The Golden Triangle is the area where the borders of Thailand, Laos, and Myanmar meet at the confluence of the Ruak and Mekong rivers. The name "Golden Triangle"coined by the CIA is commonly used more broadly to refer to an area of approximately 950,000 square kilometres (367,000 sq mi) that overlaps the mountains of the three adjacent countries. Along with Afghanistan in the Golden Crescent, it has been one of the most extensive opium-producing areas of Asia, and of the world, since the 1950s. Most of the world's heroin came from the Golden Triangle until the early 21st century when Afghanistan became the world's largest producer.
