Take note of these Chinese troops in Kashmir, with Islamabad's apparent permission, securing their route to the western sea with a new highway and -- India fears -- perhaps a railroad.
China's railroad made an appearance in the Grand Strategy post.
[China has] just built a hugely expensive railroad through their Xinjiang province, in part to be able to access some of those buried resources in Afghanistan. They can't afford for the region to fall into chaos such that they cannot extract resources. They also wish to compete with Pakistan, Iran and especially India for influence.
Watch this development, as it is both expected and yet still quite interesting.
