The Chinese embassy in Phnom Penh on Sunday promised assistance to Cambodian police after a video surfaced in which a Chinese gangster declares he will seize control of a major Cambodian city while 20 other men, shirtless and tattooed, cheer him on.

“Kampong Som, in the next three years, whether it will be safe or chaotic is under my control,” the man declares, referring to Cambodia’s major port city, also called Sihanoukville.

The video appeared days after Cambodia’s Interior Ministry released a report saying that Chinese nationals were the most criminally active foreigners in Cambodia. That report said 241 Chinese nationals were detained in the first quarter of 2019, out of a total of 341 detentions.

“Cambodia's Chinese Embassy is paying great attention to this issue and is coordinating the thorough investigation conducted by Cambodian and Chinese police,” wrote the embassy in a Facebook post. “We believe the case will be solved soon.”

Cambodia and China have steered a course toward deeper economic and social ties in the past years. Sihanoukville has been a microcosm of that relationship.

The city has seen an influx of money from China--money that’s built tens of casinos and US$500,000 apartments in a city where many Cambodians squat in tin sheds and can’t make ends meet.

Cambodia’s immigration department estimates 78,000 Chinese nationals live in Sihanoukville alone--only a fraction of whom have work permits. 

Sihanoukville has long been a haven for gangsters of all nationalities. Its most famous denizens include the eccentric Russian real estate magnate Sergei Polonsky, who started a war with rival gangster Nikolai Doroshenko, a Soviet-trained herpetologist with vast business holdings in the the town.
