The World Bank and the International Monetary Fund (IMF) are ready to cooperate with China and the Asian Infrastructure Investment Bank (AIIB), the World Bank Group president and the head of the IMF said on Thursday.

"Our expectation is that we will continue to have a very close relationship and that we will work with China to tackle their most complex and difficult issue," said Jim Yong Kim, World Bank Group president. He spoke at the World Bank/IMF Spring Meetings 2015 opening press conference.

"I first of all want to congratulate China for taking such a bold step in the direction of multilateralism," Kim said.

Kim stated that in recent years, the collaboration between China and the World Bank Group "has only gotten stronger". They have had close communication with Chinese officials since the beginning of the foundation of the AIIB.

"I suspect that in the early period we'll play a much larger role in project preparation because we have much more technical expertise than the AIIB has right now," Kim said. "But there's no reason why we would not do a lot of the project preparation, for example, through our global infrastructure facility, and then AIIB could be a co-investor."

Kim said last week that the World Bank welcomed the AIIB in advance of the spring meetings.

The World Bank Group is waiting for a point at which there are articles of agreement or a constitution for AIIB framing specific areas in which the AIIB will invest, to continue the conversation between both sides, Kim said.

The China-led AIIB's prospective founders' list increased to 57 countries as of Wednesday. The latest founding members are Sweden, Israel, South Africa, Azerbaijan, Iceland, Portugal and Poland, according to the Ministry of Finance.

The IMF also expressed that it is prepared to collaborate with AIIB.

"That (AIIB) is a most welcomed institution and one with which the IMF certainly is planning to cooperate with," said Christine Lagarde, the managing director of IMF.

"The proposal to have a completely dedicated institution [AIIB] that will focus on infrastructure on a regional basis is actually an attractive proposition, and it's not that the region is short of needs; it's short of potential projects," she added.

Lagarde signaled her support for the AIIB on April 9, saying cooperation with the AIIB "is a no-brainer".

Kim also dismissed concerns the rise of shadow banking in China remains a high risk, saying that "our own sense going forward is that the Chinese authorities are very well-equipped to deal with whatever might happen, and we don't think that the risk of a disorderly unwinding or a disorderly event related to the current sub-national indebtedness or the shadow banks is a high possibility".
