BBS Joint Venture was chosen for the projects as it offered the highest returns to the state from among rival bids.
The BBS Joint Venture includes Bangkok Airways (which has a 45 per cent stake), BTS Group Holdings (35 per cent) and Sino-Thai Engineering and Construction (20 per cent).
On June 2, the Cabinet agreed with the result of the private-sector selection to join the project and assigned the EEC Policy Committee to sign the joint venture with the selected companies.
U-Tapao International Aviation Ltd, which has been established from the joint venture, is reportedly ready to sign the contract with the committee in June.
