This transport privatization case describes the political complications that can accompany a privately-funded infrastructure project. The case tells the story of a Japanese construction firm and its relationship with the government of Thailand. The firm, Kumagai Gumi, is invited to build US$1 billion, 20-kilometer expressway in Bangkok, and to operate it as a toll road, under a 30-year concession contract. But a 1995 contract dispute prompts the Thai government to force Kumagai Gum first to open the road but then to sell it to Thai investors. The case allows for discussion of both a technical and political nature, focusing on the details of the contracting arrangement but also raising the question of domestic political dimensions in public projects involving non-domestic private investors.
