The investments are both private and public (for example, by state-owned entities) and come from three different groups of countries: emerging economies like China, India, Brazil, South Africa, Malaysia, and South Korea; oil-rich Gulf states; and wealthy developed economies like the United States and several European countries. On average, per capita income in the countries that are the source of these investments is four times higher than in the target countries.
这类投资既有私人部门，也有公共部门（如国有实体），主要购买者是三类国家：中国、印度、巴西、南非、马来西亚和韩国等新兴经济体；波斯湾富油国；以及美国和不少欧洲国家等富有的发达国家。平均而言，投资来源国的人均收入比投资目标国高出四倍。
