SINGAPORE (Reuters) - China will likely take a 25-30 per cent stake in the Asian Infrastructure Investment Bank (AIIB) and India is likely to be the second-largest shareholder, delegates attending a meeting of the bank's founding members in Singapore said on Friday.

China's share in the US$100 billion lender will be less than 30 per cent, an Asian delegate attending the meeting told Reuters.

A second delegate said India's share will be between 10 to 15 per cent. Both spoke on condition of anonymity.

In all, Asian countries will own between 72-75 per cent of the bank, while European and other nations will own the rest.

The three-day meeting of the China-backed AIIB is aimed at finalising the draft of articles of agreement that would decide the share of member countries and the bank's initial capital.

A third delegate said the talks have ended and now each country representative would take the proposals back to their governments for a final decision.

There was no immediate comment from the AIIB or Chinese officials on the discussions in Singapore.

A total of 57 countries have joined AIIB as its prospective founding members, throwing together countries as diverse as Iran, Israel, Britain and Laos.

The United States and Japan have stayed out of the China-led institution, seen as a rival to the U.S.-dominated World Bank and Japan-led Asian Development Bank, citing concerns about transparency and governance - although Tokyo for one is keeping its options open.

AIIB's expected launch next year is coming at a time when the space for infrastructure lending is already crowded due to the presence of major multilateral lenders and Japan's latest move to provide $110 billion for Asian infrastructure projects.

The amount of Japanese funds, to be invested over 5 years, tops the expected US$100 billion capitalisation of the AIIB.
