Infrastructure Asia, a project facilitation office established by the Singapore government to support sustainable infrastructure development across the region, has signed four memorandums of understanding (MoUs) to boost sustainable infrastructure development.

Infrastructure Asia said in a statement on Tuesday that the MoUs were sealed with the Indonesia Infrastructure Guarantee Fund, the Public-Private Partnership Center of the Philippines, the Private Infrastructure Development Group and the World Bank Group at the Asia Infrastructure Forum (AIF) 2026.

The MoUs will deepen cooperation with regional and international stakeholders to improve project bankability and increase financing through innovative mechanisms to support sustainable infrastructure development. This includes working closely with partners to showcase upcoming priority projects, thereby providing Singapore’s infrastructure ecosystem with early visibility of the region’s project pipeline and facilitating access to new opportunities.

The MoUs will also support capacity building through the exchange of best practices and advisory support on project structuring.

This includes Infrastructure Asia’s collaboration with the World Bank Group on the Growing Infrastructure Course, which has equipped more than 500 regional officials and infrastructure practitioners with the knowledge and skills to better enable private sector investment in sustainable infrastructure.

In addition, at AIF 2026, the Hanoi Metropolitan Railway Management Board and Singapore Cooperation Enterprise signed a MoU to advance urban transport development.

Infrastructure Asia will support the collaboration, working closely with both partners on project development, technical advisory and capacity building initiatives.

According to the statement, Asia’s infrastructure needs are expanding rapidly, even as the landscape for infrastructure development becomes more complex and interconnected.

Global infrastructure investment estimates suggest that $106 trillion will be needed through 2040, with Asia accounting for two-thirds of that demand.

In her keynote address, Indranee Rajah, Minister in the Prime Minister’s Office, Second Minister for Finance and National Development of Singapore, highlighted the need for Asia to continue investing in climate resilient infrastructure that strengthens economic competitiveness and supports social development amid a more uncertain global environment.

She also underscored the importance of stronger public-private collaboration to move projects from ambition to delivery, and Singapore’s continued role as a trusted infrastructure financing and development hub supporting the region’s long-term infrastructure needs.
