Over the past few years, China's railway network, especially high-speed rail, has undergone dramatic change. From 2011 to 2015, China invested 3.58 trillion yuan to build 30,000 km of railway. By the end of this year, the nation's total railway length will reach 124,000 km, including 20,000 km of high-speed railway, accounting for 65 percent of the world's total high-speed rail.

In July, the National Development and Reform Commission issued an updated national railway development plan envisioning a 175,000-km rail network by the end of 2025, with 38,000 km of high-speed rail.

However, the network still faces challenges, especially in the less-developed western part of China. Yang says he is confident that lines in western China will eventually become profitable.

"Plus, building high-speed railways in less-developed regions is not only about recouping investment. It is part of the big project of rejuvenating the whole region and the country's economy.

The high-speed rail linking Beijing and Shanghai showed a profit last year, Xinhua News Agency reported in July, quoting Tianjin Railway Construction Co, a shareholder of Beijing-Shanghai High-Speed Railway Co.

Yang Hao, a professor of rail transportation at Beijing Jiaotong University, says the economic returns of a high-speed railway network shouldn't be judged solely on whether lines are profitable, since these railways can leverage the development of such industries as tourism, logistics and real estate.

According to China Railway Corp, construction began on Dec 29 on a high-speed line linking Guiyang, Guizhou province - a transportation hub connecting members of the Association of Southeast Asian Nations -and Nanning, capital of the Guangxi Zhuang autonomous region.

The 482-km line will connect the Shanghai-Kunming railway and the Chengdu-Guiyang railway to the north, and will also link to southern coastal areas including Hainan province and Guangzhou, Guangdong province.

The new will accelerate communication between China and ASEAN countries and play an important role in the Belt and Road Initiative.
