A New Silk Road or Steel Trap?

Vietnam’s ambitious rail link to China could turbocharge trade, but runs the risk of Hanoi becoming more entangled in Beijing’s embrace.

Vietnam’s National Assembly has given the green light to a colossal $8.37 billion railway project linking its northern port city of Hai Phong to Lao Cai, on the border with China’s Yunnan province. Slated for completion by 2030, the 390-kilometer rail link promises to boost economic integration, cut logistics costs and facilitate trade.

The railway is part of Vietnam’s ‘Two Corridors, One Belt’ initiative, itself a nod to China’s Belt and Road Initiative (BRI). On paper, it should unlock new efficiencies for manufacturers and exporters. The new line will serve industrial powerhouses home to global firms like Samsung and Foxconn, whose supply chains rely on steady flows of components from China. By improving transit times and reducing Vietnam’s reliance on its congested and outdated road network, the railway ideally ought to make Vietnam more competitive.

But while Chinese investment in infrastructure has transformed logistics across Southeast Asia (as seen in Laos and Thailand), such projects come with a strategic price tag. China has pledged financing for the new Vietnamese railway, raising concerns about debt dependency. The China-Laos Railway, operational since 2021, has slashed transportation costs but has also saddled Laos with billions in debt, strengthening Beijing’s leverage over Vientiane. Could Vietnam, a country historically wary of Chinese dominance, be heading down the same track?

China has been Vietnam’s largest trading partner for years, but their relationship is fraught with tensions. Maritime disputes in the South China Sea have kept diplomatic ties on edge, even as trade and investment deepen. Vietnam’s ‘bamboo diplomacy’ - balancing China’s economic pull with strategic ties to the United States and other powers - will be sorely tested as this railway project unfolds. Washington and Tokyo, both keen on bolstering Hanoi as an alternative to Beijing’s economic hegemony, will watch closely.

Beyond geopolitics, there are domestic challenges. Vietnam’s infrastructure projects have a long history of delays and cost overruns, and this railway is unlikely to be an exception. A feasibility study is set to begin this year, yet major infrastructure efforts in Vietnam often get bogged down in bureaucratic inertia and funding gaps. The country’s recent approval of a $67 billion high-speed rail project from Hanoi to Ho Chi Minh City further raises questions about resource allocation and execution.

Then there’s the economic calculus. The new railway will reportedly serve 20 percent of Vietnam’s population and nearly 25 percent of its GDP, but critics argue that the cost-benefit analysis remains opaque. Vietnam’s existing rail network, much of it dating back to the French colonial era, has long suffered from neglect. Trains currently crawl along outdated tracks at speeds of just 50 km/h. The new line promises speeds of up to 160 km/h, but will this be enough to justify the price tag?

For Beijing, the railway’s strategic benefits are clear. The line will integrate seamlessly into the China-Europe freight network, allowing Vietnamese goods to reach European markets faster via China’s growing rail corridors. More crucially, it cements Beijing’s influence in Southeast Asia, knitting Vietnam tighter into China’s economic orbit.

Vietnam, however, has little interest in becoming a mere waypoint in China’s grand design. It seeks to harness Chinese investment without becoming over-reliant, maintaining its status as a key node in global supply chains that stretch beyond China. The country has aggressively courted Japanese and Western investment as a hedge against Beijing’s dominance.

A smoother transport link with China could make Vietnam even more attractive to investors, but could also deepen its dependence on Chinese raw materials and logistics infrastructure. If managed carefully, Vietnam’s new railway could be a boon, slashing transport times and reinforcing its status as Southeast Asia’s rising economic star. But if Beijing’s financing terms prove onerous, or if geopolitical tensions escalate, the project could turn into a costly albatross.
