the ranking seems very wrong to me and checking their website through the cointelegraph link you posted below, it looks to me that they are basically saying Switzerland is #1 because it has ethereum foundation in it. and as for China as the worst, that is obviously wrong. there are at least 3 countries that have banned bitcoin and other cryptocurrencies and 1 (Bangladesh if i am not mistaken) which will imprison anyone who uses them. such countries are a lot more unfriendly than China that sees bitcoin as a legal thing!!!
Yep, I do find this ranking a bit uninformed too. Mexico, for instance, is taking a path towards acceptation, but it appears on the "negative" list...
This is not informed enough to answer the OP question, I'm afraid, but, given this is just an opinion, I think the aims about crypto regulations are not going to influence international relationships in any way, at least, as well as the crypto use is not mainstream.
We are into crypto, but we are still few. As well as more people begin to use it, I think there are going to emerge some international agreements.
In the other hand, we have the exchanges' problems. Some countries, like Russia or the US are starting to ask them for personal users data. It, of course, can make people moving into another one and use other services from China, for instance. But, what happens if, for example, the US government ask for this exchange to share their data for some reason and they don't have any, can it be an international problem? Some Us exchanges are starting to ask their users for an official ID, along with the place of residence, the phone number and also a personal photo of their faces, recently taken. Indeed, other ones also ask the user to download a facial recognition program, so they can scan their face. Of course, it is making users moving into another exchange, but how is going to be the US and Russian attitude towards those exchanges that don't fulfill the requirements they find to be obligatory?
