China using 'hostage diplomacy' to pressure foreign governments: Report
Synopsis
A detailed report by Safeguard Defenders founder Peter Dahlin — himself a former victim of Chinese detention — argues that Beijing is systematically using foreign nationals held under its opaque 'Residential Surveillance at a Designated Location' system as geopolitical pawns. The cases already public, spanning Czech, US, British, and Japanese nationals, may be only the tip of the iceberg.
Key Takeaways
A report by Safeguard Defenders founder Peter Dahlin documents a pattern of China detaining foreign nationals as diplomatic leverage, labelled 'hostage diplomacy' .
Documented cases include a Czech citizen , two US citizens , a British citizen , two Japanese businessmen , and a Chinese journalist whose whereabouts remain unknown.
Detainees are held under Residential Surveillance at a Designated Location (RSDL) , described by critics as enforced disappearance with no access to lawyers or family.
Dahlin, a former RSDL victim, argues the publicly known cases are 'only the tip of the iceberg' of actual detentions.
The Chinese Communist Party (CCP) is reportedly broadening RSDL use against foreigners, particularly when the detainee can serve as a foreign policy tool.
Beijing's detention of foreign nationals has revealed an increasingly systematic pattern of using citizens as geopolitical leverage — a practice that experts and rights groups are now explicitly labelling 'hostage diplomacy', according to a detailed report published on 14 November 2026. The findings suggest that the cases already on record may represent only a fraction of the actual scale of such detentions by Chinese authorities.
Key Allegations in the Report
Peter Dahlin, founder of rights NGO Safeguard Defenders and a former victim of Chinese detention, laid out a stark catalogue of cases in a piece published in The Diplomat. Among those documented: a Czech citizen reportedly taken by Chinese police or the Ministry of State Security (MSS) to pressure the Czech government into releasing an alleged Chinese spy; a US citizen lured into the country and then seized by the MSS; and another US citizen who has since been moved into formal arrest.
Dahlin also cited a British citizen whose release from prison was only recently made public, two Japanese businessmen working in the sensitive field of rare earth materials, and a Chinese journalist whose whereabouts remain unknown. The list extends further to include Chinese lawyers, journalists, and NGO workers who have all, he argues, been subjected to enforced disappearance.
The RSDL System: Disappearing Into Legal Limbo
All the individuals referenced in the report share a common experience — they were not simply arrested but effectively vanished into a system that Chinese authorities describe as 'Residential Surveillance at a Designated Location' (RSDL). Critics and human rights organisations widely regard RSDL as a mechanism for enforced disappearance, stripping detainees of access to legal counsel and family contact while evading formal criminal procedure.
Dahlin, who has personal experience of the system, noted the deliberate ambiguity: 'They were not simply detained or arrested but disappeared into what Chinese authorities euphemistically describe as residential surveillance at a designated location,' he wrote.
A Growing Trend, Not Isolated Cases
The report argues that the diversity of targets — spanning nationalities, professions, and contexts — reflects how the Chinese Communist Party (CCP) is broadening the application of RSDL as a foreign policy instrument. What was once a tool used sparingly, and sometimes deniably, against foreigners is reportedly becoming more routine.
'It has long been known that China has used the system on foreigners in the past — myself included. However, the sheer number of cases only now coming to light suggests that past foreign victims were either just a small fraction of the real number, or, more likely, that Chinese police and the MSS alike are becoming more carefree about placing foreign citizens into the system, especially when the victim is intended as a tool of foreign policy. Or, to put it plainly: hostage diplomacy,' Dahlin stated.
This comes amid broader international concern about Beijing's extraterritorial enforcement practices, including so-called 'overseas police stations' documented in multiple countries and transnational repression targeting diaspora communities.
Geopolitical Implications
The pattern carries significant implications for diplomatic relations. If foreign nationals can be detained as leverage in bilateral disputes — as the Czech case allegedly illustrates — it complicates normal state-to-state engagement and raises the risk calculus for businesspeople, journalists, and activists operating in or travelling to China. Several Western governments have in recent years issued updated travel advisories warning citizens of the risk of arbitrary detention in China, including exit bans that can trap individuals indefinitely.
The report from Safeguard Defenders is expected to increase pressure on governments to coordinate a multilateral response to what advocates describe as a systemic and escalating challenge to international norms governing the treatment of foreign nationals.
Point of View
Which is a qualitatively different accusation. Western governments face a genuine policy dilemma: strong individual bilateral responses risk retaliatory detentions, while multilateral coordination has so far proved slow. The Czech case, if accurately described, is especially pointed — it suggests China is willing to detain a foreign national not over a bilateral grievance but as a direct counter-move in an espionage dispute, a threshold that, if normalised, would fundamentally alter the diplomatic risk environment for all countries with significant people-to-people ties to China.

Frequently Asked Questions
What is 'hostage diplomacy' as described in the Safeguard Defenders report?
'Hostage diplomacy' refers to the alleged practice of Chinese authorities detaining foreign nationals to use them as leverage in pressuring other governments into making diplomatic concessions. The Safeguard Defenders report, authored by Peter Dahlin, documents multiple cases across different nationalities and argues the trend is growing.
What is Residential Surveillance at a Designated Location (RSDL)?
RSDL is a Chinese legal mechanism under which a person can be held at an undisclosed location, typically without access to a lawyer of their choosing or contact with their family. Critics and human rights groups describe it as a form of enforced disappearance that circumvents normal criminal procedure.
Which nationalities are among the documented cases?
The report names a Czech citizen, two US citizens, a British citizen, two Japanese businessmen working in rare earth materials, and a Chinese journalist whose whereabouts remain unknown. Chinese lawyers, journalists, and NGO workers are also cited.
Who is Peter Dahlin and why is he significant?
Peter Dahlin is the founder of the NGO Safeguard Defenders and a former victim of RSDL detention in China. His direct experience with the system gives him first-hand credibility in documenting how it operates against foreign nationals.
What is the broader significance of the report's findings?
The report suggests the publicly known cases of foreign nationals detained under RSDL are only a fraction of the real total, implying a systematic and expanding use of foreign citizens as foreign policy tools. This has prompted calls for a coordinated multilateral response from governments whose citizens are at risk.
