Since independence the countries of Central Asia embarked upon liberal reforms in their economic policies, including trade. However, persistence of formal and informal barriers to trade in general, and to services in particular, impedes further liberalization and development of the service industries in both countries. Moreover, existence of these barriers prevents large trade volumes between the neighbouring states. Therefore, it is very important to identify and analyze those barriers within each county. In the research formal and informal barriers to trade in services in Kazakhstan and Uzbekistan are first revealed and then assessed. Having identified the barriers it would be possible to provide policy recommendations for various international organizations and governments of the region with regard to further promotion of trade in services in Central Asia.
