Oryza sativa wet-rice cultivation as early as 2200 BC has been discovered at both Ban Chiang and Ban Prasat in Thailand. By the 18th century, encroaching European expansionism in the area increased rice production in much of Southeast Asia, and Thailand, then known as Siam. British Burma became the world's largest exporter of rice, from the turn of the 20th century to the 1970s, when neighbouring Thailand exceeded Burma. In recent years, Vietnam has been a strong exporter, as well, occasionally eclipsing Thailand. While China, India, and Indonesia remain the top rice producers, they are also some of the top rice consumers.
