Earlier quoted context omitted.
Norway is part of the single market (including free movement of people) and benefits from it, so, what they did is completely different from what the UK is going to do. But, most importantly, it's much much more disruptive to first join and then pull out that not joining at all.
So basicaly Norway got itself the best possible deal: all benefits of EU membership without any of the downsides (e.g. common currency or political correctnes bullshit).
I want also to point out that this would not have happened if Norway had been in the EU already in 2010 because China would not risk trade with all of the EU because of such a small incident.
