I don't see how: China only started in 1949. The USSR is older than that, while the USSR's zombie reincarnation is only about 30 years old. If you're talking about historical China, then you might as well talk about Genghis Khan or the founding of the city of St. Petersburg or whatever; it's kinda pointless because modern nation-states don't resemble those ancient societies at all.

it's not pointless, it's history. Genghis Khan and St Petersburg are good examples.

No, it IS pointless. The society that existed in Khan's day doesn't resemble modern society in any way. So by your logic, the United States is actually tens of thousands of years old, because it started when the Native Americans crossed the land bridge from Asia, and various countries in sub-saharan Africa are several millions of years old because that's when modern humans first evolved there.
