How Huawei and Xiaomi secretly helped China leap ahead in chip technology

What was meant to cripple China’s tech sector has instead fueled its resurgence. U.S. sanctions may have shut Huawei and Xiaomi out of Western supply chains, but those same restrictions sparked a wave of innovation that is now reshaping the global chip race.

The embargo that backfired

In 2019, Washington imposed sweeping sanctions on Chinese tech giants, blocking companies like Huawei from accessing advanced components made by Qualcomm, Intel, and others. The strategy was clear: slow Beijing’s momentum and maintain U.S. dominance in semiconductors.

But rather than collapsing, China doubled down. The government poured billions of yuan into research institutes, training programs, and above all, domestic chip manufacturing. While local foundries still lag behind Taiwan and South Korea in producing the most advanced 3- and 5-nanometer chips, the investment created a foundation for rapid catch-up.

Huawei and Xiaomi at the front line

The turning point came when Huawei shocked the industry by releasing its Kirin 9000S processor, built into the Mate 60 Pro smartphone. Manufactured by SMIC, the chip showed that China could design and produce advanced processors domestically—even under embargo.

Not far behind, Xiaomi began rolling out its own chips for camera image processing and power management, signaling that another Chinese giant was ready to wean itself off foreign suppliers.

These breakthroughs may not yet rival the performance of Qualcomm’s Snapdragon or Apple’s A-series chips, but they mark something far more important: China is no longer fully dependent on Western technology. Alongside this, Beijing is backing RISC-V, an open-source chip architecture that sidesteps the licensing controls tied to ARM and x86.

A strategy built on speed and scale

China’s approach to catching up is both aggressive and pragmatic. The playbook includes:

Massive subsidies for local foundries like SMIC.
Heavy investment in companies making chipmaking equipment.
Reverse engineering and rapid iteration, openly acknowledged as stepping stones to innovation.

This all-hands strategy reflects Beijing’s acceptance that progress can start with imitation, followed by improvement—and the results are beginning to show.

Growing alarm in Washington

In the U.S., the response has shifted from confidence to unease. Analysts now warn that within a decade, China could be producing its own high-end chips with no reliance on foreign suppliers. Such a milestone would fundamentally alter the balance of power in global technology.

For now, the U.S. still leads in the most advanced semiconductor processes. But the message from Beijing is clear: embargoes won’t halt China’s progress—they’ll accelerate it.

The bigger picture

Huawei and Xiaomi are more than just companies in this story—they are the public face of a national strategy. By transforming sanctions into fuel for innovation, China has proven that technological isolation can breed self-reliance.

The semiconductor war is far from over, but one thing is certain: the U.S. is no longer facing a passive rival. China’s fight to close the gap has begun in earnest, and the world is watching.
