Asian countries are using Public Private Partnerships (PPP) to improve infrastructure and sustain economic growth. Governments are inviting private investors to help bridge the gap between infrastructure needs and budget constraints. Taiwan, Thailand, Indonesia, and India have introduced reforms to attract private sector participation in infrastructure projects. The success of these reforms in encouraging private investment through PPP is being analyzed through case studies in each country. The goal is to understand how these partnerships can enhance infrastructure development and economic competitiveness in Asia.
