Except the world is not in the 19th Century anymore.
Much of China's schism with the west is - from Chinese perspective, that China is not doing anything that the western (and Japanese) imperial power didn't themselves do back in the 18th and 19th century - in fact, with some of that western imperialism applied towards China. So China tend to reject western objection to Chinese policies as hypocritical in a historical context.
But, we don't live in the 19th Century anymore. And what China is doing in its exercise of modern imperialism is clearly not acceptable in the 21st Century.
The trick is how do we get China off it's 19th Century based mindset and join the 21st Century?

Capitalism, consumerism, and availability of information to the average person in China.
Oh and as the countries standard of living for the average Chinese citizen rises the desire for more information will rise too.
They have their steps and troubles to go through, but if the curve up for the average citizen rises quickly it will create the conditions their government will not be able to stifle or control.
Capitalism, consumerism, and availability to open information will change China.
