How to break a new comer on stage

If Biden continues Trump's blockade policy in the next year or so, he will also sell high-tech products to Europe, Japan and Japan, and cultivate competitive companies (one is to ensure that their own high-end products have market profits, and the second is to stimulate them.) what will they do? The investment in high-tech industries will be at a high-tech level. If not, it will actively widen the gap between China and the world's cutting-edge technologies (high-tech companies in cultivating Africa can force China to invest heavily). A year later, according to China's investment situation, it will gradually open up sales of medium and high-tech products. Will Chinese enterprises switch to large-scale procurement? It is likely that a large number of purchases will be made, and not purchasing will widen the gap between its own products and cutting-edge technology products (and the investment in hardware has not yet made a breakthrough in product technology, and the huge amount of investment has already been spent). Enterprises have interests to consider. If they want to keep the market, they must have products that can be obtained. The market does not believe in bitter drama. Some people buy in large quantities. The United States only needs to do research and development and production of high-end core products If the technology is in their own hands, OEM has the chip products of TSMC. Whether the investment will be done or not (low end profits are already small), and neither do nor profit (and throw in the water), and before trump will be bundled up by trump, the US will be tied up (Cai Dumei is biased towards Taiwan Alliance, and the fruit will be bundled with Taiwan and achieve further conspiracy. If it is the predecessors who set up the stage, the later generations sing opera! In this way, will Biden maintain the leading technology in the United States and then win a good reputation in the world (market globalization)?
