I think this is already done in some cases altough the political reliability has not yet been tested.
The EUSC will be more restricted, similar to GovCloud. Only EU citizens can access/operate it.
Specific example: an alarm fires for your service. If it’s in China, anyone on the team can go look at the logs. If it’s in GovCloud, only teammates who are American can look at the logs. In the EUSC, only Europeans can.
The sovereign cloud spec designed by the folks at France's ANSSI agency is tight.
Is this part of the spec? If not, it's as loose as a tent. And by "part of the spec" I mean "all your assets will be forcefully nationalized the second you or a parent company of yours becomes less than X% European owned", where X is well above 50.

To start with... states can and will absolutely block the sale of strategic national companies to foreign actors. But I'm sure you knew that.
