The Asian Infrastructure Investment Bank (AIIB) announced Thursday that its Board of Governors has adopted resolutions approving 13 applicants to join the bank, bringing the bank's total approved membership to 70.

A spokesperson of AIIB made the announcement at a press conference here. This is the first time the multilateral development bank has welcomed new prospective members since its inception.

The approved applicants are five regional prospective members -- Afghanistan, Armenia, Fiji, China's Hong Kong and Timor Leste -- and eight non-regional prospective members, namely Belgium, Canada, Ethiopia, Hungary, Ireland, Peru, Sudan and Venezuela.

"The interest in joining AIIB from around the world affirms the rapid progress we have made to establish the bank as an international institution," said Jin Liqun, president of AIIB.

"I am very proud that AIIB now has members from almost every continent, and we anticipate further applications being considered by our Board of Governors later this year," he said.

The 13 prospective members will officially join AIIB once they complete the required domestic processes and deposit the first installment of capital with the bank.

The shares allocated to the new prospective members come from the bank's existing pool of unallocated shares, according to AIIB.

With 57 signatories at its establishment in 2015, AIIB aims to provide financing to address the daunting infrastructure needs across Asia.
