At the beginning of 20 17, the national development and reform commission and the 13 department established the working mechanism of PPP, promoted the PPP model in countries along the Belt and Road, and supplemented the funding gap for construction with social capital.

The state provides funds for the construction of the "Belt and Road" through the establishment of the Silk Road Fund and AIIB. After years of continuous efforts, the central enterprises have achieved an average annual investment growth of 15% and an average annual sales revenue growth of 4.5% in the process of "going global". Among them, the most widely known is our "Batie".

In fact, since 1990, many developing countries in China have introduced the PPP model in the field of infrastructure. This is mainly because developing China countries have implemented the open policy to solve the problems of insufficient infrastructure supply and inefficient domestic investment.

Overseas projects are generally divided into complete sets of projects (projects), general materials (goods), technical cooperation and training (services), cash and other types.

Over the past 50 years, the scale of China's foreign aid projects has grown from small to large, and the categories have gradually increased, with a wide range of industries. Compared with other aid projects, foreign aid projects have a long construction period and large investment. Project construction expenditure accounts for a large proportion of China's total foreign aid expenditure, and more social capital injection has also accelerated the economic and social development of developing China countries.
