- US sanctions forced Huawei to make rapid shift in domestic chip innovation
- Engineers developed hundreds of chips under severe technological limitations
- National semiconductor chain expanded thanks to coordinated industry-wide response efforts
When the US Department of Commerce added Huawei to its Entity List on May 16, 2019, few observers anticipated the long-term consequences of that decision.
Huawei President Xu Zhijun has claimed that US restrictions on the company have unintentionally strengthened China’s semiconductor industrial chain.
He made the remarks while reflecting on years of export controls that limited Huawei’s access to advanced chip manufacturing and overseas supply chains.
Sanctions and change in strategy regarding semiconductors
According to Xu, those limitations forced both Huawei and the Chinese industry in general to accelerate internal development efforts at multiple technological layers.
Xu explained that Huawei’s reliance on external semiconductor manufacturing had become a critical limitation once trade restrictions intensified.
Previously, the company relied heavily on foreign foundries for the production of advanced chips, particularly for high-performance computer and mobile processors.
After sanctions cut off that access, Huawei was forced to reorganize its design and manufacturing approach under significantly tighter restrictions.
Huawei used available production capabilities instead of waiting for advanced external nodes, and this marked the beginning of broader structural changes.
According to Xu Zhijun, the pressure created by the restrictions spread beyond Huawei and influenced the broader semiconductor supply chain.
As for chip production, Xu is not excited about Huawei doing it now as they are a few years behind, but he appreciates the progress they have made so far.
“If it weren’t for the United States forcing our country, our company and our industry, we wouldn’t have been able to do something like this,” Xu Zhijun said.
“But I also thank the United States for allowing our country’s semiconductor industrial chain to really grow. Now the momentum is very good and everyone recognizes and supports it.”
Xu argued that sustained pressure led to greater investment in domestic design capabilities, manufacturing processes and supporting technological infrastructure.
The investments paid off, as the company last year launched the fastest AI chip in history despite tighter restrictions.
This shift reduced dependence on third-party suppliers while encouraging parallel development across multiple industry segments.
Internal response and restructuring efforts
Huawei’s response to US sanctions was positive and prioritized the continuity of existing products while internally expanding long-term chip development strategies.
The company also increased efforts to relocate production pathways and redesign hardware systems to be compatible with domestic manufacturing constraints.
During this period, engineers had to solve complex design challenges under significant technological limitations.
These efforts led to the creation of hundreds of chips adapted for alternative production environments within China.
At one point, Huawei was producing chips to ensure operational survival, but its efforts have expanded to broader industrial involvement across China.
Designers, manufacturers and research institutions had to collaborate vigorously to offer solutions because the ban created a huge market in China.
This collaboration contributed to a more integrated national semiconductor chain capable of reducing dependence on foreign technology sources.
While acknowledging current limitations in advanced manufacturing, he maintained that progress had been made at multiple stages of production.
