In October 2025, the United States and United Kingdom launched what officials described as the largest coordinated action ever taken against transnational cybercrime networks in Southeast Asia. At the center of this $15 billion investigation sits Chen Zhi, the 37-year-old Chinese-born founder of Cambodia's Prince Group—and the story of why China didn't crack down harder on his operations reveals uncomfortable truths about geopolitics, diplomatic priorities, and the evolving US-China relationship.
The Empire Built on Suffering
Chen Zhi's rise reads like a dark fairy tale. Born in Fujian province in 1987, he started with modest ventures—an internet café and gaming centers in Fuzhou. By 2011, he had moved to Cambodia, sensing opportunity in the country's booming real estate market fueled by Chinese investment. Within a decade, he had transformed himself into one of Cambodia's wealthiest and most politically connected figures, advising Prime Minister Hun Manet and his father, former Prime Minister Hun Sen.
The Prince Group conglomerate appeared legitimate on the surface, with interests spanning real estate, banking, airlines, and shopping malls. Prince Plaza in Phnom Penh became a landmark. Prince Bank served thousands of customers. Chen received Cambodia's highest royal title, Neak Oknha, requiring a donation of at least $500,000 to the government.
But beneath this veneer of respectability, US and UK authorities allege, Chen operated one of Asia's largest criminal enterprises. The indictment unsealed in October 2025 paints a chilling picture: at least ten forced-labor compounds across Cambodia where thousands of trafficked workers—many lured by false job advertisements—were held behind barbed wire and subjected to torture if they failed to meet daily fraud quotas. These "scam compounds" allegedly generated over $30 million per day at their peak through cryptocurrency fraud schemes targeting victims worldwide.
China Knew—But Chose Limited Action
Here's where the story becomes geopolitically fascinating: China knew about Prince Group's activities for years but took only measured, selective action.
Chinese authorities began investigating Prince Group in May 2020, when the Beijing Municipal Public Security Bureau established a special task force specifically targeting what they called a "notorious transnational online gambling criminal group." Court documents from multiple Chinese provinces between 2020 and 2022 describe Prince Group operations generating at least 5 billion yuan (approximately $700 million) in illegal profits from online gambling targeting Chinese citizens.
China prosecuted low-level operatives—betting agents, money mules, and minor figures in the Prince Group network. Provincial courts in Guangdong, Sichuan, Henan, and Anhui convicted dozens of individuals connected to the schemes. But Chen Zhi himself was never charged in China. The Prince Group as a corporate entity was never directly targeted by Chinese prosecutors.
Why the restraint?
The Cambodia Connection: Too Politically Sensitive to Touch
The answer lies in Cambodia's strategic importance to China and the deep entanglement between Prince Group and Cambodia's ruling elite.
Cambodia has become one of China's most reliable allies in Southeast Asia—perhaps Beijing's closest friend in the region. Decades of diplomatic effort and billions in investment have cemented this relationship. Cambodia consistently supports China's positions in ASEAN, opposes Western criticism of China's human rights record, and provides a friendly environment for Chinese economic expansion through Belt and Road Initiative projects.
Chen Zhi positioned himself as not just a beneficiary of this relationship but as a key facilitator of it. One of his investment firms was literally named "Belt Road Capital Management," explicitly invoking Beijing's signature foreign policy initiative. US indictment documents reveal that Chen and his associates maintained direct coordination with officials from China's Ministry of Public Security and Ministry of State Security, allegedly bribing them for advance warning of law enforcement raids.
More critically, Chen became deeply embedded in Cambodia's power structure. He served as an adviser to Interior Minister Sar Kheng—Cambodia's top law enforcement official—and co-invested with the minister's son in the Jin Bei Group casino. He advised both Hun Sen and his successor Hun Manet. Any aggressive Chinese prosecution of Chen would necessarily implicate Cambodia's most powerful figures, potentially embarrassing the Hun family and straining the China-Cambodia relationship that Beijing had invested so heavily in cultivating.
The Strategic Calculation: Chinese Victims vs. Regional Stability
China's approach to Prince Group illustrates a calculated strategic choice. Beijing focused its crackdown on operations that directly harmed Chinese citizens—prosecuting the gambling operations that drained money from mainland consumers and the scam compounds that initially targeted Chinese victims. This allowed China to demonstrate responsiveness to domestic concerns about capital flight and fraud while avoiding the diplomatic fallout of directly confronting Chen or destabilizing Cambodia's government.
The US Treasury Department's analysis reveals an unintended consequence of this selective enforcement: as China tightened controls and increased surveillance of operations targeting Chinese citizens, criminal networks like Prince Group simply pivoted to targeting Americans and Europeans instead. Chinese losses to online scams decreased by 30 percent in 2024, while American losses increased by 40 percent in the same period—a nearly $10 billion hit to US citizens in 2024 alone.
From Beijing's perspective, once Prince Group's operations were no longer primarily victimizing Chinese nationals, the urgency of further action diminished. The diplomatic cost of disrupting the Cambodia relationship outweighed the benefit of stopping fraud primarily affecting Western victims.
What This Reveals About US-China Relations
The Prince Group case illuminates several uncomfortable realities about the current state of US-China relations:
Diverging Enforcement Priorities: The US and China are nominally cooperating against transnational crime, but their enforcement priorities increasingly diverge based on whose citizens are being harmed. China's selective crackdown that pushed scammers toward American targets suggests limited concern for cross-border crime that doesn't affect Chinese interests directly.
The Limits of Strategic Competition: While US-China competition intensifies in technology, trade, and military spheres, cooperation on law enforcement remains superficial. China was willing to investigate Prince Group when Chinese citizens were victims, but didn't share intelligence with US authorities or take comprehensive action once the schemes shifted to targeting Americans.
Proxy Battlegrounds: Cambodia has become a testing ground for US-China influence. The fact that Chen could operate openly with protection from Cambodian officials—who themselves maintain close ties to Beijing—while running operations that ultimately harmed US citizens demonstrates how regional allies can become enablers of activities contrary to great power interests.
The Corruption Nexus: The case highlights how corruption in third countries creates safe havens for transnational crime that exploits gaps in great power cooperation. Chen allegedly bribed officials in multiple countries, including attempts to bribe Chinese law enforcement, creating a protection network that transcended any single government's control.
Different Conceptions of Sovereignty: China's reluctance to fully crack down on Prince Group reflects a broader pattern of prioritizing relationships with friendly authoritarian governments over addressing transnational crime. The US and UK's aggressive sanctions and asset seizures represent a different approach—one that's willing to strain diplomatic relationships to combat criminal networks.
The Diplomatic Calculations Moving Forward
The massive US-UK action against Prince Group—seizing $15 billion in cryptocurrency, sanctioning 146 entities and individuals, freezing properties across multiple jurisdictions—represents a new escalation in combating Southeast Asian cybercrime. But it also creates diplomatic complications.
Cambodia's government has responded cautiously, with Interior Ministry spokesman Touch Sokhak stating: "We are not protecting individuals that violate the law, but it does not mean that we are accusing Prince Group or Chen Zhi of committing crimes like the allegations made by the US or the UK." This careful language reflects Cambodia's difficult position: balancing its close relationship with China, its desire for Western investment, and the need to avoid appearing complicit in massive fraud.
For China, the US action creates a dilemma. Beijing can't appear to be protecting someone accused of defrauding billions from Western citizens, yet aggressive cooperation with US authorities on this case would mean compromising its relationship with Cambodia and potentially exposing its own officials' involvement in the corruption network that protected Prince Group.
Conclusion: What It Means for US-China Relations
The Prince Group scandal reveals that despite increasing tensions and competition, US-China relations aren't approaching a complete breakdown—they're becoming increasingly transactional and compartmentalized. China cooperates when its interests align (protecting Chinese citizens from fraud) but shows little inclination to act when Western interests are at stake, particularly if doing so would compromise important regional relationships.
For the United States, the case demonstrates the limitations of expecting Chinese cooperation on transnational crime and the need for building independent enforcement capabilities and regional partnerships. The unprecedented scope of the US-UK action—the largest cryptocurrency seizure in history—shows Western authorities developing the tools and coordination to act without Chinese cooperation.
The selective nature of China's enforcement against Prince Group isn't just about one criminal network. It's a window into how great power competition plays out in the gray zones of transnational crime, where diplomatic relationships, economic interests, and law enforcement objectives collide. As US-China relations continue to evolve, we can expect more such cases where coordination proves elusive and competing interests trump shared goals of fighting crime.
Chen Zhi remains at large, presumably in Cambodia where he faces no extradition risk. The $15 billion in seized Bitcoin represents justice for some victims, but the broader network of scam compounds continues to operate across Southeast Asia. Until China, the US, and regional governments find ways to truly cooperate beyond rhetoric—overcoming the diplomatic sensitivities and competing interests that allowed Prince Group to flourish—these operations will likely continue, finding new victims and adapting to enforcement pressure.
The question isn't whether China will eventually crack down comprehensively on networks like Prince Group. The question is whether US-China relations can evolve to a point where both nations prioritize fighting transnational crime over protecting strategic relationships, even when it's diplomatically uncomfortable. The Prince Group case suggests we're not there yet—and may not be for some time.
