As for all the prognostications in between—better to ignore them.

Life Living Next to a Belt and Road Project

A lot has been written about China’s multibillion-dollar Belt and Road Initiative. Economists have debated the debt dynamics, political scientists have analyzed how it fits geopolitically, and climate experts have decried the greenhouse gas emissions China is adding to the atmosphere.
