The "Bamboo network" or the "Chinese Commonwealth" is a term used to conceptualize connections between businesses operated by the Overseas Chinese community in Southeast Asia.
 It links the Overseas Chinese business community of Southeast Asia, namely Myanmar, Malaysia, Indonesia, Thailand, Vietnam, the Philippines, and Singapore with the economies of Greater China (Mainland China, Hong Kong, Macau, and Taiwan).

 Overseas Chinese have dominated much of the economy in Thailand, Malaysia, the Philippines, Cambodia and Indonesia since the 19th century and today exert a powerful economic influence throughout the region.
