Over the years of independence, Kazakhstan has initiated and participated in the creation of a number of international organizations, but none of them, perhaps, has caused such contradictory assessments as the Eurasian Economic Union (EEU). The idea was originally proposed by Nursultan Nazarbayev in May 1994. Two years later, an Agreement was signed between Kazakhstan, Belarus, Kyrgyzstan and Russia on deepening integration in the economic and humanitarian fields (Tajikistan then later joined the alliance of the four). An Integration Committee was created, headed by the First Deputy Prime Minister of Kazakhstan Nigmatzhan Isingarin.
