As China’s largest oil and gas producer，CNPC is the first to invest in Africa and the largest investor of China’s oil enterprises in Africa. At present，CNPC hosts 25 energy cooperation projects in Africa，with annual production of 30 million tonnes of oil，refining capacity of 5.6 million tonnes，3600 km pipelines and oil transportation capacity of 35 million tonnes. CNPC has established a relatively complete oil industry chain in Africa. Meanwhile，Chinese oil enterprises in Africa face many challenges from both the outside and the within，which including，among others，the rising terrorist risks，political instability，the downward trend of oil price，and poor operations of the enterprises themselves. To safeguard China’s energy security and to solve the problems of oil enterprises，governmental organizations and enterprises concerned should improve their performance from every link to promote the development of China-Africa energy cooperation. The government should strengthen the follow-up and study of Africa’s investment environment from the state level，and set up and improve the security responding mechanism. Diplomatic and commercial institutions should sign investment protection agreements with African countries. State-owned assets supervision and administration authority should enhance the degree of engagement of national strategy with enterprises’ projects. Risk information should be provided in time to enterprises. And government should work together with enterprises to ensure the correct understanding of China-Africa energy cooperation.
