最后5天，中国又一邻国跟美国签了，特朗普连退3步，中方收到通报

Group 1 - Cambodia successfully signed a trade agreement with the United States just before the expiration of Trump's tariff grace period, marking a significant economic move for the small nation [1][5] - The agreement is crucial for Cambodia, as the U.S. market accounts for 40% of its total exports, primarily in garments and footwear, making the potential 49% tariff pressure unbearable [5][8] - The deal requires Cambodia to enhance scrutiny over the origin of exported goods, which poses a challenge since 65% of its garment materials come from China, effectively limiting its supply chain options [7][8] Group 2 - On the same day, the Trump administration made concessions to China by lifting restrictions on exports of key technologies, including aircraft engines and chip design software, indicating a complex negotiation strategy [10][11] - The U.S. concessions appear to be a response to domestic pressures from energy and technology sectors, aiming to stabilize its own economic interests while managing trade relations with China [11][15] - The new tariff notifications sent to ten countries, with rates ranging from 10% to 70%, signal a potential disruption in the global trade system, particularly affecting Southeast Asian nations [12][13] Group 3 - The European Union is preparing retaliatory measures against U.S. goods, which could lead to significant costs for European automotive manufacturers if negotiations fail [13] - China's response includes extending anti-dumping measures against the EU and accelerating the development of its domestic aircraft engine, indicating a strategic pivot in its trade approach [13][15] - The overall trade landscape is characterized by a lack of clear winners, as the intertwined global supply chains make it difficult for any party to emerge unscathed from the ongoing trade tensions [17]
