If you create multiple Apple accounts in different regions, you can switch to that regions app store in the App Store app (this doesn't have to do with your iPhone iCloud account) by logging in to the relevant account. I have a US and an Aus Apple Account, and I switch the account on App Store to get apps that are region locked.
