Proposals have been made that southern Dong Nai province invest in and build the Thu Thiem - Long Thanh and Bien Hoa - Vung Tau railway lines, but the province has proposed the Prime Minister assign the Ministry of Transport (MoT) as the responsible agency. Investment in the two projects totals more than VND90 trillion ($3.84 billion), so it will be necessary to mobilize additional loans from foreign organizations.
