The roots of the opium production problem in Southeast Asia go back to the 19th century. The region is home to the “Golden Triangle”, an area long associated with opium and heroin production, located where the borders of Myanmar, Lao People’s Democratic Republic (Lao PDR) and Thailand converge along the Mekong River. Twenty years ago, the Golden Triangle was the largest heroin‐producing area in the world, supplying the region’s own demand as well as exporting its surplus to North‐east Asia, Europe and the United States of America. In the 1990s and early 2000s, national and regional efforts succeeded in reducing both opium production and trade in the region, though they subsequently increased.
