Khunjerab Pass, Pakistan

AT an elevation of more than 15,000 feet (4,500 m), yaks far outnumber cargo trucks crossing over Pakistan's border with China. A lone border agent stands guard on the Pakistan side, when he has not ducked into a steel shelter to avoid wind-whipped snow.

But here in the mountains, and all the way down to the sea, China is now pouring in billions of dollars in investment, as part of a bigger project to re-create the fabled Silk Road.
