Months-long American export license delays are costing the US billions in exports and eroding American market share globally, the US-China Business Council (USCBC) said in a flash survey released on Tuesday.
The survey noted that poorly calibrated US export controls weaken American companies in China, ceding market share to foreign competitors while reducing the profits available for research and development (R&D).
Designed originally to safeguard national security and serve legitimate foreign policy interests, the US export licensing system has become increasingly politicized, gradually turning into a political tool that obstructs normal economic and trade exchanges. The USCBC survey serves as a stark reminder of how such overreach has backfired on American companies.
In recent years, US politicians have clung to the misplaced belief that restricting exports of advanced goods and core technologies would slow the upgrading of China's tech industry and secure America's technological supremacy. Yet, they overestimated their leverage, while grossly underestimating the developmental resilience that China has built over decades of growth.
Today's China is no longer a passive follower or technology importer. Instead, it has grown into a robust innovation powerhouse with complete industrial chains and strong endogenous driving forces in numerous key technological sectors. Rather than stifling China's technological progress, America's escalating containment measures have only forced China to accelerate industrial upgrading and supply chain optimization.
In the meantime, while US politicians have been indulging in the illusion of building a "tech wall" through licensing restrictions, the self-inflicted damage to the US has grown increasingly impossible to ignore. Reuters reported in August 2025 that thousands of license applications by US companies to export goods and technology around the globe, including to China, were in limbo because turmoil at the agency in charge of approving them had left it nearly paralyzed.
The USCBC survey also listed license delays as the most common challenge identified by 95 percent of companies. For items bound for Chinese customers, two-thirds of companies have had licenses pending for at least three months, exceeding the US Commerce Department's statutory requirements to process applications within 90 days, and 31 percent have had licenses pending for one to two years.
As a result, American tech companies can only watch helplessly as orders that once belonged to them flow to suppliers in other countries. These licensing delays not only impose administrative costs far exceeding expectations, but also severely disrupt normal cross‑border commerce. From semiconductor components to high‑end industrial materials, and from aerospace ancillary products to cutting‑edge research instruments, countless routine trade transactions have been artificially severed. The market advantages that US firms took years to forge is being eroded by the very policies meant to protect them.
From a deeper economic perspective, the export licensing system is particularly lethal to America's innovation ecosystem. Usually, companies allocate a significant portion of their revenue to R&D and technological innovation. However, if the products resulting from these investments cannot be sold in a major market, investment returns will be affected, and the incentive for companies to continue investing in innovation will be undermined. As underscored by the USCBC survey, the export licensing regime diminishes America's ability to innovate and undermines US economic security.
In trying to contain China's industrial rise, the US has ended up undermining its own interests, laying bare the fundamental divide between two development paths. On one hand, the US attempts to fragment global industrial chains through administrative intervention, trade barriers and technological "decoupling" to sustain its dominant position. Yet, such obstructive practices only undermine the competitiveness of domestic industries and weaken America's own innovative vitality.
On the other side, China adheres to high-standard opening-up and win-win cooperation. By continuously opening its vast domestic market and providing foreign companies with a stable business environment, China has built a mutually beneficial global industrial collaboration network. China understands that genuine competitiveness comes from sustained independent innovation, sophisticated industrial supporting systems and market vitality. Precisely because China has chosen to expand openness and deepen cooperation, it has demonstrated remarkable resilience in the face of external containment and constructed a globally integrated supply network.
。 钢材如何做到强度过硬，还能抵御海水腐蚀？在河北唐山的钢铁实验室，记者找到了答案。钢材加工过程中会产生易导致材料脆化的碳化物，科研人员通过调控钢材原子结构，将碳化物有效包裹。 研究人员给记者算了一笔账，一台海上风电机要用钢数百吨，换上这种高性能钢，钢板可以做得更薄，合金用量也大幅减少。 如今，不只在海上，我国已经搭建起覆盖深海装备、舰船制造、航空航天等多场景的高端钢材自主研发量产体系，从材料配方、轧制工艺到批量生产实现全链条自主可控。 眼前这款是我国自主研发的“蝉翼钢”，厚度仅有0.07毫米，具备高强度、高延展性，达到全球精制钢顶级水平。 目前，这款钢材已广泛应用在集成电路基板、5G基站信号接收器等多个领域。而在航空航天领域，新研发的低膨胀特种钢材已经投入大飞机复合材料成型模具生产，数据显示，今年以来，已有7种高端钢材实现全新突破，面向新能源汽车、人形机器人、储能装备等新兴赛道，多款专用电工钢、高强结构钢实现批量下线，为新兴装备核心部件提供材料保障。 目前，我国已有3家钢铁企业入选全球“灯塔工厂”，累计培育36家卓越级钢铁智能工厂、2家领航级智能工厂。
