I think many people are seeing the world at where they stand, not taking into consideration of others' position. China and US are at different development stage. The idea of political system is very misleading. I don't think sanction is right, and I don't think sanction does anything good to countries being sanctioned. And I believe when people's living standard rise, every country will be more democratic and fair. Is China's political system the reason US is not happy about? I don't think so. It was the same political system 10 years ago, 20 years ago. The reason is that China is stronger now. Unless US has a direct influence on China, it will not tolerate a competitor regardless the political system.
