So like in the rest of the world... And for some reason we're not seeing any concrete steps being taken to allow for better international cooperation between police forces and judiciaries of various countries to make it easier to catch scammers and fraudsters. The best EU and the USA can come up with are onerous regulations.
There are some attempts, but the thing is the people in these law enforcement bodies have problems with understanding the nature of blockchain and cryptocurrencies - their main solution is to try to make them work in the same way as bank wire transfers and use already available tools.
But this is a true challenge - you can cut off eg. whole Iran from the international banking system due to the UN sanctions, but how to do the same in case of cryptocurrency wallets? Especially as you yourself can create a cold wallet?
