China-US Trade Relations: The Industrial Logic Behind Competition

The Industrial Logic Behind the Trade War: From Tariff Confrontation to Supply Chain Restructuring

Since the United States imposed tariffs on China in 2018, Sino-U.S. trade relations have evolved from a simple trade deficit dispute into a comprehensive competition involving technology, supply chains, and industrial dominance. According to the latest background analysis by the Council on Foreign Relations (CFR), despite numerous meetings between leaders of the two countries attempting to ease tensions, high tariffs, rare earth export restrictions, and technology export controls remain core sticking points. From an industrial research perspective, the essence of this struggle is the structural contradiction between China's manufacturing upgrade and the U.S. effort to maintain its technological advantage.

Changes in Export Structure: From Low-End Manufacturing to High-Value-Added Products

The most direct impact of the trade war is the significant decline in bilateral trade volume between China and the U.S. According to data from the Peterson Institute for International Economics, by the end of 2025, the total import and export volume between China and the U.S. had fallen by more than 25%. However, during the same period, China achieved a trade surplus of $1.1 trillion. This seemingly contradictory phenomenon reveals a fundamental transformation in China's export structure. China is shifting from relying on exports of low-value-added consumer goods (such as clothing and toys) to the U.S. to exporting high-end manufactured products like electric vehicles, lithium batteries, and photovoltaic products to the global market. U.S. tariffs have indeed suppressed some exports of low-end goods to the U.S., but China has opened up markets in Southeast Asia, the Middle East, and Latin America through capacity upgrades and the Belt and Road Initiative. China's record trade surplus in 2025 precisely demonstrates that its manufacturing resilience has surpassed dependence on a single market.

Supply Chain Restructuring: China+1 Strategy and Industrial Relocation

U.S. tariffs have not only changed trade flows but also accelerated the restructuring of global supply chains. Many multinational corporations have implemented a "China+1" strategy, relocating some production capacity to places like Vietnam, Mexico, and India. The CFR report points out that a large amount of trade originally conducted directly with China is now being completed indirectly through third countries, causing distortions in U.S. trade deficit figures. However, this relocation is not simply a decoupling from China. China still accounts for about 70% of global production capacity in areas such as electromechanical equipment, chemicals, and rare earth processing, and the depth and efficiency of its supply chains are difficult to replicate in the short term. For example, while the U.S. raised tariffs on Chinese electric vehicles to 100%, Chinese EV makers have turned to building factories in Europe and Southeast Asia, simultaneously driving the overseas expansion of supporting industries such as batteries and electronic controls.

Technology Decoupling and Accelerated Self-Reliance

The Biden administration has continued and expanded the export controls initiated during the Trump era, particularly targeting semiconductors, artificial intelligence, and quantum computing. This has directly spurred further strengthening of China's industrial policies: from the National Integrated Circuit Industry Investment Fund to the "New Quality Productive Forces" strategy, China is concentrating resources on overcoming bottlenecks in key equipment, materials, and industrial software. The CFR background article mentions that in 2026, both sides temporarily reduced tariffs to 30% and 10%, but the technological competition did not ease. China's self-sufficiency rate in areas such as rare earth permanent magnet materials and high-end chip packaging has increased from less than 20% in 2018 to around 40% in 2025. This model of "pressure-driven innovation" is reshaping the underlying competitiveness of China's manufacturing sector.### Long-term Trends: Parallel Development and Limited Decoupling

Most experts believe that complete economic decoupling is impractical. The combined GDP of China and the U.S. accounts for 43% of the global total, and their manufacturing output accounts for 48%, making deeply intertwined supply chains difficult to rewrite overnight. However, the long-term nature of industrial competition has been set in stone. For China, the trade war has exposed the risks of relying on external markets, driving its domestic demand expansion and industrial digitalization; for the U.S., tariffs have not brought the expected effect of reshoring manufacturing, but instead pushed up domestic inflation and consumer costs. The future game may shift to "managed competition"—setting rules through mechanisms such as a "trade committee" while maintaining isolation in key technology areas.

Overall, the Sino-U.S. trade relationship is no longer a simple matter of importing and exporting goods, but a microcosm of the two countries' competition for the commanding heights of global industries in the context of the Fourth Industrial Revolution. The upgrade path of China's manufacturing (from scale expansion to quality and efficiency) and the direction of global supply chain restructuring will be key variables affecting the world economic landscape in the next decade.
