"For decades, billions of dollars of goods have crossed the Thai-Myanmar border through dozens of illegal trade gates in Kayin State’s Myawaddy Township that are run by armed groups. Each day, hundreds of trucks drive to the Thai side of the Thaung Yin (or Moei) River in Mae Sot, where their cargo is processed by Thai Customs, unloaded by hand onto small boats, ferried across the narrow stretch of water to Myawaddy and stored in warehouses for distribution throughout Myanmar. Most of this happens in broad daylight, and is legal on the Thai side and tacitly approved in Myanmar.

Stocks of imported goods have run out, while exports to Thailand have also been hit hard..."
