Finance officials said on Sunday that China will follow international practice and allow other nations to inject capital into the Asian Infrastructure Investment Bank.

Jin Liqun, secretary-general of the Multilateral Interim Secretariat for Establishing the AIIB, said that even though China is the biggest shareholder in the financial institute, the country will have no privileges but more obligations to improve Asia's economy in a fair and sustainable manner.

Eager to enhance regional connectivity, investment and trade ability, China committed $50 billion in October and organized 27 partner countries to form the AIIB. The China-led bank will target infrastructure projects such as the construction of roads, ports and other infrastructure across Asia, with a focus on Association of Southeast Asian Nation members.
