China's photovoltaic solar industry has developed rapidly in recent years. This mature technology can be introduced into Africa where there is a great deal of sunshine.

By the end of 2012, China had offered aid to 53 African countries, assisting 1,000 agricultural, infrastructure construction, housing, education and healthcare projects, according to the commerce ministry. China also provided free training to 53,700 people from Africa, and sent medical teams to 42 African countries by the end of 2012.

China will continue to increase its aid to Africa and boost cooperation with African countries in many sectors including agriculture, education, clean energy, environmental protection, hydropower and solar power, according to the ministry.
