PETROLIAM Nasional Bhd's (Pet ronas's) 80%-owned South African subsidiary, Engen Ltd, is eyeing marketing assets currently held by BP Plc, following the decision by the energy giant to refocus its African strategy on what it nations within the continent that offered the greatest synergies to its supply portfolio. In early March 2010, in a statement from BP and the chief executive of its African unit BP Africa, Sipho Maseko, the international oil and gas firm said it planned to sell off marketing assets in Botswana, Malawi, Namibia, Tanzania and Zambia, and focus instead on Algeria, Angola, Egypt, Libya, Mozambique and South Africa.
