第二项措施是针对大型飞机发动机的管控。对此，我们的影响相对较小，因为我们早已为此做好了相关 准备。虽然我们选择使用国外发动机来满足欧盟和美国的适航标准，但实际上，我们的自产发动机已经 在运20上进行了良好测试，而进口发动机的库存也足够再用至少两年，因此这项限制并不会造成根本性 的影响。 第一，针对中国留学生的措施。准备对赴美留学生的签证进行取消，这将对已经在美国的学子们造成很 大的影响。毕竟他们在美国的学习和生活投入了大量的金钱和精力，转而去其他知名高校的选择，虽然 有人提到香港的两所世界排名前百的大学愿意接纳他们，但终究也会面临适应新环境的挑战。 然而，从长远来看，这或许并非坏事，毕竟绝大多数赴美留学的学生都是极具才华的人才。根据统计数 据，许多留学生毕业后选择留在美国，为美国贡献他们的智慧，而现在这些人才有可能会为国内的发展 贡献力量。 然而，半导体设计领域的禁令则显得尤为棘手。若这一禁令得到严格执行，将不仅影响先进制程的研 发，甚至连传统制程芯片的优化设计也会遭殃。在这种情况下，一些设计公司不得不转向开源架构，虽 然这并非最佳解决方案，但也是无奈之举。近期，有消息称华为开始着手研发EDA软件，若华为能够 ...

1. Report Industry Investment Rating No relevant content provided. 2. Core Viewpoints of the Report - Last week, the situation of the trade war was uncertain, causing the bond market to fluctuate. With a loose funding environment and the overnight interest rate dropping back to 1.4%, ultra-long bonds were slightly pressured, showing a V-shaped trend throughout the week. The trading activity of ultra-long bonds increased slightly, and both the term spread and the variety spread widened [1][11]. - For the 30-year treasury bond, as of May 30, the spread between the 30-year and 10-year treasury bonds was 23BP, at a historically low level. Considering domestic economic data, the economy in April still showed resilience. The estimated year-on-year GDP growth rate in April was about 4.1%, a 0.8% decline from March but still higher than the annual economic growth target. In terms of inflation, the CPI in April was -0.1% and the PPI was -2.7%, indicating obvious deflation risks. With the recent easing of Sino-US trade frictions and the dissipation of investors' pessimistic expectations, the short-term focus will shift to the domestic economic data of the second quarter. It is expected that as the policy support effect weakens, the bond yield is more likely to decline. However, the current term spread of the 30-year treasury bond is still low, providing limited protection [2][12]. - For the 20-year CDB bond, as of May 30, the spread between the 20-year CDB bond and the 20-year treasury bond was 2BP, at a historically extremely low level. The domestic economic situation in April was similar to that of the 30-year treasury bond. It is also expected that the bond yield will decline as the policy support effect weakens. However, the current variety spread of the 20-year CDB bond is still low, providing limited protection [3][13]. 3.

Group 1 - The core viewpoint of the article highlights a significant shift in Trump's attitude towards China following the consensus on tax reductions, indicating a growing urgency to engage with China despite previous aggressive stances [1][3]. - Trump's previous confidence in China's willingness to negotiate has turned into a desperate need for dialogue, as he seeks to visit Beijing and has expressed a desire for direct talks [1][3]. - The article suggests that the pressure on Trump has increased due to the adverse effects of the trade war on the U.S. economy, leading him to seek a meeting with China to secure favorable conditions before losing leverage [3][5]. Group 2 - The article notes that China has reduced its holdings of U.S. Treasury bonds, selling $18.9 billion in March, which has resulted in China losing its position as the second-largest holder of U.S. debt, now held by the United Kingdom [4][5]. - The shift in debt ownership from China to the UK raises concerns about the stability of the U.S. economy, as both Japan and the UK are struggling to manage their roles in holding U.S. debt [5][6]. - Trump's contradictory approach towards China is evident, as he seeks assistance while simultaneously attempting to contain China's growth, reflecting a divided strategy in U.S.-China relations [7][8].

Group 1: Trade Negotiations - Recent US-China trade negotiations have made some progress, with both sides agreeing to revert tariffs to pre-Trump's "reciprocal tariff" policy levels [1] - However, there are indications that Trump may change his stance and propose new tariffs, which aligns with his historically unpredictable behavior [1][3] - China has been preparing for potential changes in negotiations, given the long-standing nature of US-China trade tensions that began during Trump's first term [1][3] Group 2: Rare Earth Resources - Rare earth resources have become a significant topic in international trade, particularly in the context of US-China relations [5] - These resources are scarce and non-renewable, widely used in advanced technology, and have been dubbed "the mother of new materials" and "industrial vitamins" [6] - Rare earth elements are essential in various applications, including enhancing the strength and lifespan of steel, which is crucial in military applications [8] Group 3: China's Dominance in Rare Earths - China holds the world's largest rare earth reserves, accounting for approximately 25% of global reserves, and produces about 80% of the world's rare earth products [11][12] - The global rare earth market is largely dominated by China, with around 70% of its exports going overseas, indicating a high level of dependency from other countries [12] - China's southern regions contain over 70% of the world's heavy rare earth resources, providing it with a strategic advantage [12] Group 4: US Dependency and Response - The US relies heavily on China for rare earth compounds and metals, with over 70% sourced from China in recent years [14] - The US has not yet mastered the technology for separating heavy rare earths, which is critical for its defense industry [14][16] - In response to this dependency, the Trump administration initiated a domestic rare earth supply chain restructuring plan, but this requires significant investment and time [17][19] Group 5: Strategic Implications - Rare earth resources have become a key bargaining chip for China in trade negotiations, with China showing no willingness to make concessions [21] - China's strong position in rare earth resources gives it confidence in dealing with the unpredictable nature of US trade policies [21]
