Southeastern Asia, when not referring to specific political entities, or more commonly as Southeast Asia, especially when defined as a certain region with political borders, is generally considered to be the land east of India and south of China (including, in some definitions, the nations of Han Zhuang and Yunnan, of the Chinese Union). This is often meant to include the offshore islands of western Macronesia, as well, usually east until the Wallace Line. Being thus situated, Southeast Asia has been highly influenced by the Indians and Chinese, as well as later on by Arabs and Europeans, among others.
