The US is supposed to be an ally of many, if not the majority, of UN members. China is not. So from, say a Spanish POV, China, not regarded as an ally, spying is expected, but an ally industrially spying is more difficult to accept. In fact, something like this may well destabilize the UN. How can such an institution be trusted if its major player and funder is using it as its own conduit for spying? Yeah "we" all "knew", not now we really do know. Its fact.
What this proves is that the US is an ally of no one. The US has abused it's self entitled presumed position of trust. Now when there is some international jolly, or what ever, US requests for insane amounts of comic book, sunglasses wearing, gun toting SS to be allowed free armed reign may well be met with a lot more skepticism. The usual suspects will continue to suck up (the UK for example has no where else to turn to, given its attitude to the EU), but over all I see a lot more difficulty for the US behind the scenes and diplomatically.
In short, there is a huge difference between an enemy spying and a so called ally.
