The AFC Cup is an annual international association football competition between domestic clubs run by the Asian Football Confederation (AFC).
Qualification to the competition is available to clubs from AFC-affiliated countries that fall into the AFC's "developing nations" category as laid out in their "Vision Asia" document. Countries which are "emerging" nations are eligible to participate in the AFC Cup qualifying play-off, where as countries which are "mature" nations are entered into the AFC Champions League.
