nope, the tech trade war has always been there since the country was founded in 1949, for tech such as semi conductors, machine tools, industrial software, etc. US just escalated it by placing more restrictions and targeted large swathe of the CN economy. But because of the decade of sanctions, the R&D industrial base for many of these tech is there, just very small, no market maturity, but there is human resources, there is IP and know how. Sanctions just give these actors a chance to really improve.
