Since 2015, focus on developing relations between former members of the Soviet Union is on continued development of the Eurasian Economic Union (EAEU), itself a further development of the Eurasian Customs Union established in 2010. It is modeled on the integration of the European Union and comprises 5 member states: Belarus, Russia, Kazakhstan, Armenia and Kyrgyzstan. Tajikistan has also expressed an interest in joining. However, the EAEU is only an economic union, and at present, political integration remains within the remit of the Union State.
