Original step to help with manufacturing of the subs came when US brokered a deal with MHI 3 years ago. The somehow magically "retired" MHI engineers appeared in Taiwan to help in development US does not have expertise to make modern non-nuclear subs. China can intimidate anyone in Europe not to sell. It was fortunate for Taiwan that Chinese pissed off Japan enough. Half a dozen of Soryu knockoffs can shut down PRC maritime trade if needed.
