News Leaked TSMC Slide Shows N3E Yields Progressing Ahead of Plan

TSMC is probably looking to build fabs outside china's reach. Couldn't the Chinese navy block all ships entering and exiting Taiwan? I read they have already started doing so I think?
 
The gloomy prospect is when the TSMC's fab in Taiwan is the only one (at that time) capable to produce 3nm chips, then China annex Taiwan before TSMC have chance to implement it outside Taiwan.

China become the only country capable to produce 3nm chips. 😱
