> Moles are not unique to China, it just happens that China currently happens to be the enemy.
The special position of China goes dramatically beyond that. I'm not sure you could downplay China's position more than what you just did. I'd almost confuse them for being Cuba by that description.
For all but a few countries, stealing data on how to build the next great airplane, does not enable them to actually build it.
The unique position of China is the combination of: vast resources and a very determined, centrally orchestrated, national will to pursue hegemony (now almost universally culturally regarded as their natural right).
Pretending a mole from China is similar to a mole from most any other nation, is pretty absurd. No other nation other than the US has the capabilities that China now possesses.
They have: extraordinary national wealth ($50x trillion in household wealth); extraordinary annual economic output; rather openly flaunted mercantilism; global leading manufacturing capabilities spanning nearly anything as needed and supply networks to match; a strong cohesive nationalism, supported by both the people (culture) and the leadership; very large, very potent tech capabilities, spanning everything from software to hardware, unrivaled by any nation other than the US; military spending that pretty well matches the US when you adjust for either PPP or just merely adjust for the difference in salaries; extremely large land & water territory, and all the benefits that go with it; nuclear weapons and military technology that by the day is getting close to parity with other elite militaries; an authoritarian system that is willing to entirely disregard human rights whenever it suits their national purpose at the time and a culture that heavily tolerates it; the ability to rapidly pursue epic scale, unmatched (eg Three Gorges) national construction and or engineering challenges at the snap of a CPC finger; and 18% of the world's population, for practical purposes an endless supply of relatively cheap labor of all types.
Show me a bunch of other nations like that. In all of human history you can count on one hand the number of nations even remotely comparable to where China is now at, their general position and capability vs peers in the world order. And they're not quite done rising in power yet.
