Semiconductor foundry is the current bottle neck of China. The agreement with U.S is lethal for mainland chip manufactures and will potentially grind the electronics market down to a halt. 4 of top 10 pure-play companies in the world is in Taiwan. IMO this move too obvious and weak to attract talents from these companies. Few people would join the 'chase up to the frontier of technical know-how' just because of better salary packages. It's possibly a 'worst case' scenario type of planning.
