It is important to recognize China's argument in favour of its aggressiveness.
China has often pointed out that as a country with a much lower per capita income, it has every right to go after its interest in closing the gap with wealthier countries and to use whatever mechanisms are available to do so. China is insulted by suggestions that its attempt to bring more wealth to its people ought to be compared to the actions of a country such as the US that already has high wealth and means to keep its near monopoly on world power intact.
In spite of whatever else you might say about this argument it is at once compelling from a historical justice perspective and an argument that you have every reason to believe Chinese leaders hold dear to their hearts.
Regardless of the state of China's development of political accountability, this factor must be considered.
Another geopolitical point speaks to Chinese attitudes and history. China has a big domestic market. It has had a tendency to disregard the importance of anything outside its borders and take an isolationist posture. Due to its size it can afford to do this provided it has everything it wants. The swing from engagement to isolation is something China has been involved in for centuries. I am not convinced that those upset at China's demand for a fair seat at the table would really prefer China to be isolationist. Certainly many have claimed that China's role as a counterweight to the US has been welcomed.
As for the political developments in China, I enjoy the speculation I hear from people I know but it really amounts to just that-- there is little infromation out there. This rather than a lack of interest may be behind the few responses to Wilf's questions. My guess is there is a significant number of people who want change but also want to manage it carefully. It will be itneresting to see how they do. I have been long afraid that China's changes could result in more and more areas where the government gives up an essential role in society and the economy. They are right to be careful-- rampant capitalism is not a solution either.
