Tech restrictions against China are already backfiring.
American tech companies now have to share their cakes with non-American firms by outsourcing in order to do business with China. Further restrictions by America will kill off any business. Damages already been done permanently to American reputations as reliable suppliers and business partners.
Hawkish Americans say that stopping sales of advanced tech to China will slow China advancement. Yes it will only slow down, not stopping. China still has alternative suppliers. Sure China will suffer some pain now, however within five years, China should be able to achieve parity with the world's best.
Eventually non-American firms will wean themselves off American tech to remain in the global supply chain in high technology. This is not in America's interest. It will severely curtail their competitiveness. Just my opinion.
