These maps show how far China’s freight railways are stretching across Asia

BEIJING — In the last two years, China has announced the opening of new freight train lines, while cross-border railways have become a feature in President Xi Jinping‘s meetings with regional leaders.

It’s all part of Beijing’s Belt and Road initiative, a complex network of infrastructure projects connecting China to its trading partners.

Here’s a look at where the rail lines are being built across the Asian continent.

The projects include high-speed passenger trains.

In April, China’s national rail ticketing app opened online bookings for a 10.5-hour train ride from Yunnan province to the capital of Laos. If all goes as planned, that route will one day connect to the Thai capital of Bangkok and Phnom Penh, Cambodia’s riverside capital.

In the last six months, China also opened freight train lines to Laos, Thailand and Vietnam, according to state media.

Far in the north, China last year opened a railway bridge between the remote province of Heilongjiang and Russia. New rail routes to transport coal from Mongolian mines to China are underway, according to state media.

Those freight lines are in addition to China’s relatively older rail network through central Asia — connecting Yiwu in eastern China to London.

While it’s difficult to verify how operational all the rail lines are, official reports offer a glimpse at how China’s Belt and Road ambitions are panning out.

CNBC analyzed the reports to create the following schematic diagrams of the railways, built and planned, by region:

China’s Belt and Road Initiative was launched in 2013 at the beginning of Xi’s presidency. The program is widely seen as Beijing’s effort to boost global influence through the development of rail, sea and other transportation routes running from Asia to Europe and Africa.

“Splitting Europe from the U.S., at least to the extent possible, is an important foreign policy objective for China and deeper economic integration fostered by stronger rail linkages would help,” said Stephen Olson, senior research fellow at the Hinrich Foundation.

Similarly, “part of China’s motivation in constructing rail links in ASEAN is to place China more at the heart of regional trade,” he said, referring to the 10-member Association of Southeast Asian Nations bloc.

Olson said that while rail could be “game changing” for a landlocked economy such as Laos, the onus is also on the destination country to develop logistics and other infrastructure to fully utilize the new rail lines for trade. 

Since 2013, Belt and Road-related construction contracts have totaled $573 billion, according to estimates released in January by Christoph Nedopil, founding director of the Green Finance and Development Center at Fudan University in Shanghai. Including non-financial investments, that figure rises to nearly $1 trillion, the report said.

Critics say that through the massive infrastructure project, China has forced developing nations to take on high debt while benefiting Chinese companies, often state-owned entities.

“Analysis of the impact of the freight lines will be indivisible from an analysis of the overall impact of closer trade relations with China,” Olson said.

“For some countries this might work out better than for others. China’s economy is far larger than any single economy in ASEAN and that creates leverage that can sometimes result in unbalanced and unsustainable trade relationships.”

In an annual report in March, China’s National Development and Reform Commission, the top economic planning agency, highlighted progress on international rail construction. The commission also said it was cognizant of risks.

“We developed major overseas projects while guarding against related risks, helped enterprises guard against and defuse overseas investment risks, and worked faster to build a comprehensive service platform for monitoring, assessment, and early warning of risks related to overseas projects.”

China is set to hold the third Belt and Road forum at an unspecified time this year. Xi has invited Russian President Vladimir Putin to attend, state media said.
