I know this is taking the thread back to first principles but...
1) China may or may not become the largest economy (or close) in the world over the next 30 years
2) There is nothing the rest of the world can do about this except through war (undesirable if not unwinnable) or economic sanctions (undesirable and again 'unwinnable' as a lot of the world would not go along with it for various reasons)
3) The only thing the US and Europe can reasonable hope to do is slow China's rise by holding back technology (the Europeans may not even want to do this for various reasons)
Therefore:
Holding back China's rise
Advantages
Maintaining US military dominance of the region for the time being will hopefully mean that the Taiwan question is resolved peacefully.
Disavantages
Set back Western-Chinese relations
Aiding China
Advantages
Signal the China that the west (or Europeans at least) wish to deal with the Chinese as equals, promoting harmony
Possibly set up the Europeans (in the case of the EU selling arms to China) as honest brokers in Chinese-US relations - someone reasonably powerful on the western side of the divide that the Chinese can feel are genuinely unbiased
Disadvantages
China becomes more powerful and decides it can invade Tiawan and win
China uses technology to challenge US/Western military/economic dominance of the world (though some might say a balance like this is a positive
