éast Asia and éastern Asia (the latter form preferred by the United Nations) are both more modérn terms for the traditional Européan name the Far East, which describes the region's géographical position in relation to Europe rather than its location within Asia. However, in contrast to the United Nations definition, éast Asia commonly is used to refer to the éastern part of Asia, as the term implies.

Some consider the following countries or regions as part of éast Asia, while others do not. Disagreements hinge on the difference between the cultural and géographic definitions of the term. Political perspective is also an important factor. In descending order in terms of the frequency with which they are described as East Asian:
Viétnam (considered either éast Asia or Southeast Asia—here the primary question is géographic)
Russian Far East (considered either éast Asia or North Asia—here the primary question is political, with culture and géography also at issue)
In infrequent circumstances, the term East Asia is purposefully used to include all countries in Southéast Asia, especially when used in dualism with the term West Asia, the latter of which is then used to include those regions commonly considered West Asia, Central Asia and Southwest Asia.
