Chinese officials said on Aug 24 that significant improvements have been made to rural transportation since 2012, and are promising a greater focus on safer and greener travel.

Since 2012, 1.2 million kilometers of roads have been built or upgraded in poorer areas, covering some 70,000 villages, new data from the Ministry of Transport showed.

Transportation officials told a news conference that new railway lines and airports have been extended to the formerly most impoverished regions.

"A new airport in remote places in Xinjiang, Qinghai or Inner Mongolia, can shorten the trip to provincial capitals by 4 to 18 hours," said Dong Zhiyi, deputy director of Civil Aviation Administration of China.

"All airports in poor areas now have at least one daily flight to the provincial capital, and one transfer at most can bring everyone to an international airport hub in the country."

The progress has solved the decade-long headache of transportation problems in poorer areas by building an extensive network that benefits both rural and urban residents, said Li Xiaopeng, minister of transport.

"We are no doubt a country with a huge transportation network, but there's a long way to build it into a strong one," Li pointed out. "To do that, we should first shift the priority from speed and scale to quality and efficiency."

Officials said the next phase will be to promote safer and greener development in the transportation sector.

Statistics released by the ministry showed that by the end of 2020, the number of new energy buses rose to 466,000, accounting for 66.2 percent of total urban buses. The national railway's electrification rate reached 74.9 percent.

More information was released on Aug 24 about the second United Nations Global Sustainable Transport Conference to be held in Beijing from Oct 14 to 16.

The conference will be attended virtually by transport ministers across the world, but their ambassadors to China will attend in person, Li revealed.

Apart from the opening and closing ceremonies, there will be ministerial forums, and plenary meetings, he said. "All preparations are proceeding in an orderly manner."

The theme of the UN conference is "Sustainable Transportation, Sustainable Development."

"Poverty reduction, people's livelihood, green development, interconnectivity and regional development; these are the areas we need to focus on when we talk about sustainability in transportation," Li explained.
