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.
。这颗行星被认为是非常冷的，其表面温度与木卫二相似，大约在零下150度。然而，研究人员说，它可能有一个巨大的热铁/镍核心，地热活动非常活跃，这将有助于促进生命。维拉诺瓦大学的天体物理学家爱德华·桂南在美国天文学会第223届年会上说，核热活动可能支持地表下的“生命带”，这种现象类似于南极洲地下湖泊中的现象。我们注意到欧罗巴的表面温度与巴纳德B的相似，由于潮汐加热，欧罗巴冰的表面下可能有一个液态海洋。他还指出，如果存在水，核热活动（火山羽流、火山口等）可能在冰面下形成液态水的“生活区”。它非常像结冰的欧罗巴卫星，它是由潮汐活动而不是地热能加热的。巴纳德的恒星系统将是我们未来研究和分析的重点。

B | 巴纳德最显著的特点是，它是离太阳最近的两个恒星系统之一，而且其中有行星。这项研究的共同作者斯科特·恩格尔强调，这项研究支持开普勒先前的任务数据，这些数据可以推断行星在整个星系中非常常见，可能高达数百亿颗。同时，巴纳德恒星的年龄大约是太阳的两倍——90亿年，而太阳的年龄是46亿年。

C | 宇宙要想形成地球大小的行星需要很长的时间，甚至比太阳现在的年龄还要长。巴纳德B是地球质量的三倍，绕着红矮星巴纳德运行233天。

D | 它的轨道距离与水星绕太阳的轨道距离大致相同。

E | 当它经过巴纳德星球的雪线时，它变暗了。

F | ”这些观测将帮助我们了解大气层、表面结构和系外行星的潜在生存能力，”恩格尔说。

G | 虽然巴纳德B的表面温度约为零下150摄氏度，但科学家们仍然相信，地球冰冻表面下的液态水区域可能是生命形式的滋生地。外行星是一颗岩石行星，至少是地球的3.2倍大。

H | 巴纳德距离地球只有六光年，在天文距离上非常接近，它的亮度是太阳的0.0035倍。离太阳最近的恒星是半人马座α星，它由离地球四光年的三颗引力束缚的恒星组成。据报道，巴纳德B行星的存在是通过使用不同的陆基望远镜和天文仪器20年来发现的。其中之一是西班牙卡门尼天文台最先进的行星探测器。

I | 即使是今天最强大的望远镜也不能直接成像巴纳德B。巴纳德星的名字来自于1916年发现它的耶克斯天文台的爱德华·艾默生·巴纳德。

J | 虽然巴纳德离地球只有六光年远，但它是人类肉眼看不见的。如果你把半人马座阿尔法星系的三颗恒星作为一个单位，那么巴纳德是离地球第二近的恒星。这是一颗暗的，低质量的M4矮星，亮度只有太阳的0.0035倍。相关辐射数据表明，它的直径仅为太阳直径的20%，质量仅为太阳最近恒星的17%。大多数恒星属于M矮星，它们很弱，很难用肉眼观察，就像半人马座的邻居一样。巴纳德的明星都很老了。他们是在恒星爆炸怀孕期间出生的。当时，星际金属含量已达到目前的水平，星际金属含量仅为太阳含量的10%。它的年龄也证实了它有一个更长的旋转周期130天。随着年龄的增长，其转速逐渐减慢。
