I am not going to listen to arguments based on events from 200 years ago. My family were being starved in Ireland back then.
China was a closed nation for a very long time. Any developments in China are down to China themselves. Do you even know the term of the Cold War?
There were no friendly arrangements between the west and China until very recent. The hand of friendship has been extended due to the collapse of Russia and the west recognising the futility of being aggressive for the sake of being aggressive. China also opened it borders, something unthinkable before the USSR collapsed. Since the cooling of relations between the west and China, China has abused that hand of friendship in many areas. Is it any wonder that hostilities are building up again?
