You're going to very hard pressed to build a phone outside of Asia, and even more so without Asian components. Fabrication of the case and battery are doable outside of Asia, although to get a phone shaped battery, you might need to roll your own. I know of no major manufacturer outside of Asia. Case can be cnc'd just about anywhere. Board is going to be difficult, but easier. AllPCB can probably take care of the high layer count board, but it's not going to be cheap. Screens are going to be a bigger issue than battery. I know of no modern phone sized screen manufacturers outside of asia that could make a 1080P screen in bulk. That's not something that would be easy to roll yourself either. Chips are going to be, by far, the most difficult part. If you're willing to call the Philippines part of Oceania, it's a bit easier, but not much. Even if you can get a CPU, ram and flash storage chips made outside Asia (big if), all your small passives are made in China and basically nowhere else. This is ignoring assembly, cameras, coatings, etc. Basically, any phone you buy is going to be majority Asian manufactured. Even if you wanted to make a phone domestically, I doubt you could make anything that competes with Chinese products. I'm not sure what the wording on the ban is, so this might not be as drastic as I think.
