I’m nowhere near being an expert on languages and phonology, but I think the Ø-sounds in the Nordic languages are more or less the same. With some tiny differences on pressure, pitch, and maybe tone. Close enough to be considered the same in my opinion. It probably boils down to what would mostly be accent and dialect differences between the languages.
Preferably we’d be self-sufficient since Europe has a lot of, if not most of the rare earth minerals in various deposits. But, no wants to deal with the ugly process of extraction and processing, not to mention the upfront costs. Until someone steps up I guess we sadly have to deal with China.
