The International Investment Bank (IIB) is a multilateral development bank established in 1970, originally by the Council for Mutual Economic Assistance (Comecon) countries. Its founding and participating members have been mostly from Eastern Europe and Asia.
As of recent years, India has never been a member of the IIB. Member states have included countries such as:
Russia
Vietnam
Czech Republic (though it exited in 2021)
Hungary, Bulgaria, Romania, Slovakia, Mongolia, etc.
IIB was formed to promote economic cooperation among socialist and post-socialist countries.
Russia was the largest stakeholder, hosting its headquarters in Moscow until 2023.
After the Russia-Ukraine conflict, several countries withdrew membership (like Czech Republic, Bulgaria, Romania).
IIB recently relocated its headquarters to Budapest, Hungary, but Hungary also announced its exit in 2023.
India has no association with IIB as a member or observer.
