Over 200%. That number is China's debt relative to its GDP, and its an unsustainably high number. In 10 to 15 years China's debt will be insurmountable unless painful steps are taken now to rebalance the Chinese economy. The possibility of demise for China is the intersection between those painful steps, and the CCP's fear those steps will threaten its hold on power - the entire political system actually. Great disparity in China has always led to great upheaval, which I suppose is what is really meant when people use the word "Demise".

Is that debt mostly owed to itself?

If it is then it doesn't matter much. Especially given their authoritarian political and economic model.
