Expanding infrastructure to facilitate passenger and freight transportThe rapid development of the road network, especially the highways, is necessary to support the country’s growing road freight traffic, which surpassed 39 billion metric tons in 2021. On the railroad side, Inner Mongolia was the region with not only the longest operating railroad network but also the second largest rail freight volume, with more than 690 million metric tons of cargo in 2020. However, the passenger rail section presented a different picture, with Guangdong carrying the most rail passengers in the country.
By the end of 2021, China owned nine airports with an annual passenger throughput of more than 30 million passengers and seven with an annual cargo throughput of more than 500,000 metric tons. Yangtze river is the main river for inland water transport in China, with a total inland waterway length of approximately 64,700 kilometers, which far exceeded the length of other rivers combined. Yangtze River Delta, centered on the Shanghai Port and surrounded by the ports of Jiangsu and Zhejiang provinces, is the largest and busiest port cluster in China and worldwide.
