美国深思熟虑，终于定下对中国动手日期，时间就在18个月后

Group 1 - The U.S. has decided to impose tariffs on Chinese semiconductor products, effective 18 months from now, due to perceived harm to U.S. interests in China's pursuit of semiconductor self-sufficiency [1] - The announcement of tariffs so far in advance may be a strategic move to avoid immediate conflict while maintaining a strong stance, reflecting the U.S.'s cautious approach following recent trade tensions [3] - The tariffs will primarily target mature process chips used in critical infrastructure sectors like automotive and industrial control, allowing U.S. companies time to adjust and reduce reliance on Chinese products [5] Group 2 - China holds significant leverage with its rare earth resources, and the temporary suspension of export controls is contingent on U.S. actions, indicating a complex interdependence between the two nations [6] - The U.S. recognizes China's influence in the rare earth market, which could impact key industries such as defense and high-tech, leading to a more nuanced approach rather than broad tariffs [8] - Recent actions, such as the FCC's ban on Chinese drones, highlight the U.S.'s ongoing strategy to maintain technological dominance while also risking self-harm due to reliance on Chinese products [8]
