If one image has come to define the Belt and Road Initiative (BRI), China’s ambitious, amorphous project of overseas investment, it’s the railway. Every few months or so, the media praises a new line that will supposedly connect a Chinese city with a European capital. Today it’s Budapest. Yesterday it was London. They are the newest additions to China’s iron network of transcontinental railway routes spanning Eurasia. But the vast majority of these routes are economically pointless, unlikely to operate at a profit, and driven far more by political need than market demand. In that, they’re representative of the BRI as a whole — far more driven by China’s need to promote its image, and to pander to domestic political interests, than to meet commercial demands.

The myriad trade routes that once made up the ancient silk roads were driven by raw commercial need. Traders made the dangerous journeys across steppe, mountain, and desert because of the prospect of riches. That’s not the case today. Chongqing-Duisburg, Yiwu-London, Yiwu-Madrid, Zhengzhou-Hamburg, Suzhou-Warsaw, and Xi’an-Budapest are among the more than 40 routes that now connect China with Europe. Yet out of all these, only Chongqing-Duisburg, connecting China with Germany, was created out of a genuine market need. The other routes are political creations by Beijing to nourish its relations with European states like Poland, Hungary, and Britain.

The Chongqing-Duisburg route has been described as a benchmark for the “Belt,” the part of the project that crosses Eurasia by land. (The “Road” is a series of nominally linked ports with little coherence.) But paradoxically enough, the Chongqing-Duisburg route was created before Chinese President Xi Jinping announced what has become his flagship project, then “One Belt, One Road” and now the BRI. It was an existing route reused and redeveloped by Hewlett-Packard and launched in 2011 to halve the time it took for the computing firm’s laptops to reach Europe from China by sea.

Chongqing-Duisburg could have been an example of how to create a profitable route. But instead it became political fodder. The first railway was logistically developed by HP, but the development of the routes that followed has been driven by the Chinese government. A new brand, China Railway Express, has been created as an umbrella for the 40-something Chinese routes. While the branding was a good move, expanding the number wasn’t.

Unlike the HP route, in which trains arrived in Europe full of laptops and other gadgets, the containers on the new routes come to Europe full of low-tech Chinese products — but they leave empty, as there’s little worth transporting by rail that Chinese consumers want. With only half the route effectively being used, the whole trip often loses money. For Chinese companies that export toys, home products, or decorations, the maritime route is far more profitable, because it comes at half the price tag even though it’s slower.

The Europe-China railroads are unproductive not only because of the transportation price, as each container needs to be insulated to withstand huge temperature differences, but also because Russia has imposed a ban on both the import and the transport of European food through its territory. Food is one of the product categories that can actually turn a profit on a Europe-China land run — without it, filling China-bound containers isn’t an easy job. For example, it took more than three months to refill and resend to China a train that came to London from Yiwu, although the route was heavily promoted by both a British government desperate for post-Brexit trade and a Chinese one determined to talk up the BRI.

Today, most of the BRI’s rail routes function only thanks to Chinese government subsidies. The average subsidy per trip for a 20-foot container is between $3,500 and $4,000, depending on the local government. For example, Chinese cities like Wuhan and Zhengzhou offer almost $30 million in subsidies every year to cargo companies. Thanks to this financial assistance, Chinese and Western companies can pay a more affordable price per container. Without subsidies, it would cost around $9,000 to send a 20-foot container by railway, compared with $5,000 after subsidies. Although the Chinese government is losing money on each trip, it plans to increase the yearly number of trips from around 1,900 in 2016 to 5,000 cargo trains in 2020.

So why has Beijing decided to open so many unproductive routes, subsidized by local Chinese governments? Because the Globalization 2.0.””>BRI is not just an economic project but Beijing’s main soft-power initiative, helping China promote itself as a leader of what the government terms “Globalization 2.0”. By attracting as many countries as possible in this project, Beijing can legitimize its position as the new champion of free trade and globalization, thus positioning itself as a global power. So, while the railways themselves might not be economically profitable, the hope is that they will generate goodwill, respect, and influence for China.
