With authorized capital of 100 billion U.S. dollars, AIIB will invest in infrastructure, energy, transportation, urban construction, water supply and logistics as well as education and health care.
Specific loan policies will be discussed by the board meeting and released after approval.
In terms of the energy sector, Jin said the bank will take account of Asia's rising energy demands and the battle against climate change when deciding if it will finance coal-fired and nuclear power projects.
"Our target projects must be financially, environmentally and socially sustainable," Jin said.
AIIB will hand out loans from mid 2016, according to Jin, adding that the bank will keep in close contact with other multilateral and bilateral development organizations.
The bank is open to global professionals and to more members based on voting of the board, according to Jin.
Based on the GDP volume and capital contribution, China holds the highest voting stake among all members. As new members join, all founding members' shares and voting stakes will be "gradually diluted."
LEAN, CLEAN, GREEN
The AIIB has a clear three-tier structure -- a board of governors, a board of directors and a management team, which will carry out their duties accordingly.
The bank will enroll employees openly and transparently to select those with good work ethics, outstanding professional expertise and strong commitment, according to Jin.
Everyone is welcome to apply for the available positions, however, the recruitment process will be strict, said Jin.
"There will be no lifelong positions here. All employees will have one-year probation period," Jin said.
Profit maximization will not be AIIB's goal due to its multilateral financial institution status, but the bank's investment projects have to be profitable to ensure financial sustainability, according to Jin.
To reduce operational costs, the board will not be based in the bank and free competition will be encouraged in recruitment and purchase. Meanwhile, the audit department will oversee business compliance, performance and work ethics.
The bank is also working on documents to accord the business practices with environmental and social development.
"There will be zero tolerance of corruption, and we will make the bank lean, clean and green," Jin said.
