Petroliam Nasional Berhad (Petronas) is planning to sell its stakes in five offshore oilfields in Vietnam for a combined $300 million. The planned asset sale is part of the oil company’s current endeavour to streamline its assets and raise funds for expansion. Petronas also has plans to tap into North America’s shale industry. Bank of America Merrill Lynch had been appointed to find buyers for the company’s stakes in the Vietnam oilfields.
