Kazakh President Nursultan Nazarbaev has signed a law approving Kyrgyzstan's joining Russia-led Eurasian Economic Union (EEU), finalizing the process of Bishkek's membership in the group.
Kazakhstan was the last country to ratify the agreement on Kyrgyzstan's accession to the EEU after it was approved by the parliaments of Armenia, Belarus, and Russia.
Kyrgyz Deputy Prime Minister Valery Dil said last week that the customs offices on its borders will be opened in days after Kazakhstan fully ratifies all the corresponding documents.
The agreement on Kyrgyzstan's accession to the EEU was signed in December at a session of the Supreme Eurasian Economic Council in Moscow.
Protocols to the agreement were signed by the EEU member states in May.
Kyrgyzstan will become the fifth member of the grouping.
Russia, Belarus, and Kazakhstan signed a treaty on the EEU in Astana on May 29, 2014, which came into force on January 1, 2015.
Armenia joined the group in December.
