Allen & Overy (A&O) and Allens have scored lead roles on a multibillion-dollar oil refinery project in Vietnam – touted as one of Asia’s most important energy developments.

The Nghi Son Refinery and Petrochemical Complex, Vietnam’s second refinery, will be built on a 400 hectare site in Thanh Hoa province, south of Hanoi, and will process 200,000 barrels of oil per day in the first phase – approximately 40% of Vietnam’s fuel requirements.
