"The opening up policy has enabled China to learn from other countries, either developed or developing. To strengthen its own capabilities, China has expanded research capacity, emphasized advanced management and increased infrastructure development. China has entered a new stage of development, with growth rate of domestic investment on infrastructure development decreasing and rapidly increasing foreign investment. China has also expanded its foreign direct investment through such international programs as the “Belt and Road Initiative” to promote economic cooperation, technological innovation, and resource sharing between regions and countries. On the basis of its own national conditions, China has taken a “small step, but fast run” rather than a “shock therapy” approach, with new policies or programs. This was first demonstrated on a small scale, and then incrementally spread to the whole country, to ensure success and reduce the trial-and-error cost as far as possible. China has increasingly realized the importance of achieving an “ecological civilization” by learning from the past and promoting an aggressive decoupling of the relationship between environmental pollution and associated loss of natural capital and economic growth, and chosen to make sustainable development a national strategy."
