Late answer, but I have been looking for the same species, in the same country.
Buying Juniperus Chinesis in Sweden has become more difficult the last few years. The nurseries have a lot of pressure from pear owners not to sell Chinese Junipers due to Pear rust (Gymnosporangium). Importing junipers from Japan is not really legal AFAICS.
Chinese junipers were very popular to plant in gardens here in the 60s and 70s, maybe its possible to find some that you can dig up (with permission), since they are not in fashion anymore.
Otherwise, I think the best bet is to buy a smaller juniper from sites (located within the EU) such as
bonsai.de,
www.henhbonsai.nl
You can also ask here if someone is selling a juniper:
