شمال شرق آسيا
Observers preferring a broader definition of "East Asia" often use the term Northeast Asia to refer to China, the Korean Peninsula, and Japan, with Southeast Asia covering the ten ASEAN countries. This usage, which is seen in economic and diplomatic discussions, is at odds with the historical meanings of both "East Asia" and "Northeast Asia". The Council on Foreign Relations of the United States defines Northeast Asia as Japan and Korea.
