OFAC has designated the Zhao Wei Transnational Criminal Organisation pursuant to Executive Order 13581. Based in the Golden Triangle Special Economic Zone of Laos, the organisation is alleged to have exploited that region by “engaging in drug trafficking, human trafficking, money laundering, bribery, and wildlife trafficking”.
In conjunction, OFAC has also designated a network of 4 individuals and 3 entities across 3 jurisdictions (Laos, Thailand and China), for “materially assisting, sponsoring, or providing financial, material, or technological support for, or goods or services to or in support of, the Zhao Wei TCO, or for being owned or controlled by persons designated as part of this action”. Furthermore, the Kings Romans Casino (Laos) is alleged to be the main facilitator of the illicit activity in question. Links here for OFAC Notice and US Treasury press release.
