Introduction to technical challenges

In a public and surprising move that reflects a radical shift in China’s strategic and technological mindset, alongside a growing sense of confidence, Xu Zhijun, rotating chairman of Chinese telecommunications and electronics giant Huawei, formally and explicitly thanked the United States for the strict export controls it imposed on advanced semiconductors and technologies to his country. Xu stated that Washington’s harsh export controls and technological blockade have played a crucial role, serving as a powerful catalyst and direct impetus driving China to accelerate its relentless and ongoing pursuit of complete self-reliance and independence in the strategic electronic chip industry. According to various press reports and news agencies covering the event, the company chairman stated with confidence and certainty during his participation in a prominent industry and technology event held recently: Had the United States not pressured and forced our country to find alternatives and follow this complex path, we would not have been able to achieve this milestone nor done this great work in the first place; we are truly grateful to them for this motivation.

Announcement of an innovative roadmap

These bold and intriguing statements, carrying a clear tone of defiance, come just days after Huawei unveiled a highly ambitious long-term technical roadmap for developing the domestic semiconductor sector. This historic and disruptive announcement came during the company’s active participation in special sessions at the prestigious 2026 IEEE Circuits and Systems Symposium, held in Shanghai, China. During this major scientific and industrial symposium, the technology leader announced its advanced and promising plans to produce advanced electronic chips featuring transistor density entirely equivalent to the performance delivered by cutting-edge 1.4nm ultra-precision manufacturing processes by 2031. Even more surprising and impressive in this plan is the company’s insistence on achieving this massive technological leap without relying on advanced extreme ultraviolet (EUV) lithography manufacturing machines—the vital and sensitive equipment that strict Western sanctions and policies have successfully barred China from acquiring or importing in any form to curb its progress.

Tau scaling law and logical folding architecture

In an earnest effort to bypass technical obstacles, and rather than directly pursuing the traditional technological approach of physical transistor shrinkage with every generation to keep pace with global development, Huawei has devised and introduced a new engineering and design framework called the Tau scaling law. This innovative framework prioritizes minimizing the transmission time of electronic signals and data within the chips themselves over merely making transistors physically smaller. Alongside this revolutionary foundational principle, the leading Chinese company also unveiled an entirely new hardware and software architecture known as logical folding. This architecture was specifically designed and engineered with high precision to shorten internal interconnect and wire lengths, reduce latency and access time, and massively multiply transistor density without the urgent and costly need for advanced Western lithography equipment. Huawei explained that it has quietly designed and produced large commercial quantities of 381 electronic chips using early variants and prototypes of this promising approach over the past six years. The company’s next-generation smartphone chips from the Kirin family, expected to officially launch in markets in late 2026, are slated to become the first commercial products on the market to rely entirely on the logical folding architecture, targeting a massive transistor density of 238 million transistors per square millimeter—a record Huawei says can compete with and match the 3nm chip output of Taiwan’s global leader TSMC, though analysts note there are no independent evaluation benchmarks to confirm this.

Implications of Chinese progress for South Korea

These rapid and surprising Chinese technological developments have sparked alarm and alert across South Korea’s technology industry, a global pioneer. Leading financial analysts and industry experts have explicitly warned that China’s accelerated and dazzling progress in semiconductor research and development could pose a real and direct threat in the near future to the competitiveness of influential national giants such as Samsung Electronics and SK Hynix. A detailed research and analysis report published last May by the Hudson Institute indicated that South Korean tech companies with deep, vital business dependencies on Chinese consumer markets now face sharply escalating financial and commercial risks as domestic Chinese competitors rapidly and systematically bridge the technological gap. In the same vein, the esteemed Korea Herald reported that any move toward easing U.S. export controls as part of ongoing bilateral trade negotiations could ultimately deal a harsh and painful blow to Korea’s chip industry by granting and facilitating greater access for local Chinese firms to the latest advanced manufacturing tools and equipment. However, U.S. Trade Representative Jamieson Greer stated clearly in mid-May that the issue of advanced chip export controls was never a primary subject or priority during recent bilateral talks and discussions held in Beijing, sending a reassuring signal that there is no imminent intention to ease or remove those current restrictions.

Strategic shift under pressure

This firm, bold, and defiant stance adopted and announced by Huawei reflects a broader and more comprehensive dramatic shift in China’s overall national policy approach toward the vital semiconductor sector. The leading technology company is systematically reinvesting approximately 22 percent of its massive total annual revenue into engineering research and development and innovation to drive progress, even as U.S. efforts and pressure to tighten restrictions and squeeze technology escalate throughout the entirety of 2026. The U.S. Department of Commerce took escalating steps in April including banning sales of sensitive equipment to an additional, specific group of Chinese chipmakers. A core question heavily debated among scientific circles and observers remains whether the innovative Tau scaling approach can genuinely match the superior and stable performance of globally established traditional processes for manufacturing chips below 2nm—something not yet scientifically or commercially proven on a wide scale. Nevertheless, the confident comments made by the Chinese company’s chairman highlight a bitter reality that policymakers and strategic decision-makers in the United States have repeatedly warned against loudly: harsh, excessive export controls and expanded sanctions may help accelerate and catalyze the very independent technological reliance and self-sufficiency these sanctions were originally designed to prevent and nip in the bud.

FAQs

Q: Why did Huawei’s chairman send an exceptional public thank-you message to the United States?

A: He stated clearly that Washington’s strict restrictions and harsh technological ban served as a strong catalyst and primary impetus that forced China to accelerate innovation and develop its domestic chip-making capabilities without relying on Western technologies.

Q: What is the new technological development Huawei relies on to produce advanced chips?

A: Huawei announced an engineering innovation called the Tau scaling law and logical folding architecture, aimed at reducing internal signal transmission time and distance and increasing transistor density to achieve performance equivalent to 1.4nm without using banned Western machinery.

Q: How do these fast-paced Chinese technological innovations affect major Korean companies like Samsung?

A: This Chinese progress poses a direct and severe competitive threat to Korean companies as the technological gap narrows rapidly, increasing economic and commercial risks for the Korean semiconductor sector, which relies fundamentally on exporting its advanced technologies.

Q: Have these new technological claims by Huawei been independently and scientifically verified?

A: As of right now, Huawei has not provided any performance benchmarks or independent technical tests from neutral third-party evaluators to confirm the success of these bold technical claims regarding its chip performance, raising some questions among industry analysts.
