Golden Triangle — Uncover the Opium Shadow

🎭Your Mission

You are an investigative journalist, hot on the trail of a global conspiracy in Chiang Rai, Thailand, in 1980.

The misty confluence of the Mekong and Ruak rivers, the Golden Triangle

Chiang Rai: The Golden Triangle, between legends and dark Cold War truths.

« Opium was simply a convenient cash crop for the CIA's covert operations. »
Alfred W. McCoy, 'The Politics of Heroin: CIA Complicity in the Global Drug Trade'

The Secret Opium War

The Golden Triangle, a border area between Thailand, Laos, and Myanmar, was for decades one of the world's largest opium producers. From the 1950s, as the Cold War intensified in Southeast Asia, Western intelligence agencies, particularly the CIA, saw an opportunity. By supporting anti-communist groups, such as the remnants of the Chinese Kuomintang exiled in Burma, the CIA turned a blind eye to their opium trafficking, even using it to fund clandestine operations, creating a complex web of power, drugs, and intrigue.

At the heart of this complex network was the Nugan Hand Bank, an Australian merchant bank founded in 1973. It quickly became a hub for money laundering from drug trafficking and covert operations. Its connections to former high-ranking US military and intelligence officials fueled rumors of direct involvement in covert CIA funding. The mysterious death of one of its founders and its spectacular collapse in 1980 brought to light a web of conspiracies that stretched from Washington to the poppy fields of the Golden Triangle.
