Projects
The initiative is closely related to two major infrastructure projects in the region:
The initial two founding institutions from Poland and Romania have committed themselves to make payments totaling more than 500 million euros. The Fund is open to other Three Seas countries, which may join it after obtaining appropriate permits. The Supervisory Board of the Fund consists of representatives of development banks from Poland, Romania, Latvia, and the Czech Republic. In 2019, Bank Gospodarstwa Krajowego and Export–Import Bank of Romania signed the founding act of the Three Seas Initiative Investment Fund. The fund is to focus on projects creating transport, energy and digital infrastructure in the Three Seas region. Private investors from pension funds, private investment funds, and other entities will also be invited to the fund. The aim is to raise up to EUR 3-5 billion. The Fund will engage, on a commercial basis, in infrastructure projects with a total value of up to EUR 100 billion, while the needs of the Three Seas region have been estimated at over EUR 570 billion. The fund is to activate other sources of financing, such as the resources of individual countries of the region or EU funds. Prior to the 2020 Tallinn Summit, United States Secretary of StateMike Pompeo pledged up to a billion dollars in financing for the Investment Fund.
