要求访华中国未回应，美国要加100%关税，投千亿美元搞“金穹”

Group 1 - The US-China trade war has temporarily eased following the Geneva agreement, where the US canceled 91% of tariffs and China reciprocated, leading to a rise in global stock indices and increased shipping activity [4][6] - Despite the temporary resolution, the US Trade Representative's office is considering imposing a 100% tariff on Chinese-made cranes and additional tariffs on other loading equipment, which could significantly impact US ports [6][7] - The US does not produce large cranes domestically, relying heavily on Chinese manufacturers, raising questions about the US's contradictory stance of wanting to sanction China while being dependent on its manufacturing capabilities [9] Group 2 - The issue of rare earth exports from China remains unresolved, with China controlling 60% of global rare earth mining and 90% of refining capabilities, which are critical for US high-tech products [13][15] - The US is actively seeking alternative sources for rare earths, but establishing new mines is a lengthy process, and current US technology for rare earth separation is still in the experimental stage [15][16] - The urgency for US military companies to reduce reliance on Chinese rare earths is evident, but achieving this in a short timeframe is unrealistic, suggesting a need for negotiations with China to address tariff issues and rare earth supply [16][18] Group 3 - President Trump's announcement of a $175 billion investment in the "Iron Dome" missile defense system, now referred to as "Gold Dome," reflects ongoing US concerns about perceived threats from China [20][22] - The project aims to integrate space interception technology and is positioned as a response to the challenges posed by China, although experts warn of significant technical hurdles [22][25] - The contradictory actions of the US, such as expressing willingness to engage with China while simultaneously planning tariffs and military investments, highlight the complexities of US-China relations [25]
