The geographical terms "Northern Buddhism" and "Southern Buddhism" are used to refer to the Buddhist traditions transmitted outside of India. "Northern Buddhism" refers primarily to Buddhism practiced in China, Korea, Japan, Tibet and Mongolia, where the Mahayana tradition is followed."Southern Buddhism" is practiced in Sri Lanka, Burma,Thailand, Cambodia, and Laos, and follows the Theravada tradition. Chinese Buddhism, being one of the two main branches of "Northern Buddhism," is a result of the encounter between Buddhism in Central Asia and the Chinese civilization during the first century C.E. This highly evolved form of Buddhist practice was later transmitted to Japan and Korea,where it is known to Western academics as "East Asian Buddhism."
