The AFC Cup is an annual international association soccer competition between domestic clubs sides run by the Asian Football Confederation (AFC). Qualification to the competition is to clubs from AFC-affiliated countries which fall into the AFC's 'developing nations' category as laid out in their 'Vision Asia' document. Countries which are 'mature' nations are entered into the AFC Champions League, and countries which are 'emerging' nations are entered into the AFC President's Cup. The 'developing nations' are the fourteen 'next-best' countries which lie outside the top-14 countries in the AFC region which send their club sides to the more prestigious AFC Champions League.
