In the twentieth century, the Central Asian countries of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan passed through a complex historical period. They were originally founded as republics of the Soviet Union in the 1920s-30s as a result of national and territorial state delimitation. The process of the creation of new national state formations began after the Soviet Union disintegrated and these republics achieved independence. At the same time, the region's nations are facing complex problems of transition and the creation of new societies. Nevertheless, these countries have to continue the process of political and economic reforms, as well as development of civic institutions. The Central Asian nations established contacts with foreign states and international organizations and started to form a system of interstate relations between the countries of the region. There are potentials for development of regional integration of Central Asia. Future integration will depend on the readiness of the nations to carry out political and economic reforms, introduce forms and methods of economic regulation compatible with global norms, and most important, international support of political reforms and regional integration.
