Asian investment in Africa hit record levels last year, reaching US$90-billion, but was concentrated on the energy sector and needs greater diversity according to a recent UN report. Singapore, India and Malaysia were the top Asian originators of foreign investment in Africa while China was becoming a major player. Many foreign countries were investing more heavily in Africa in an attempt to secure future energy needs. One benefit of Asian investment was that much of its was concentrated on "greenfield" projects, that is new factories rather than in mergers and acquisitions of existing industry, said the report.
