China has promised to invest $1bn (¬£530m) in Nigeria’s creaking railways in its latest attempt to extend its influence in Africa. The Chinese government offered the funds in the form of a soft loan to help repair old lines and install new rolling stock and equipment.
“Provision of infrastructure is critical for economic development,” Nigeria’s finance minister, Ngozi Okonjo-Iweala, said when announcing the deal, the Xinhua news agency reported yesterday. The move will consolidate Beijing’s ties to sub-Saharan Africa’s biggest oil producer, part of a strategy to court oil exporters to fuel China’s booming economy.
