You're right. In fact, there was increased surveillance. What happened after.... There were four attacks that took place.
Of course the genesis of all of this was the very important riot that took place in Urumqi, the capital of Xinjiang, in 2009. After that, in 2013 and 2014—I was in China at the time—there was the first attack on Tiananmen Square in October in Beijing, and then a very gruesome attack, using knives, at the Kunming train station on March 1, 2014. Then there was an explosion at the Urumqi train station, and then finally a suicide car attack in an open market in Urumqi on May 22, 2014.
I had a discussion with Chinese officials in the Communist Party of China after those events to tell them that the policy they were following was the reason they were generating those attacks and that in fact they had to change the attitude. I recall saying to people in the Ministry of Foreign Affairs, “Look at the example of Canada. Here I am, a French Canadian, as ambassador in one of the most important countries in the world. Can you point out to me a Uighur ambassador that you have anywhere around the world, or a Tibetan who occupies the function of ambassador?”
I said, “You have to give better opportunities to your people while letting them protect their culture.” I said, “There is a sense of despair for what you are doing. You are creating for yourself a lot of resentment, and this will come back to haunt you.”
Of course this led to very difficult conversations, but they were not in the mood to follow any advice.
