The Economic Cooperation Organization or ECO is an Asian political and economic intergovernmental organization that was founded in 1985 in Tehran by the leaders of Iran, Pakistan, and Turkey. It provides a platform to discuss ways to improve development and promote trade and investment opportunities. The ECO is an ad hoc organisation under the United Nations Charter. The objective is to establish a single market for goods and services, much like the European Union. After the dissolution of the Soviet Union, the ECO expanded to include Afghanistan, Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan in 1992.
