however, is being inside the country when the problem occurs. In this regard, foreign governments are quite rightly starting to warn that foreign nationals can be subjected to exit bans and that the restriction may only become apparent when they attempt to leave.

Chinese authorities would of course reject any suggestion that the system is arbitrary, pointing instead to formal legal procedures and avenues of appeal. But when dealing with outsiders, China’s logic can sometimes become circular: the route to challenging the restriction leading back to the same departure lounge where the attempt to leave began.

To this end, the regulation itself says people subject to an exit prohibition should receive written notification setting out the facts, reasons, legal basis and available remedies. The key word here is ‘should’. Authorities can also withhold that notification if they believe disclosure could affect national security or a criminal investigation.

But a remedy on paper and a remedy that can be exercised quickly are not necessarily the same thing, particularly in such authoritarian states as China. Especially when you are standing at an airport gate, passport in hand with a plane waiting on the other side of the border.

That is where the Hotel California comparison becomes hard to resist.

You can check in. You can do business. You can report. You can investigate.

But if Chinese law gives the authorities grounds to stop you leaving, your return flight may suddenly become irrelevant. If you have in some way, shape or form been deemed to act in ways detrimental to the vague concept of national security claims or have ‘hurt the feelings of the Chinese people’ – a longstanding phrase used against foreigners in official diplomatic language since at least 1959 – your trip home may end before it has even begun.

The Eagles' famous line — “you can never leave” — was never intended as a warning about Chinese immigration law. As a metaphor in 2026 though, if the shoe fits …...
