The Eurasian Economic Community (EurAsEC or EAEC or EEC) was put into motion on 10 October 2000 when Belarus, Kazakhstan, Kyrgyzstan, Russia and Tajikistan signed the treaty. EurAsEC was formally created when the treaty was finally ratified by all five member states in May 2001.
EurAsEC grew out of the CIS Customs Union. All the members of EurAsEC are also members of the older Commonwealth of Independent States and the relationship between the two organisations is ambiguous. The members have also all agreed that EurAsEC should be merged with the Central Asian Cooperation Organization (CACO).
With the revival of EurAsEC in 2005 there is a possibility for the Common Economic Space agenda to be implemented in its framework with or without the participation of Ukraine. This was confirmed in August 2006
and in October 2007 it was announced that a customs union would be formed by Russia, Belarus, and Kazakhstan by 2011 with other members being able to join later.
In May 2002, Moldova and Ukraine were granted observer status within EurAsEC; however, Ukraine subsequently revealed its desire not to become a full member state. Armenia received observer status in April 2003.
Uzbekistan applied for membership in October 2005
when the process of merging the Central Asian Cooperation Organization and the Eurasian Economic Community began. The organizations joined on 25 January 2006. It is not clear what will happen to the status of current CACO observers that are not observers to EurAsEC (Georgia and Turkey).
