MPAC faces both challenges and opportunities in developing infrastructure through public-private partnerships (PPPs). Several Southeast Asian countries have established PPP units and regulatory frameworks, but challenges remain around institutional fragmentation, unclear procedures, and foreign ownership restrictions of land. Cross-border infrastructure projects offer opportunities for large-scale development but require navigating multiple authorities. While countries like Malaysia and Singapore have more streamlined PPP processes, others would benefit from reducing uncertainty and establishing clearer timelines and project valuation guidelines to better facilitate private sector participation in infrastructure development through PPPs.
