Core Insights - China is tightening control over strategic resources, specifically antimony and gallium, which are critical for high-tech industries such as semiconductors, 5G, and electric vehicles [1][3][4] - Antimony is essential for stabilizing semiconductor performance, while gallium is crucial for components in 5G technology and LED screens [3][4] - China's dominance in the global supply of these materials is significant, with nearly 40% of antimony reserves and over 80% of gallium production concentrated in the country [3][4] Antimony and Gallium Importance - Antimony serves as a stabilizer in semiconductor manufacturing, enhancing the efficiency of current conduction in transistors [1][3] - Gallium is indispensable for high-frequency applications in 5G and is a key component in LED technology and satellite communications [3][4] Global Supply Dynamics - China controls over 90% of the high-purity antimony processing capacity, making it a critical player in the supply chain [3][4] - The extraction of gallium is technically challenging, as it is derived from aluminum ore processing waste, further solidifying China's position in the market [3][4] Strategic Resource Management - The scarcity of antimony and gallium, along with the difficulty in finding suitable substitutes, makes China's control over these resources even more critical compared to rare earth elements [4][6] - China's management of these resources is a response to past experiences of being "choked" by foreign restrictions on technology and materials [4][6] Long-term Vision - The current strategy aims to ensure sustainable resource management for future generations, avoiding the pitfalls of past resource exploitation [6][8] - By regulating the supply of antimony and gallium, China seeks to encourage global industries to diversify their supply chains and reduce dependency on a single source [8]

Core Viewpoint - The article discusses the recent developments in the semiconductor industry, particularly focusing on NVIDIA's H20 chip resuming exports to China and its implications for the domestic semiconductor sector and investment opportunities [1][2]. Summary by Sections Recent Developments - NVIDIA's H20 chip has resumed exports to China, with CEO Jensen Huang announcing immediate deliveries and the launch of the RTX Pro GPU for industrial digital twin scenarios [1]. - Despite strong performance in the Hang Seng Technology Index, domestic semiconductor indices like the Guozheng Chip Index showed weakness [1]. Historical Context of Semiconductor Restrictions - In October 2022, NVIDIA was prohibited from selling flagship AI chips A100 and H100, leading to the development of the A800 and H800, which had a performance reduction of about 30% but met basic needs [2]. - In October 2023, further restrictions included the A800 and H800, prompting NVIDIA to create the H20, L20, and L2 chips, with H20's performance being only 15%-30% of H100 but with increased memory [2]. - By April 2025, the H20 chip will also be banned from sales to China, with analysts estimating NVIDIA could lose $13.5 billion in revenue due to these restrictions [2]. Market Trends and Domestic Growth - The semiconductor sector has shown resilience, benefiting from the "domestic substitution" and "self-sufficiency" concepts, with IDC data indicating that China's chip market will exceed 900,000 units in the first half of 2024, with local AI chip brands accounting for 20% of the market [3]. - TrendForce forecasts a decrease in the proportion of outsourced chips in China's AI server market from 63% in 2024 to 42% in 2025, while local suppliers' share is expected to rise to 40% [3]. Future Prospects - The article emphasizes the urgency for NVIDIA regarding the H20 chip's export status, as the domestic semiconductor industry is focused on increasing the localization rate of computing chips across the supply chain [4]. - Despite current challenges, the domestic chip sector is expected to improve its market share through software and hardware advancements [5]. - The semiconductor sector is anticipated to see a potential rebound, especially with the IPOs of companies like Muxi Co. and Moore Threads, which are positioned to enhance GPU chip design capabilities [5]. Conclusion - The article concludes that selling underperforming semiconductor-themed funds is not advisable at this time, as the industry is poised for growth driven by domestic innovation and market dynamics [6].
