Chinese Roman interaction.

[Sergey Lenkov]

Sergey,
I think you overstae the cultural/ethnic unity of China quite a bit. Chinese citizens include Mongolians, Tibetans, Turks (quite a bit), Mantsjurians, and I bet there's quite a few names that I forget here (I'm not an expert at all!), which you quietly lump on the big Chinese heap.

You understand me, I meant main ethnos - "Han", they were majority in China in time of Roman Empire, still they are majority. They are true authentic ethnos. If we could still have in Europe the Romans who still spoke Latin (of couse I don't mean us on this forum), and still preserve traditional Roman values in their mentality and everyday life - I could agree with you.
In Russia these things are more visible - though now (thanks to so-called economic reforms) all traditional nations of Russia are in the state of decline, but in Siberia still live the ethnoses ("small nations") for whom paganry and shamanism are their true authentic traditional religions since the dawn of their history. Or there is a group of Tartars - they were baptized in time of Ivan the Terrible - and while ethnically they are Tartars but they are Christans since the 16th century. And I can tell that there's no such kind of Romans in modern Europe.
Of course Chinese language, dynasties of rulers, name of the state etc. changed through the ages - but still they are Chinese.
