Chinese enterprises are also expanding their investment areas constantly. Besides traditional industries such as energy, household appliances, light industry and agriculture, other sectors such as basic infrastructure construction, telecommunications, automobiles, mechanical and electrical products and tourism have become the new areas for investment. Currently, China has more than 800 enterprises in Africa with investment projects covering 48 African countries and regions.

Statistics from the Ministry of Commerce show that by the end of 2007, China's existing direct investment in Africa hit $4.46 billion with the figure of the first six months of 2008 reaching $310 million. Chinese enterprises have constructed a batch of production projects in light industry, textiles and household appliances, exerting positive influences on improving local production and technology levels, which also contribute to tax revenue and employment. In 2007, Chinese non-financial enterprises paid total taxes of $260 million in Africa and employed 59,000 local staffers.

To date, China has signed the Bilateral Agreement on Investment Promotion and Protection with 29 African countries and the Agreement for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income with nine others. Agreements with other countries under consultation are also in constant progress. All these have laid a sound policy and legal environment for Chinese and African enterprises to conduct investment and cooperation.

Chinese enterprises are mainly engaged in house construction, petrochemicals, electricity, transportation, telecommunications, irrigation projects and other fields involved in national economies, project contracting and labor cooperation with African countries. Famous for their high efficiency, Chinese enterprises have constructed influential landmark buildings such as the Pine Club of Algeria, winning praise from people from all walks of life on the continent.

Sino-African cooperation also made breakthrough in other fields. In May 2007, China successfully sent a Nigerian satellite, NIGCOMSAT-1, into space. This was the first time for China to provide a package of commercial satellite launching services for an international client, which boosts its progress in terms of satellite application, ground communications and telecommunications network and economic development in Africa. In November that year, the Industrial and Commercial Bank of China bought 20 percent of the shares of the Standard Bank of South Africa, the largest bank in Africa, for $5.5 billion, starting the large-scale cooperation between China and Africa in the financial field.
