The economic and trade cooperation between China and Africa has improved infrastructure, created jobs, and enhanced people's livelihood in Africa, while having helped Chinese enterprises, products, and standards go abroad, a senior commerce official said Tuesday.

"The cooperation has no political strings attached and is of win-win and equal nature," Vice Minister of Commerce Qian Keming told a press conference.

Qian also said that Chinese investments in Africa are largely in the form of infrastructure projects and are valuable assets that will bring benefits to Africa's future economic growth.

While making investments, China will select more projects that generate economic benefits, create jobs, and increase taxes and exports, he said.

Looking forward, China will focus on helping strengthen Africa's internal drive for economic development, and share its experience in infrastructure construction with African countries, Qian said.
