The regulatory framework for Public Private Partnership (PPP) on infrastructure varies among APEC economies. Most economies have established specific legislative or regulation at different levels as legal basis for implementing PPP procurement. There is a national PPP policy framework such as implemented in Australia, Papua New Guinea, Peru, Brunei Darussalam, and Japan. Or, a there is a specific law on PPP, as applied in Chinese Taipei, Mexico, and Vietnam. At the lower level, PPP is regulated with presidential decree such as applied in Indonesia. These laws are usually followed by technical regulations on PPP.
Other economies have not established specific laws for PPP procurement. The implementation of PPP is applied as an option of infrastructure procurement model. PPP projects are implemented under other regulations in related sectors such as public works, government procurement, or investment. Among the economies are Canada (under Financial Administration Act and Treasury Board Policy), Malaysia (under Malaysia Incorporated Policy and Privatization Policy), the Philippines (under An Act Authorizing the Financing, Construction, Operation and Maintenance of Infrastructure Projects by the Private Sector, and for Other Purposes), and Singapore (under The Government Procurement Act and Regulations).
