The Economic Cooperation Organization or ECO is an Eurasian 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.

The Organization of Turkic States (OTS), formerly called the Turkic Council or the Cooperation Council of Turkic Speaking States, is an intergovernmental organization comprising all but one of the internationally recognized Turkic sovereign states: Azerbaijan, Kazakhstan, Kyrgyzstan, Turkey, and Uzbekistan; while Hungary and Turkmenistan are observers. Its overarching aim is promoting comprehensive cooperation among the Turkic peoples. First proposed by Kazakh president Nursultan Nazarbayev in 2006, it was founded on 3 October 2009 in Azerbaijan's Nakhchivan. The General Secretariat is located in Turkey's Istanbul.
