It has not taken long for the wheels to come off the Belt and Road Initiative. As recently as May 2017, China’s leader Xi Jinping stood in Beijing before a hall of nearly 30 heads of state and delegates from over 130 countries and proclaimed “a project of the century”.

This was not hyperbole. China has promised to spend about $1tn on building infrastructure in mainly developing countries around the world — and finance almost all of this through its own financial institutions. Adjusted for inflation, this total was roughly seven times what the US spent through the Marshall Plan to rebuild Europe after the second world war, according to Jonathan Hillman, author of The Emperor’s New Road.

But according to data published this week, the reality is deviating sharply from Mr Xi’s script. What was conceived as the world’s biggest development program is unraveling into what could become China’s first overseas debt crisis. Lending by the Chinese financial institutions that drive the Belt and Road, along with bilateral support to governments, has fallen off a cliff, and Beijing finds itself mired in debt renegotiations with a host of countries.

“This is all part of China’s education as a rising power,” says Mr Hillman, a senior fellow at Washington-based think-tank CSIS. “It has taken a flawed model that appeared to work at home, building large infrastructure projects, and hubristically tried to apply that abroad. ”
