Private investment in transport infrastructure development has been sought since 1968 to meet the growing need for capacity expansion and improvement for which sufficient budget allocations were not available. As shown in table 1, by August 1994, 93 projects costing US$ 2.7 billion were implemented with private investment. As a comprehensive legal system supporting private investment in infrastructure had not been established at this time, each project was promoted under the laws governing each sector such as the Road Act, Harbour Act, etc. These investments, however, were of limited size, did not cover all sectors, and operation and management of these facilities by the private party that invested in their construction were not permitted.
