why is there no terrorism in China?

Lots of terrorism is occuring in China its just that, people don't choose to read the international news sections of their media much, or that they only focus in on that it says about China or what China is saying.

Lately, Myanmar has asked China for aid in stopping terrorist forces using Chinese soil as a base to launch attacks. Over the last year their have been several high profile attacks on train and police stations.

Brutal attacks on innocent civilians are going on in China on a regular basis, refer similar stories from www.molihua.org.

China Communist Party never reports negative news.

There is, but medias will only share good news instead. They don't like to ruin China's image to the people and make people believe that it's the best country.

There is, you just never hear about it.

There was one at Tiananmen a couple of year ago, Beijing airport was hit by a lone man, there is a LOT of terrorism in Kunming, or whatever the place is called.

Because you are not there

There is. China's state media doesn't necessarily report it.
