Convention on the Organisation for Economic Co operation and Development

The Convention on the Organisation for Economic Co-operation and Development is the 1960 treaty that transitioned the Organisation for European Economic Co-operation into the Organisation for Economic Co-operation and Development. The treaty states that OECD decisions are binding on members that vote for those decisions once those decisions are approved in accordance with those members' constitutional processes.

When a state is invited to join the OECD, it must ratify the convention to join. As of 2013, 34 states have ratified the convention and thereby joined the OECD.
