Against this background, China proposed the Belt and Road Initiative in 2013. The basic objective is to build the infrastructure connecting Eurasia and Africa, to form a community of common destiny and responsibility, and achieve mutual benefits and win-win results. As the initiator, China has four comparative advantages. First of all, China's production capacity in infrastructure construction accounts for more than half of the world's total, and over the years it has cultivated a competitive engineering and construction team; secondly, China has 3 trillion foreign exchange reserves and high saving, which can be used to support Infrastructure construction; thirdly, the developing countries could achieve successful transformation by seizing the window period while the labor-intensive industries in China are transferring out; fourthly, the experience of China transferring from an agricultural economy to a modernized has reference value for developing countries. The Belt and Road initiative not only brings opportunities for developing countries, but also benefits other countries. It provides demand for resource-producing countries, and the development of developing countries creates demand for high-income countries. Therefore, it can provide new development opportunities for international development and promote common prosperity of the world.
