That article is rather pointless as it measures highly subjective things like friendliness and compares crime stats which are derived using different approaches in different countries. So what if Japan has little to none reported crime. China has little to none reported corruption. On top of that all this is moot because it's highly dependand on what country you yourself come from. Are you black? Well, sucks to be you if you want to visit eastern Europe. Are you not Japanese? Better be prepared for some unexpected racism in Japan that will make you question what century you're living in. Do you come from a country just next door who happen to have had some history together well before you were born? That's probably the worst. Look at the comments section of that article for an entertaining explanation of why people tend to vacation on the other side of the planet rather than with their neighbours. Since the purpose of the comparison is to find nice places to go to you should compare reports based on tourist trips. Crime that happened to tourists, prices paid by tourists and service received by tourists. That kind on comparison would be a better basis for which country is best to visit.
