Abstract. Foreign experience (EU and NAFTA) in single services market formation is analyzed in the article, key elements which are practically important for national business and state structures in the CIS development context are revealed. An important feature of modern regionalism is the liberalization of service industry. This idea is not new for CIS countries as well  it was declared in its constituent documents. However, up to date there are no real results in this field. More close economic ties develop in the Eurasian Economic Community (EurAsEC) framework. The creation of the Customs Union of Russia, Kazakhstan and Belarus in 2010 became an important landmark on the way to economic integration between them. In 2009–2011, the three countries consistently declared their ambition to create the Common Free Market Zone (CFMZ) in 2012, implicating the freedom of commodities, services, labor and capital movement. The freedom of commodities movement is already achieved within the Customs Union, with few exceptions. The liberalization of service markets will be one of the key elements of integration extension and transit to the common market. Moreover, the integration in this sphere will allow for a greater diversification of national economies, interstate trade structure, and will also lead to creation of new work positions.
