Nanyang is the Chinese name for the warmer and fertile geographical region south of China, otherwise known as the 'South Sea' or Southeast Asia. The term came into common usage in self-reference to the large ethnic Chinese migrant population in Southeast Asia, and is contrasted with Xiyang , which refers to the Western world, and Dongyang , which refers to Japan. The Chinese press regularly uses the term to refer to the region stretching from the Yunnan province to Singapore (in the south) and from India to Vietnam (in the west and east); in addition, the term also refers to Indonesia, Brunei and the Philippines in the region it encompasses.
