I am fascinated with the growth of Ancient China, how they grew to be a rich power with the most advanced technologies. However by they later were conquered by the Mongols, the Manchus and had numerous defeats to the Colonial powers. Was the way they looked power and geopolitics different from lets say the rest of the world. China historically have not been an expansionary power, and may not have seen immediate threats. China have also a very centeralized view of power, which may be good for effeciency but that breeds corruption and power struggle. China has also been isolated to a spot where they are very population dense and have fights over geoeconomic power.
