Web search results confirm that TRAFFIC monitors wildlife trade and that there are reports linking organized crime in South Africa to Vietnamese syndicates involved in wildlife trafficking. One source specifically mentions 'Vietnamese-led wildlife trafficking in Africa' and another references 'Rhino horn sourcing by organized crime syndicates in South Africa.'

One web search result explicitly states, 'As of early 2026, investigations show that these networks have shifted from small-scale trafficking to smuggling large volumes of wildlife products, including rhino horns and lion bones.' Another web search notes that Vietnam remains a hub for smuggling products like ivory, pangolin scales, and rhino horns from Africa, supporting the theme of large-scale smuggling.

Web search results confirm that South African authorities arrested Vietnamese nationals in connection with wildlife trafficking, noting that these networks are part of wider transnational criminal activities involving corruption. One source mentions the arrest of Chu Dang Khoa, and another references the arrests of Vietnamese nationals in the context of rhino horn trafficking.

Multiple web search results describe Chu Dang Khoa, also known as Michael Chu, as a high-profile figure, a 'Diamond King,' and being accused of involvement in the illegal wildlife trade, fitting the description of a financier and organizer.

Web search results confirm arrests of Vietnamese nationals (including Chu Dang Khoa) in connection with rhino horn trafficking. One source mentions 'South African authorities have arrested two Vietnamese nationals, Huy Bao Tran and Chu Dang Khoa, in connection with a large-scale rhino horn smuggling network.' Another source discusses rhino horn trafficking arrests generally.

Two independent web search results detail the seizure of 20 rhino horns (weighing 35.7 kg) and approximately 150 kg of other animal parts at Singapore's Changi Airport. The timing relative to a false report is also mentioned in the context of the seizures.
