I agree that export restrictions would potentially help the advantage in the AI race to some extent, however, the primary factor that leads to the tech advancement and China's dominance in manufacturing is not where the US sells to, but where the US buys from. I would say the best resource to advance an industry is not IP thefting or government subsidies but the tech leaders' purchase orders (and customers' specifications and requirements learned from those orders). For instance, AAPL has contributed to the progress of the component supply chain and then the emergence of a bunch of China phone companies. Later TSLA did the same for the Lithium-ion batteries companies and the EV industry in China.
