This is what you call a proxy seller. Who knows, you might have a student from China that moved to Netherlands for studies and sells counterfeits on the side.
You cannot just base on location to judge numismatics.
Some high quality counterfeits are coming from Belarus and Poland. In fact, there is a website that boasts selling replicas and supposedly even pays taxes to the government!
