I agree with TylerDurden, but just to elaborate a little on the politics of the matter.
One, most European countries are vibrant democracies. Thus, nimby-ists, sentimentalists, incumbent property owners, environmentalists, and the like have greater opportunity to veto any new developments. So, like TylerDurden says, these guys don't really have much of a say.
Two, Europe has a much greater share of nimby-ists, sentimentalists, incumbent property owners, environmentalists, and the like.
So for example, even if China were a vibrant democracy, there are far fewer sentimentalists who would protest against the construction of a skyscraper next to say the Forbidden Palace. Also, for obvious reasons, there are also far fewer incumbent property owners who have an interest in blocking the increase in the supply of office/housing space.
Three, even compared to the US, Europe has a much stronger anti-capitalist/sentimentalist spirit. And in Asia the pro-capitalist/pragmatist spirit is probably even stronger than in the US. If a tall building means everyone will be richer, people in Asia will support it, while Europeans will think of all sorts of reasons to oppose it.
Based on the above arguments, it is perhaps not surprising that the European city with the most skyscrapers is Moscow (31). (Wikipedia) Second is Istanbul (28).
A distant third is Paris (18) and fourth is London (15) where property prices are ridiculously high and, if run by Chinese/Singaporean technocrats or HK free-marketeers, would have far more skyscrapers.
