Tanzania's new membership in the Asian Infrastructure Investment Bank (AIIB) could open another avenue for financing major infrastructure projects after the lender announced plans to substantially expand its annual funding.
AIIB President Zou Jiayi said the bank was targeting annual financing of up to $700 billion, arguing that governments could not meet the growing cost of infrastructure investment on their own.
Ms Zou made the remarks at the opening of the 11th Annual Meeting of the AIIB Board of Governors, attended by Tanzania's Minister for Finance, Ambassador Khamis Mussa Omar.
The meeting is Tanzania's first since the country became an AIIB shareholder in 2025, giving it a new platform to engage with a multilateral institution focused specifically on infrastructure financing.
The expansion comes as countries face rising demand for investment in transport, energy, water, digital connectivity and other infrastructure needed to support economic activity and improve access to services.
"Asia alone requires around $3 trillion annually in infrastructure investment," Ms Zou said, highlighting the financing gap facing governments across the region.
She said the scale of the requirement meant governments needed to work more closely with private investors and other development partners to mobilise the capital required for infrastructure projects.
Under its new strategic direction, AIIB has identified six priority areas: climate resilience, the new economy, digital transformation, regional connectivity, environmental protection and human-centred development.
The priorities could become particularly relevant to developing countries seeking infrastructure that can withstand climate-related shocks while also supporting digitalisation and economic transformation.
Ms Zou said AIIB would strengthen its technical expertise and develop new financial instruments as it seeks to increase both the scale and quality of its operations.
She said innovation would remain central to the bank's efforts to deliver greater development impact while maintaining financial sustainability, sound banking practices and operational efficiency.
The bank currently has 111 approved members, comprising 53 regional and 58 non-regional members, according to Ms Zou.
Since its establishment, AIIB has approved more than $76 billion for 384 infrastructure projects in its member countries.
For Tanzania, the membership adds another potential source of development finance at a time when the country is seeking substantial investment in infrastructure to support industrialisation, trade, energy access and connectivity.
The government has increasingly sought to attract both public and private capital to infrastructure projects, with financing needs extending beyond what domestic resources can comfortably provide.
AIIB's emphasis on regional connectivity could also support projects designed to improve links between Tanzania and neighbouring markets, while its focus on digital transformation and climate resilience could widen the range of projects eligible for financing.
However, access to financing will depend on individual projects meeting the bank's financing, environmental, social and financial requirements.
The annual governors' meeting provides Tanzania with an opportunity to engage directly with other AIIB members and explore areas where the bank could support the country's infrastructure priorities.
For a country seeking to sustain economic growth while expanding infrastructure, the significance of AIIB membership will ultimately be measured by the projects that secure financing and the extent to which they improve connectivity, productivity and access to essential services.
