Huawei — key-event: Placed on U.S. Entity List, restricting access to U.S. technology

NoteThe source confirms that Huawei faced U.S. restrictions and sanctions, but does not explicitly confirm the specific May 2019 Entity List placement or the detailed restrictions mentioned in the claim (TSMC, Google services, semiconductor tools). The source discusses January 2018 Iran sanctions restrictions and 2020 Honor brand sale under sanctions, but the specific May 2019 Entity List event and its particular consequences are not addressed in the provided excerpt. The claim's core assertion about restrictions is partially supported by the general sanctions context, but the specific mechanism (Entity List as of May 2019) and detailed consequences are not verified by this source text.
