This is the push that Huawei needed to reduce their reliance on US businesses in their products down to zero, and I suspect other foreign telecoms manufacturers will be watching before considering whether they could make the same leap.
The reviews of the new Huawei Mate 30 Pro have praised the hardware, however the lack of Google Play services is the killer if you're not in China. Again, if Huawei can figure out how to get a high percentage of play store apps to load (perhaps by curating an alternative app store), then other phone makers may follow suit.
Trump's plan to help US businesses only works while the non-US companies haven't developed a better solution.
