The Organisation for Economic Co-operation and Development was founded in 1961.
The OECD was created on 30 September 1961, succeeding the Organisation for European Economic Co-operation. The OEEC had coordinated postwar European recovery, including administration connected with the Marshall Plan.
The OECD expanded that cooperation into a broader forum for governments to compare policies and develop evidence-based standards. Its work covers taxation, education, economic growth, trade, employment, environment and many other policy areas.
The OECD is not a trade regulator like the WTO. It does not administer a single set of global trade agreements. Instead, it produces statistics, peer reviews and policy recommendations, making it a frequent source of comparative economic information used alongside WTO trade data.
