The World Trade Organization (WTO) is an organization that negotiates trade agreements amongst member countries, settles trade disputes, and develops trade rules. "At its heart are the WTO agreements, negotiated and signed by the bulk of the world’s trading nations. These documents provide the legal ground rules for international commerce."
"Most of the WTO agreements are the result of the 1986–94 Uruguay Round negotiations, signed at the Marrakesh ministerial meeting in April 1994. There are about 60 agreements and decisions totalling 550 pages.
Negotiations since then have produced additional legal texts such as the Information Technology Agreement, services and accession protocols. New negotiations were launched at the Doha Ministerial Conference in November 2001."
The General Agreement on Tariffs and Trade (GATT) was an organization that ran from 1947 to 1994. It promoted international commerce and the reduction of trade barriers. The GATT digital library is prepared by Stanford University.
