Golden Triangle

The Golden Triangle

(Burmese: ရွှေတြိဂံ နယ်မြေ, IPA: [ʃwè tɹḭɡàɴ nɛ̀mjè]; Thai: สามเหลี่ยมทองคำ, IPA: [sǎːm.lìəm.tʰɔːŋ.kʰam]; Lao: ສາມຫຼ່ຽມທອງຄຳ; Vietnamese: Tam giác Vàng) is one of Asia’s two main opium-producing areas.

It is an area of around 950,000 square kilometres (367,000 sq mi) that overlaps the mountains of three countries of Southeast Asia: Myanmar, Laos and Thailand. 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.
