In the strategy of ‘small yard, high fence,’ the U.S. appears to be striving to maintain its technological hegemony, but inadvertently promotes China’s independent innovation. The success of DeepSeek is not just a victory of algorithms, but a silent mockery of the U.S. technological hegemons. The rise of Huawei is a demonstration of the resilience of Chinese technology enterprises. Although the U.S. tries to contain China through technological blockade, the result is ‘the opposite of the intention,’ not only failing to stop China’s progress, but also accelerating China’s independent research and development. Does this mean that the so-called ‘American exceptionalism’ should also ‘retire’?
