If US attempts World Bank retreat, the China-led AIIB could be poised to step in – and provide a model of global cooperation

The AIIB is deeply tied to the rules-based order as displayed through its many cooperative connections with other major multilateral development banks, such as the World Bank and the Japan-led Asian Development Bank.

As such, the AIIB may present a Chinese counterpoint in a landscape where U.S. leadership is receding.

The cooperative design of the AIIB

For decades, multilateral development banks have served the important task of lending billions of dollars a year to support economic and social development.

They can be vital sources of funding for poverty reduction, inclusive economic growth and sustainable development, with a newer emphasis on climate change. These international lenders have also been remarkably durable in today’s climate of fragmentation and crisis, with member nations actively considering ways of further strengthening them.

At the same time, MDBs perennially face criticism from civil society organizations who highlight areas of weak performance and are concerned about potential downsides of the major MDBs’ greater emphasis on working more closely with the private sector. MDB expert Chris Humphrey has also noted that major “MDBs were built around a set of geopolitical and economic power relationships that are coming apart before our eyes.”

When Chinese President Xi Jinping in 2013 proposed creating the AIIB to lend for infrastructure development in Asia, there was a lot of suspicion among major nations about China’s intentions.

The Obama administration responded to the move by urging other countries not to join. Its concern was that China would use lending to gain further influence in the region, but without adhering to strong environmental and social standards.

Nonetheless, all the other major nonborrowing nations, with the exception of Japan, joined the new bank. Today, the AIIB is the second-largest multilateral development bank in terms of member countries, behind only the World Bank. It currently has 110 member nations, which translates to over 80% of the global population. With US$100 billion in capital, it is one of the medium-sized multilateral lenders.

From the get-go, the AIIB was designed to be cooperative. Jin Liqun, who became the bank’s first president, is a longtime multilateralist with a long career at China’s finance ministry and past positions on the boards of the World Bank and the Global Environmental Facility, as well as a vice presidency of the Asian Development Bank.

The international group of experts that helped design the AIIB also included former executive directors and staff from the IMF and other development banks, as well as two Americans with long careers at the World Bank who played leading roles in designing the bank’s articles of agreement and its environmental and social framework.

How the AIIB took its cue from others

The bank fits into the landscape of other multilateral development banks in a variety of ways. The AIIB’s charter is directly modeled on the Asian Development Bank’s foundation, and built into the AIIB’s charter is the bank’s mission of promoting “regional cooperation and partnership in addressing development challenges.”

The AIIB shares similar norms and policies with other major multilateral development banks, including its environmental and social standards.

Alongside borrowing foundational principles, the AIIB also works in close conjunction with its peers. The World Bank initially ran the AIIB’s treasury operations. The AIIB has also co-financed a high percentage of its projects with other multilateral development banks, particularly in its first years.

In a recent sign of cooperation, in 2023, a deal between the AIIB and World Bank’s International Bank for Reconstruction and Development (IBRD) saw the AIIB issue up to $1 billion in guarantees against IBRD sovereign-backed loans. This increased the IBRD’s ability to lend more money, while diversifying the AIIB’s loan portfolio.

As of Feb. 6, 2025, the AIIB has 306 approved projects totaling $59 billion. Energy and transportation are its two largest sectors of lending. Recently approved projects include loans to support wind power plants in Uzbekistan and Kazakhstan, and a solar plant in India. India, which has a bumpy relationship with China, is one of the bank’s largest borrowers, along with Turkey and Indonesia.

Cooperating and competing with China

From its birth until recently, the multilateral AIIB has repeatedly distinguished itself from China’s bilateral initiatives. Chief among those is China’s Belt and Road Initiative, an umbrella term for infrastructure lending by Chinese institutions that has been criticized for lacking transparency and accountability.

Indeed, some Belt and Road Initiative-linked projects have faced concerns about corruption, costs and the opacity of the loan agreements.

In the past several years, the AIIB has made more mention of synergy with Belt and Road lenders, and the bank now hosts the secretariat of a facility, the Multilateral Cooperation Center for Development Finance, that offers grants and support to developing countries seeking to finance infrastructure in countries where Belt and Road lending takes place. This may blur the line between the AIIB and lending under the Belt and Road umbrella, but it does not appear to weaken the bank’s standards.

Concerns about the level of Chinese government influence at the AIIB are not new. Canada froze its ties with the bank in June 2023, pending a review of allegations by a Canadian staff member, who dramatically quit after accusing the bank of being dominated by members of China’s Communist Party.

No other member nations expressed such concern, and Canada has not yet published any review. A group of AIIB executive directors oversaw an internal review that found no evidence to support the allegations.

As the new U.S. administration formulates its policies toward China, it would do well to take into account the variation in China’s strategies in global economic governance, as a recognition of areas of cooperation, competition and conflict requires more nuanced responses. In many areas, the U.S. will both cooperate and compete with China.

Paradoxically, any moves by the Trump administration to pull back from multilateral organizations may leave the AIIB, whether or not it is an anomaly, in a position to offer a better model of cooperation than leading multilateral development banks with a powerful U.S. role.
