From today's Globe & Mail:
In the wake of violent rioting in the western city of Urumqi back in July, Chinese authorities took a radical step: cutting off all Internet, text-messaging and international telephone services in Xinjiang, a restive province home to 21 million people.
Nearly four months later – and despite official assertions that calm has returned to Xinjiang following the ethnic violence that left almost 200 people dead – the cut-off remains in place, effectively severing the predominantly Uyghur Muslim region from communicating with the rest of the planet.
It's only called "collective punishment" if Israel does it.
