The purpose of Chinese leaders' promotion of China's railway projects abroad is to boost cooperation, and achieve common development and prosperity.

With Chinese high-speed railways and standards globally recognized, related projects have become a highlight in production capacity cooperation between China and other countries, according to experts.

Building railways abroad and exporting related equipment and technologies lead to all-win situations for both China and its foreign partners, as such cooperation will facilitate China's endeavor to upgrade its national economy and allow partner countries to enjoy all the benefits of these projects at lower costs.

Chinese companies and those in developed nations may work together to produce high-quality, inexpensive equipment and develop huge markets in third-party countries, Li recently told the annual meeting of the Summer Davos Forum in China's northeast port city of Dalian.
