Group 1 - The core viewpoint is that Trump's decision to impose an additional 100% tariff on all Chinese goods reflects emotional responses and indicates a lack of effective strategies in the U.S.-China trade conflict [1] - The U.S. has limited options to counter China's recent export controls on rare earths, which complicates U.S. efforts to rebuild its rare earth supply chain [1][3] - The U.S. has historically engaged in trade bullying without facing significant pushback, but China's strong countermeasures have disrupted the U.S.'s previous advantages [3] Group 2 - The U.S. continues to rely on traditional methods to exert pressure on China, particularly in high-tech industries and geopolitical issues like Taiwan, despite the ineffectiveness of these strategies [4] - Recent actions, such as Poland halting the operation of the China-Europe Railway, suggest U.S. influence in attempts to disrupt China's trade routes [4] - The U.S. lacks confidence in its ability to militarily confront China in the Pacific, and its trade tactics have lost their effectiveness [5] Group 3 - As military options become less viable, the U.S. may need to reassess its approach to China and consider a more rational policy focused on peaceful coexistence [7]
