The latest regional integration entity in post-Soviet should not be merely based on experience of CIS i.e. Commonwealth of Independent States, but also on two other successors named EurAsEc i.e. Eurasian Economic Community as well as Custom Union among Belarus, Kazakhstan and Russia, which have been formalized after 10 years. One of the interesting features associated with formation of Eurasian Union is that the idea was actually proposed by Nursultan Nazarbayev, who was recognized as president of Kazakhstan. At that time, leader of Kazakh had strongly defended 5 major Soviet states in to the permanent framework of Soviet Union. These states include Russia, Kyrgyzstan, Belarus, Tajikistan and Kazakhstan. In addition, future expansion of Eurasian Union would definitely encompass Armenia, Azerbaijan, Ukraine and various other territories.
