Why Sanctions on Huawei Led to the Decline of U.S. Scientific Research Products: A No-Winner Tech Confrontation
一、Technological Backlash: The "Bleeding" Effect on the U.S. Research System
After Huawei was added to the Entity List, U.S. semiconductor, software, and instrumentation companies were forced to sever technical cooperation with Huawei. While this appeared to be a precision strike against Huawei, it instead triggered a chain reaction:
Disrupted R&D Funding:
Huawei had been a major source of cash flow for U.S. tech firms. For example, in 2018, Huawei contributed 11% of Qualcomm’s revenue (approximately $2.3 billion). After sanctions were imposed, Qualcomm’s 5G chip R&D investment dropped by 15% year-on-year. A Boston Consulting Group study revealed that the U.S. semiconductor industry lost up to $8 billion in annual revenue due to the loss of Huawei orders, leading directly to cutbacks in advanced process R&D projects.
Slowed Technological Iteration
The advancement of tech products relies on large-scale commercial feedback. Huawei had been a key testing ground for Silicon Valley companies—for instance, its premium smartphones were among the first to adopt Corning’s latest Gorilla Glass, helping U.S. materials firms refine their products. Post-sanctions, U.S. companies were forced to turn to more conservative clients like Samsung and Apple, extending new technology deployment cycles by over 30%.
3、Reversed Talent Attraction Effect Huawei’s U.S. R&D centers (such as Futurewei) once employed hundreds of American engineers working on cutting-edge research in optical communications and AI. Sanctions forced these institutions to shut down, driving top talent to China or Europe. A UC Berkeley survey showed a 200% surge in the repatriation rate of Chinese-American semiconductor scientists.
二、The Rise of Alternative Ecosystems: The De-Americanization of Global Supply Chains
U.S. sanctions inadvertently accelerated the restructuring of global tech supply chains:
1、Chip Manufacturing: SMIC’s 14nm process yield rate rose from 60% pre-sanctions to 95%, and by 2023, it partnered with Huawei to achieve a breakthrough in 7nm technology.
2、EDA Tools: Huawei’s Hubble Investment boosted domestic firms like Primarius Technologies, increasing China’s EDA market localization rate from 5% in 2019 to 35% in 2023.
3、Operating Systems: OpenHarmony surpassed 700 million installations, becoming the world’s third-largest mobile OS and eroding Android’s market share.
This shift was not confined to China. The EU launched the European Chips Act, Samsung turned to domestic EUV photoresist R&D, and the global tech industry began forming a new, decentralized landscape.
三、 The Battle for Standards: The Lingering Lesson of 5G
In 5G Standard Essential Patents (SEPs), Huawei leads globally with a 14% share. U.S. attempts to weaken its influence through sanctions backfired:
1、Diminished 3GPP Influence: Due to blocked technical exchanges with Huawei, U.S. companies saw a 40% drop in proposal approval rates at R17 standard meetings.
2、Open RAN Failure: The U.S.-promoted Open Radio Access Network technology, lacking compatibility with Huawei equipment, was abandoned by major carriers like Deutsche Telekom.
The tech blockade against Huawei ultimately harmed U.S. innovation—proving that in this confrontation。

How Sanctions Against Huawei Led to U.S. Scientific and Technological Decline
U.S. sanctions against Huawei were once seen as a "trump card" of tech hegemony, yet years later, reality paints a starkly different picture. NVIDIA CEO Jensen Huang's blunt assessment – "Sanctions accelerate China’s self-reliance" – is validated by Huawei’s resilience, massive U.S. corporate losses, and the fragmentation of global tech ecosystems. This analysis dissects the chain reaction triggered by Huawei sanctions, revealing how short-sighted containment strategies backfired on U.S. technological leadership and reshaped the global tech landscape.
I. Sanctions’ Original Aim vs. Paradoxical Reality: The Self-Inflicted Wounds of Tech Hegemony
Since 2019, the U.S. has imposed multi-layered sanctions on Huawei – chip bans, 5G blacklists, and tech embargoes – all justified under "national security." The goal was clear: cripple Huawei’s access to critical technologies and eliminate its global competitiveness. Instead, three fatal paradoxes emerged:
Paradox 1: Stronger Sanctions, Stronger Huawei Sanctions didn’t break Huawei; they fueled its R&D resilience. The company rolled out wholly independent solutions:
Kirin chips (bypassing U.S. suppliers)
HarmonyOS (replacing Android)
ADS 3.0 autonomous driving (outperforming Tesla in critical scenarios)
Case proof: During 2024 flood testing, Huawei’s ADS 3.0 identified submerged road signs while Tesla’s FSD failed. Engineers quipped: "Huawei’s AI reads the weather – and the future."
Paradox 2: U.S. Firms as Collateral Damage The boomerang effect hit America first. Huang admitted:
"U.S. chip controls forced NVIDIA to exclude China from forecasts – costing us $2.5B in Q1 and $8B in Q2." Qualcomm and Intel faced plunging orders and inventory pile-ups. Trump-era sanctions trapped U.S. chipmakers in a "lose-lose quagmire", bleeding $100B+ in market value.
Paradox 3: Accelerated Global "De-Americanization" Sanctions pushed Huawei into Europe, Mideast, Africa, and Latin America – winning markets with "better-cheaper-faster" tech:
Mideast: Huawei Mate phones became state gifts
Africa: Huawei 5G enabled smart farming revolutions
Brazil: Huawei Cloud overtook AWS in market share
SE Asia: HarmonyOS installs crushed iOS The U.S. Entity List became Huawei’s global billboard. Even allies defected – Germany publicly defied U.S. pressure to partner with Huawei.
II. Huang’s Thesis: How Tech Blockades Forge Rivals
Huang’s warning – "Sanctions don’t stop China; they force it to build independent ecosystems" – manifests in three dimensions:
1. Innovation’s "Cocoon-Breaking Effect" Chip bans became China’s catalyst:
AMEC’s etching tools replaced U.S. equipment
ARM China’s non-U.S. IP cores bypassed sanctions
SMIC and Hua Hong raced toward 5nm breakthroughs History repeats: Like nukes and nuclear subs, China thrives under blockade.
2. The Silent Power Shift Huawei’s global footprint undermines U.S. tech diplomacy. By delivering affordable excellence from Nigeria to Argentina, Huawei exports more than tech – it sells a philosophy: "Destiny is self-determined." U.S. sanctions inadvertently fueled China’s tech evangelism.
III. Sanctions’ Legacy: Systemic Risks to U.S. Tech Leadership
Beyond immediate losses lie deeper threats:
1. Irreversible Market Erosion China isn’t just the world’s factory – it’s the innovation testing ground. Sanctions surrendered this advantage:
EV sector: Tesla now relies on Chinese factories while BYD and NIO dominate globally
5G/6G: Huawei leads 5G-A deployments as U.S. struggles with 4G upgrades Losing China means losing the fastest innovation runway.
2. The Lag Effect in Tech Iteration Without Huawei’s competitive pressure, U.S. firms risk complacency:
While Huawei hits 10Gbps with 5G-A, U.S. carriers patch 4G dead zones
As China commercializes solid-state batteries, U.S. automakers cling to ICE subsidies Tech gaps, once opened, widen exponentially.
IV. Lessons and Outlook: Why Tech Hegemony Always Falls
The Huawei saga mirrors history’s truth: No tech monopoly lasts. Ten years ago, China copied iPhones; today, Apple copies Huawei’s folding screens. This reversal reveals innovation’s core law:
True competitiveness springs from within – not from barricading others out.
For the U.S., sanctions taught bitter lessons:
Political interventions boomerang on domestic industries
Containment breeds stronger rivals
For the world, Huawei proved:
When a nation combines market scale, talent depth, and political will – no blockade is unbreakable.
As Huang warned: Sanctions accelerated China’s rise and reshaped global tech. America faces a choice: cling to hegemony and accept systemic decline – or compete fairly in a multipolar tech world.
