The real map of China

Every time I look at a map of the People`s Republic of China I wonder how much of that land would remain in China if we left only what is truly Chinese. In the same way after the collapse of the Soviet Union we could see how many countries the Soviets occupied and how many they lost. Maybe one day the People’s Republic of China will also collapse and then it would become a relatively small country, more or less of the size of France.
