I'm going to keep insisting on this "identity" thing, because I think it's crucial...
Somewhere on SDF, someone posted a link to a video in which Robert Kaplan (Defense Policy Board since 2009) gives a talk at the Naval War College. His talk was about the rise of China and India and the impact of these things on American security and policy.
Robert Kaplan pointed out that China does not have a "missionary" foreign policy like the US does. Explaining this, he contrasted China also with the Soviet Union, which according to him, also had a missionary foreign policy. In other words, the Soviet Union wanted it's "model" to be extended, for everybody to emulate it, and it wanted to be the embryo of a Soviet world. The US wanted, and today still wants, everybody to follow the American "model" as well.
Robert Kaplan did not offer an explanation as to why or how a country adopts a "missionary" foreign policy. My explanation, in the case of the US, is that it has to do with American notions of "identity" (as I hope is clear from my previous post).
For the Soviet Union, this was also true. Russia, after 1917, ceased being "just" Russia, and even took on a different name, to emphasize a new identity based on it's social and political system (Soviet Socialism). It was for this reason that the Soviet Union (at least after the 30's) could not "experiment" with alternatives as China did later, because any departure from its "institutions" and ideology were seen as betrayal. Socialism had become the reason for Soviet Union's very existence.
Britain also sought to spread the British "way of life" through its Imperial enterprise, and after the French Revolution, France worked quite hard to spread its new thing. Robert Kaplan's choice of words ("missionary), reminds us of a similar phenomenon in an earlier era. For example when Spaniards conquered their land back from the Moors, they did it in the name of religion. Catholicism became part of the very definition of the country, and sure enough, Spain became a missionary power in the literal sense. Of course, the Arabic empires of the 7th, 8th and 9th centuries were such as well.
The complaint often voiced in this forum about "Western" criticism of China is that it almost invariably boils down to "China should be more like us", and to be more specific, that it should be more like the US or Britain. This, I think, is the view that Fu Yi expounds quite well in her interview.
