Ethnic tensions in China's restive Xinjiang province have boiled over again, and this time the unrest has spun so much out of control that Turkey's Prime Minister Tayyip Erdogan is accusing Chinese forces of committing "genocide". What's interesting about this accusation is not only the premature and almost casual way it has been pronounced (especially given how sensitive Turkey is to the word with regard to Armenian accusations that Ottoman Turks committed the first genocide of the 20th century), but also how it contradicts other things Erdogan reportedly said on the same occasion.
