China's high-speed rail has covered more than 95 percent of cities with a population of 1 million by the end of 2020, an official said at a news conference on Tuesday.

China's highways already cover more than 98 percent of cities with 200,000 people, and civilian airports cover more than 92 percent of prefectural-level cities, the Ministry of Transport Minister Li Xiaopeng said.

Li said China is forming a comprehensive three-dimensional transportation network with railroads as the backbone, roads as the foundation, and water transport and civil aviation playing an advantage.

By the end of 2020, China's railroad mileage reached 146,000 kilometers, including 38,000 kilometers of high-speed railroads.

The total mileage of roads in China reached 5,198,100 km, including 160,000 km of high-speed rail, which is the largest in the world.
