Australia is “well and truly” disposed to join the China-led Asian Infrastructure Investment Bank (AIIB), Prime Minister Tony Abbott said on Wednesday, but wants to know how much power Beijing would hold in the institution before a formal decision. Fairfax Media citing government sources, reported the federal cabinet has approved Australia signing a “memorandum of understanding” on joining the AIIB. Australia, South Korea and Japan are the notable regional absentees from the bank, which the United States had warned against.
