[IMAGE:flat-design-coffee-tourism-vietnam-indonesia-thailand-esim-connectivity-illustration]
Southeast Asia is one of the world’s great coffee-growing regions. Vietnam is the world’s second-largest coffee producer. Indonesia’s Sumatra, Java, Flores, and Sulawesi produce some of the world’s most distinctive Arabica varieties. Thailand’s northern highlands have developed a specialty coffee industry that rivals Central American origins. Here’s the connectivity picture for coffee tourism.
