中美经贸“停战”仅一天，美国为何又启301调查？

Group 1 - The core point of the meeting between the US and China leaders in Busan is the agreement on economic and trade cooperation, including the US decision to suspend the 301 investigation into China's maritime, logistics, and shipbuilding industries for one year [1][3][5] - The US will also cancel the 10% "fentanyl tariff" on Chinese goods and continue to suspend the 24% "reciprocal tariff" for one year, which were originally set to take effect on November 10 [3][5] - Despite these concessions, the US Trade Representative's Office initiated a new 301 investigation to assess China's compliance with the "Phase One Trade Agreement," indicating ongoing scrutiny of China's trade practices [5][6] Group 2 - The "Phase One Trade Agreement" signed in December 2019 aimed to halt the trade war, with China committing to purchase an additional $200 billion of US goods and services over two years, but actual purchases only reached approximately $1200 billion, falling short of the target [5][6] - The US perceives slow progress in China's structural reforms regarding intellectual property protection and technology transfer, maintaining pressure on China despite verbal commitments to cooperation [5][6] - The US's dual strategy of public cooperation and private pressure reflects its negotiation tactics, with the 301 investigation serving as leverage in future negotiations [6][8]
