Got more details if you look more closer, not a total Ban more like needing Permits from US government. So lobbies can be created to get the Permits which will be easy for US companies and hard for foreign companies.
Not surprising even the Chip export control isn't a total Ban, just need permits that heavily favors US companies that can still allow exports to China.
Need to Note down Ukraine is also no Match for the Russian Air force but they did a pretty good job denying Russian Air Superiority so for the US Air port winning over China:omghaha:
