Some predicable replies here, generally following the official US propaganda line on China.
As someone who has lived in China and visited many times over the years, I can tell you it's not the way it's portrayed in the west.
Casting it in a "warmongering" light is a form of projection, when it's actually the USA that is threatening China.
No country is perfect, but lack of understanding of China's cultural history, fear of the 'other', and ignoring the fact that the majority of Chinese people support the CCP, is not the way to foster better relations.
My advice, to those who trash China, is to visit the country yourself. You will be very surprised by what you learn and see there.
