The statement noted that there is an estimated infrastructure financing gap of around 8 trillion U.S. dollars in the Asian region over the current decade. "The AIIB will be part of the solution to closing this gap," it said.
The two ministers said in the statement that joining the AIIB presents Australia with great opportunities to work with Australia's neighbors and with its largest trading partner, China, to drive economic growth and jobs.
They noted that the AIIB will work closely with the private sector, paving the way for Australian businesses to take advantage of the growth in infrastructure in the region.
As for the governance of the AIIB, the statement said it will be based on best practice, ensuring that all members will be directly involved in the direction and decision making of the bank in an open and transparent manner.
