When you buy uranium (or anything else) it becomes yours. It doesn't matter where it came from. Similarly if you are a uranium mining company that digs up and/or refines it.
You call that thing you're typing on "your" computer, don't you? That much of it came from Taiwan or PRC is irrelevant.
What was actually sold was a company that had mines all over the world, and several large scale refineries in the United States.
I'm familiar with the details - it was a Canadian company listed on the Toronto TSX put together as a grand package by a consortium of Anglo-Australian miners over the course of several years.
The meat in the package was the (contentious) leases to extremely high grade reserves in Russian adjacent territory, the contention came about due to a bit of "Brooklyn Bridge" style overselling by ministers from the former USSR country, the Clintons were called upon to add gravitas to the preferred ownership path in order to seal a deal that had as one result Russian miners RosAtom supplying the US with uranium from the former USSR grounds via the Uranium One leases.
The refineries in the US were very much the paperclips in an office table drawer that happened to go along with the company sale, in economic terms they weren't of any great interest, save to the pundits on the US right who spun mad tales about the deal.
