China’s transportation sector is almost entirely run by state-owned corporations, as its development is viewed as a major driver for the country’s economic growth. In the railways subsector, there was extensive construction of new high-speed rail (HSR) lines, the total length growing by more than 2,000 km to 25,000 km in 2017. In the air transport subsector, the major players have been increasingly active in expanding their aircraft fleets to meet the rapidly growing passenger demand, especially demand for international travel. The shipping subsector is strategically important for China, since it is a major generator of growth and vital for China’s exporting industries. Investment opportunities exist mainly for companies supplying technologies and high-tech products to the sector.

China’s aviation sector is dominated by China’s four largest carriers – namely China Southern Airlines (CSA), Air China, China Eastern Airlines (CEA) and Hainan Airlines – which between them control about 80% of the market in terms of total RTK. They face little competition from foreign carriers due to airport capacity limits and airspace restrictions. Overseas carriers often enter into codeshare agreements with China’s major airlines. According to the CAAC, China had a total of 58 airlines at the end of 2017, including 43 state-controlled and 15 privately-owned. Among them there were eight allcargo airlines, ten joint venture airlines and seven publicly-listed airlines.
