Also, the ADB will be appointed financial consultant to the ECT project.
Previously, the bank extended a 350 million dollar facility for the construction of three terminals with a length of 1,200 metres.

John Keells, owner of South Asia Gateway Terminals, is likely to be given priority consideration.
