Extradition from United Kingdom to China: defending against a Red Notice

On paper, the United Kingdom and China have no bilateral extradition treaty. In practice, that absence does not protect anyone. A Red Notice, a diffusion, or a mutual legal assistance request can set events in motion long before a formal treaty would be needed – and the person caught in the middle often does not see it coming until they are stopped at Heathrow or a bank account is frozen without explanation.

Extradition from the United Kingdom to China is, as of mid-2025, not governed by any operative bilateral extradition treaty. However, a Chinese-requested Red Notice circulating through INTERPOL can lead to provisional arrest in the United Kingdom under domestic extradition law, and the UK courts will then determine whether surrender is lawful under their own statute. The defence turns on human-rights grounds – in particular the conditions of detention and the fairness of trial in China – as well as dual criminality and, where applicable, the political character of the underlying prosecution. Each of those grounds has real substance in this corridor, but none operates automatically.

This analysis covers the treaty position, the interaction between a Red Notice and UK extradition procedure, the grounds that have genuine traction, and the honest limits of what can be achieved – and when.

What is the treaty position between the United Kingdom and China?

No operative bilateral extradition treaty exists between the United Kingdom and China. That position has not changed. There have been diplomatic discussions over many years, but no instrument has been ratified and brought into force. The practical consequence is significant: China cannot, through a formal treaty channel, compel a UK court to consider surrender in the way that treaty partners can.

What China can do – and does – is request the circulation of a Red Notice through INTERPOL. A Red Notice is a request to locate and provisionally detain a person with a view to extradition; it is not an arrest warrant and not a judicial decision. In the United Kingdom, the decision whether to act on a Red Notice sits with the National Crime Agency and, ultimately, with the courts. Each state decides under its own law. The absence of a treaty matters at the point of surrender, but it does not prevent a provisional arrest, and it does not prevent months or years of proceedings in the interim.

In our CCF practice, we regularly see individuals who assumed that "no treaty means no risk." The risk is real. It is simply located at a different procedural point than many expect.

How does a Chinese Red Notice interact with UK extradition proceedings?

Once a Red Notice is circulated, UK authorities may act on it under the domestic extradition statute. A provisional arrest can follow. The person will then appear before a designated extradition judge, typically at the first hearing, where bail and identity are considered and a timetable is set. The extradition proceedings that follow are governed by UK extradition law, not by any bilateral instrument with China.

Because China is not a treaty partner, it falls into the category of states with which the United Kingdom has no extradition arrangement. That categorisation imposes higher evidential and procedural hurdles on the requesting state, and it shifts more analytical weight onto the UK court's human-rights review. In practice, this is one of the few areas where the absence of a treaty genuinely helps the person whose surrender is sought.

The Red Notice also has effects that are independent of the extradition proceedings. While it stands, travel is constrained. Banking relationships become difficult. Professional contracts in other jurisdictions may be suspended or terminated. Those consequences do not wait for a court to decide anything. That is why addressing the notice through the CCF and addressing the extradition request through the courts are often parallel, not sequential, processes.

In a matter involving a MENA-origin subject relocated to the United Kingdom (autumn 2024), we acted on both tracks simultaneously: a CCF file arguing data defects under the RPD's data-accuracy requirements, and a parallel submission to the extradition court on human-rights grounds. The combination produced a quicker resolution than either route alone would have done.

What human-rights defences apply in this corridor?

Human-rights grounds are the primary line of defence in UK proceedings involving a Chinese extradition request. The UK extradition statute requires the court to refuse surrender if it would be incompatible with the individual's Convention rights. In the Chinese corridor, several bases have genuine weight.

The conditions of detention in China are extensively documented by international human-rights bodies. A court considering surrender will assess whether the person faces a real risk of treatment that would violate the prohibition on torture or inhuman and degrading treatment. Article 2 of INTERPOL's Constitution requires INTERPOL's own activity to respect human rights, in the spirit of the Universal Declaration of Human Rights – a standard the CCF applies when reviewing a Chinese notice, and one that courts apply when reviewing surrender.

Fair-trial rights are equally engaged. Chinese criminal procedure does not provide procedural guarantees comparable to those required under the European Convention on Human Rights. Detention before trial can be lengthy. Access to counsel of the defendant's choosing is not assured. In our CCF practice, we have seen these concerns advanced before the Commission as grounds under the RPD's processing conditions, as well as before courts in extradition proceedings.

Where the prosecution has a political or commercial dimension – a business dispute that has been criminalised, a dispute with a state-linked entity, or an allegation that tracks a political campaign – Article 3 of INTERPOL's Constitution provides a separate ground. That provision bars INTERPOL from processing data connected to offences of a political, military, religious or racial character. The CCF applies it; the UK extradition court applies an analogous principle under the rule against extradition for political offences.

None of these grounds operates automatically. The question is always whether the evidence supports the submission. Assertion without evidence fails. Courts and the CCF require documentation: country-conditions material from reliable sources, evidence of the circumstances of the original prosecution, and analysis of why the specific individual is at risk rather than risk in the abstract.

Does dual criminality present a defence here?

Dual criminality – the requirement that the conduct alleged must constitute a criminal offence under UK law as well as under Chinese law – is a threshold condition in any extradition proceeding. In the Chinese corridor, it occasionally presents a genuine defence, though it is often not the strongest argument.

Many allegations China pursues abroad involve conduct that would, at minimum in its broadest description, correspond to something in UK criminal law. Fraud, bribery and tax-related allegations generally satisfy the test on the face of the warrant or request. But the test is not simply whether labels match. The court must be satisfied that the specific conduct alleged, properly described, would be criminal in the United Kingdom.

Where allegations are broadly drawn, or where they cover conduct that in the United Kingdom would be a civil rather than a criminal matter – a contractual dispute, an intracompany transfer, or a regulatory disagreement – dual criminality may not be made out. We have seen, in Eastern European corridor matters (spring 2025), extradition refused at first instance on precisely this basis. The same argument is available in the Chinese corridor where the facts support it. The analysis is always fact-specific.

What is the realistic prospect of resisting extradition from the United Kingdom to China?

The honest answer is that the prospects depend almost entirely on the quality of the evidence assembled, the timing of the intervention, and the specific nature of the allegations. That is true of every corridor, but it is especially true here.

The absence of a treaty is a structural advantage. The human-rights record of detention and trial in China is well documented, and courts take it seriously. Where a prosecution is politically inflected or commercially motivated, the Article 3 ground has real weight before the CCF. Where the allegations are commercially uncertain in character, dual criminality is worth examining carefully.

What does not work is a generalised argument. A submission that China has a poor human-rights record, without more, is unlikely to succeed on its own. The argument must be particularised: this individual, this prosecution, this risk. Building that case takes time, access to country-conditions evidence, and a clear understanding of what the requesting authorities have and have not disclosed.

One limit is worth stating plainly. If a first CCF request is made poorly – without the necessary evidence, without a coherent legal argument, without attention to the RPD's admissibility requirements – there is no appeal against a CCF decision, and a review requires new elements. A weak first file does not simply fail; it can make a subsequent attempt harder. We see this pattern repeatedly. It is why the quality of the initial submission matters more than the speed of the filing.

What mistakes are most commonly made in this corridor?

The most common error is treating the CCF process and the extradition proceedings as entirely separate matters to be handled sequentially. They are not. A CCF deletion of the underlying notice can affect the extradition proceedings directly. Conversely, material generated in extradition proceedings can strengthen a CCF file. The two processes should be planned together from the outset.

The second error is delay. Provisional arrest triggers statutory timelines in UK extradition law. Those timelines are short. The window to secure representation, examine the file, and prepare an effective bail application or challenge to the extradition request is measured in days, not weeks.

The third error – and the one we see most often from people who have spoken to general criminal practitioners rather than specialists – is failing to engage with the political-character ground at all. Where a prosecution has any connection to a business dispute with a state entity, a regulatory enforcement campaign, or a factional political context, Article 3 of INTERPOL's Constitution should be analysed. It is not a long shot. It is often the strongest available argument, particularly when the CCF is the forum.

The steps above are a general picture. The specific file, the requesting state's conduct, and the stage already reached determine what is actually available. That is precisely what a thorough assessment examines.

A common misconception about the Red Notice in this corridor

The most persistent myth in this area is that a Red Notice is equivalent to an international arrest warrant. It is not. It is a request to locate and provisionally detain, and each state decides under its own law whether to act on it. In the United Kingdom, acting on a Red Notice is discretionary, and the subsequent proceedings are governed by UK statute, not by INTERPOL's request.

The practical corollary is that a Red Notice can be challenged directly, at source, through the CCF – independently of, and in parallel with, any extradition proceedings in the UK courts. Deletion of the notice does not automatically end extradition proceedings, but it removes the INTERPOL mechanism and disrupts the requesting state's ability to maintain pressure through member states other than the United Kingdom. That disruption is often strategically significant.

What a Red Notice also does – and this is less often understood – is create immediate consequences that have nothing to do with courts. Banking restrictions, travel alerts, and professional-licence complications can arise the moment the notice is circulating, well before any extradition hearing. That is the dimension of exposure that feels most immediate to most of our clients: you cannot travel, bank, or sign contracts while the notice stands. Addressing it quickly, through the CCF's data-accuracy and processing requirements under the RPD, is as important as the extradition defence.

If an earlier challenge has already been made and refused – whether by the CCF or in earlier extradition proceedings – the position is more difficult but not closed. A review can identify what was missed and whether new elements are available, always remembering that there is no appeal against a CCF decision and any fresh submission must add genuinely new material.

Frequently asked questions

What happens at a first extradition hearing?

At the first extradition hearing in the United Kingdom, the court confirms the person's identity, considers bail, and sets a timetable for the substantive proceedings. It does not determine whether extradition will be ordered. However, the decisions made at this hearing – particularly on bail and on the scope of the issues to be argued – shape everything that follows. Specialist representation at this first hearing is essential; the window to act is narrow.

Can extradition be refused on human-rights grounds?

Yes. UK extradition law requires the court to refuse surrender if it would be incompatible with the person's Convention rights. In the Chinese corridor, the conditions of detention, the risk of inhuman treatment, and the absence of fair-trial guarantees are all grounds the court will examine. The argument must be particularised to the individual's specific situation and supported by reliable country-conditions evidence, not stated in the abstract.

How does the Red Notice affect the request?

A Red Notice is the mechanism through which China alerts UK authorities and other states to its interest in locating and provisionally detaining the individual. It is not a judicial decision and does not oblige any state to arrest. However, it triggers practical consequences – travel, banking and professional disruption – immediately. Challenging the notice before the CCF, on grounds under INTERPOL's Constitution and the RPD's data-accuracy requirements, can proceed in parallel with the extradition defence and often strengthens it.
