This topic keeps popping up here where there is a "concern over the Danish/US influence stopping the Kvanefejld project from continuing due to "strategic purposes"
The debate is not applicable here. I hope the below insights direct from the actual authorities puts a stop to these concerns.

Please remember. Shenghe were not rejected from direct investment into a REE mine (Mountain Pass) upon US own home soil for "strategic purposes"
So why would anyone think the US would then suddenly object to Shenghe investing into a REE mine in anywhere else in the world for "strategic purposes"?

The Danish/US conern only is when the Chinese are investing directly into installations offering other purposes eg airports, ports etc as they offer the potential for for military/"strategic use".

Danish Defence Minister Claus Hjort Fredericksen said in a June 4 interview in his Copenhagen office.“Of course, we welcome cooperation with China in the commercial field. As long as it has commercial purpose, we are not opposed to that. That is a normal way to expand world trade,” Fredericksen added. He spoke with reporters during a visit to Denmark arranged by the Atlantic Council. Defense News accepted travel and accommodations for the trip.“But we are very careful looking at the issues if these installations may have other purposes, and that is what is causing trouble.”

"Mining raises local concerns, but no US pushback as yet
Unlike the airport project, the US has not pushed back against Chinese participation in mining in Greenland, probably because, unlike an airport, mining is not of direct strategic concern to the US.Moreover, despite the name, REEs are not really that rare but difficult to mine and commercialize. Chinese companies have managed both the technological and the commercial aspects but, as some observers argue, should China dramatically raise REE prices or restrict their availability, production could be diversified to compensate. For now, at least, investing in mining represents an opportunity to attract Chinese investment in infrastructure without alienating the US."
