The Eastern Economic Corridor Office (EEC Office) is proposing a high-speed railway PPP linking three main airports worth 200 billion baht. “The government will provide the project detail to investors,” said Kanit Sangsubhan, secretary-general of the EEC Office. "More than 70 companies, both local and foreign, will attend the market sounding." Critics say “the project favoured the private sector because of the unusually long concession of 50 years. Critics also say the private sector would have the right to develop and profit from the SRT’s 150-rai prime plot in Bangkok’s Makkasan, as well as land along the railway, in addition to numerous privileges offered under the EEC.”
