Accepted Answer

Huawei Has Substituted Over 13,000 Components with Domestic Chinese Alternatives

Huawei founder Ren Zhengfei stated that over the past three years, the company has replaced more than 13,000 components affected by US trade sanctions with domestic Chinese substitutes. This initiative also involved redesigning approximately 4,000 circuit boards for its products, leading to a stabilisation in circuit board production. These efforts are part of Huawei's strategy to overcome US trade restrictions, which began in 2019 and have impacted its access to US chips and technology.
Component Replacement Initiative

The founder's remarks indicated a significant undertaking to identify and integrate domestically sourced alternatives for components previously supplied by international vendors. While specific details regarding the exact nature of these 13,000 replaced parts are not elaborated upon, the scale of the substitution highlights Huawei's commitment to self-sufficiency in its supply chain. This move is a direct response to the US export controls that have restricted Huawei's access to critical technologies.
Circuit Board Redesign

In conjunction with component substitution, Huawei has also redesigned 4,000 of its product circuit boards. This redesign effort suggests a comprehensive approach to adapting its hardware to accommodate the new domestic components. The stabilisation in circuit board production, as noted by Ren Zhengfei, points to the successful integration of these redesigned boards into the manufacturing process.
Response to US Trade Restrictions

The actions taken by Huawei are a direct consequence of successive rounds of US export controls imposed since 2019. These restrictions have not only cut off Huawei's access to chips from US companies but also to the technological tools necessary for designing its own chips and having them manufactured. The company's extensive component replacement and board redesign efforts demonstrate its resilience and adaptability in the face of these ongoing challenges.
