There are about 30 such agreements. Based on these agreements, the member countries trade with each other. They sell items to each other and follow a set of rules. They have to give a special job to the other country. The phrase used (for such and many alike items) is to give the other country a special job – this is known as to give the other country "a most favored country job". From 2004, if a member sells any item to another member country, the same type of item should be offered to all other member countries.
