China's New Silk Road

China calls it the project of the century, a massive pathway of Chinese built infrastructure designed to drive trade across more than 60 countries. This new silk road, which echoes the trading routes of the past, could remake the global economy to China's advantage, and critics see it as a power grab by the communist state. The BBC's China Editor, Carrie Gracie, has travelled from the east of China to the west of Europe, to hear from people who live along the route of China's new Silk Road.
