Establishment of the Customs Union in 2010 accelerated the pace of integration in post-Soviet space. Integration of Russia with Kazakhstan, Belarus and other CIS countries is hindered by the fact that each country seeks only profit. SES-4 (Belarus, Kazakhstan, Russia, Ukraine) had the greatest potential since its inception in 2003. The idea of a Customs Union within EurAsEC that would create a common customs territory, eliminate customs checks at internal borders and unify the mechanisms for regulating the economy and trade was formulated in the Treaty on the Customs Union and Common Economic Space. The Republic of Belarus regards the Customs Union as the defining framework of the EurAsEC, and at the same time - as a transitional stage to a more in-depth form of integration - the Common Economic Space (CES-3).
