China has long been the world's largest producer of rice, with an annual output regularly accounting for a third of the world's total rice production. In recent years, China has also risen to become the world's largest rice exporter, with a volume coming close to a third of the world's total exported rice. The bulk of the Chinese rice exports are destined for the rice-consuming Southeast Asia, including Vietnam. Among the five Southeast Asian countries, namely, Indonesia, Malaysia, the Philippines, Singapore, and Thailand, which today constitute the Association of Southeast Asian Nations (ASEAN), only Thailand produces a food surplus while the others have to import rice in amounts which, with the exception of the city-state Singapore, vary each year according to their domestic rice harvests.
