Asia-Pacific Economic Cooperation (APEC) is a forum for 21 Pacific Rim countries (formally Member Economies) that seeks to promote free trade and economic cooperation throughout the Asia-Pacific region. Established in 1989 in response to the growing interdependence of Asia-Pacific economies and the advent of regional economic blocs (such as the European Union) in other parts of the world, APEC works to raise living standards and education levels through sustainable economic growth and to foster a sense of community and an appreciation of shared interests among Asia-Pacific countries. Members account for approximately 40% of the world's population, approximately 54% of the world's gross domestic product and about 44% of world trade.

An annual APEC Economic Leaders' Meeting is attended by the heads of government of all APEC members except Taiwan (represented under the name Chinese Taipei) by a ministerial-level official. The location of the meeting rotates annually among the member economies, and until 2011, a famous tradition involved the attending leaders dressing in a national costume of the host member.
