As the Asian Infrastructure Investment Bank (AIIB) and New Development Bank (NDB) mark their tenth anniversaries, it is worth asking what difference these institutions have made.
Following their launch, many observers touted the transformative potential of both institutions. In 2016, Nobel Prize-winning economist Joseph Stiglitz argued that the NDB ‘reflects a fundamental change in global economic and political power’. Daniel C K Chow claimed ‘the rise of the AIIB could be the first indication that China will succeed in its quest to displace the United States as the final arbiter of the rules of international trade and finance in the twenty-first century’.
A decade in, these claims are belied by a more prosaic reality. While the AIIB and NDB have some distinctive features, both fit comfortably within the existing family of multilateral development banks (MDBs), largely mirroring and complementing their predecessors. While each bank has grown and matured, neither has lived up to the promise cited by their supporters or the peril predicted by their critics.
There are commonalities in the structure and evolution of the two banks. Both focus on infrastructure development, with a growing emphasis on green investment, though the strength of their green credentials has been questioned. Both have expanded their membership since inception: from 57 to 111 countries for the AIIB and from 5 to 14 for the NDB. Both have also matured institutionally through leadership transitions, the opening of new offices and expansion beyond sovereign lending into loan guarantees, equity investments and private-sector financing.
In other ways, the two banks differ. While the AIIB focuses on Asia, it lends globally. Its membership includes major Western donor countries, but China accounts for around 30 per cent of the bank’s capital. After initially relying on larger MDBs for technical support and co-financed projects, the AIIB has strengthened its own capacity to oversee project preparation and implementation. It has also developed a research arm, though it cannot rival the World Bank’s premier status as a ‘knowledge bank’.
One important institutional difference from legacy MDBs is that the AIIB has adopted a strong-president, weak-board model, which has led to complaints about limited transparency and accountability. But in most other respects, the AIIB’s policies, procedures and structure closely mimic existing MDB norms. This fits longstanding patterns in which the highly institutionalised regime of multilateral development finance exerts strong socialisation pressures on new entrants. Emulation of existing norms also reflects the influence of the AIIB’s European members.
The relatively unexceptional character of the AIIB is notable for a Chinese-led bank, yet can be explained in terms of China’s motivations. China seeks an expanded role in global governance to gain relational power within global elite networks. A China-led bank that largely conforms to existing norms also helps reassure other countries that a rising China can be a source of stability rather than a threat. China’s commitment to the AIIB, alongside its broader investments in global governance, offers a sharp contrast with the United States’ recent retreat from leadership of the rules-based international order.
If the AIIB highlighted China’s role as, in Robert Zoellick’s memorable phrase, a ‘responsible stakeholder’, the NDB serves instead to reinforce China’s claim to leadership of the Global South. A product of collaboration among BRICS countries, the NDB symbolises the aspiration of developing countries to greater autonomy in steering the global development agenda. The NDB is a borrower-led, South–South bank that lends only to member countries, while excluding Western donors.
There are some ways that both institutions depart from the norms of Western-led MDBs, such as the weaker application of political and governance conditionality. In keeping with its members’ desire to reduce dependence on the Western-dominated financial system, the NDB has increasingly shifted to local-currency financing on both the borrowing and lending sides, with close to one third of loans denominated in Chinese renminbi, South African rand or Indian rupees.
Yet there are real limits on the NDB’s autonomy. The bank is dependent on the global bond market and the blessing of Western credit rating agencies. To avoid sanctions and maintain its high credit rating, for instance, the NDB has been compelled to suspend loans to Russia since 2022, despite Russia being a founding member of the BRICS grouping.
The NDB is also hobbled by its relatively small scale and limited institutional capacity. Since 2016, the bank has approved only 139 projects valued at US$42.9 billion. The NDB employs fewer than 500 professional staff, compared with close to 20,000 at the World Bank. It also lacks independent safeguard policies, instead leaning on borrowing country standards. A 2024 internal evaluation found weaknesses in proposal assessment and project supervision. Despite its symbolic significance, the NDB remains a bare-bones operation with limited impact.
The AIIB is larger, having approved US$75.8 billion across 384 projects as of June 2026. Yet both banks are dwarfed by legacy MDBs. In 2024, the NDB and the AIIB committed US$4.5 billion and US$8.4 billion, respectively, compared with US$24.3 billion for the Asian Development Bank and US$117.5 billion for the World Bank Group.
While the AIIB and NDB have expanded funding options for infrastructure financing and enhanced Global South representation, they are less institutionally transformative than early claims suggested. Like China itself, they partly accommodate and partly challenge the global development finance regime and the broader liberal order.
