The claim that more than 7,000 Chinese troops have been handed "de facto control" of Gilgit-Baltistan, a northern part of Kashmir, by Islamabad, has set alarm bells ringing in Delhi. India – which, like its nuclear-armed rival Pakistan, claims the entire state – has long been worried that the People's Liberation Army was working on roads and railway projects in the Karakoram mountains.
What is true is that China plans a massive highway linking western China to the port it is building at Gwadar, Pakistan, on the shore of the Arabian Sea. The benefits are obvious: the journey time from factory gate in, say, China's wild west, to container ships bound for the Gulf will be cut from weeks to a few days. Eventually it may even become a key energy supply route.
