How China is building railways in a bid to fast-track diplomacy

On the desolate northern outskirts of the Laotian capital Vientiane, a grand new railway station with a traditional curved roof seems to be sending a message: this country is going places.

From here, a Chinese-built railway line costing nearly US$6 billion connects Laos - one of the region's poorest nations - with China, the world's second largest economy. The Laotian leadership hopes it will bring new jobs and foreign investment, but also transformation for the only landlocked country in Southeast Asia.

The railway line stretches some 1,035km (about 640 miles) from Vientiane to Kunming, capital of fast-growing Yunnan province in China's southwest. It is the first leg of a trans-Asian link that policymakers in Beijing have long envisioned will extend China's vast railway network to Southeast Asia, a region now crucial to its diplomatic and economic agenda.

From Southeast Asia to Central Europe and Africa, railway diplomacy is a key part of China's global infrastructure investment plan, the Belt and Road Initiative. Beijing touts it as an alternative model for economic development, especially in developing countries struggling with a low standard of living and lacking in infrastructure.

China does have an edge when it comes to building railways - it had some 155,000km of them as of the end of last year. That includes 42,000km of high-speed railway line - the most in the world.

As such, building railways has been high on Beijing's agenda since it announced the multibillion-dollar belt and road plan in 2013, according to Yu Hong, a senior research fellow at the National University of Singapore's East Asian Institute.

"The core of the belt and road is connectivity, and China has some of the world's best railway infrastructure," Yu said.

The China-Laos Railway was announced in 2010 and construction began at the end of 2015, with the line up and running six years later. It is seen as a flagship belt and road project.

The railway line cuts a swathe through the jungle-covered mountains of northern Laos, and Chinese workers and engineers had to excavate 167 tunnels and build 301 bridges to make it happen.

China provided nearly everything - most of the loans, the technology, the trains, ticketing systems, wireless network antennas and even training for the Laotian attendants.
