Huawei Technologies has replaced more than 13,000 parts in its products that were hit by United States trade sanctions, the Chinese tech giant’s founder said, according to a speech transcript posted on Friday (Mar 17) by a Chinese university.

According to the transcript of the February speech posted by Shanghai Jiao Tong University, Ren Zhengfei said that Huawei had over the past three years replaced the 13,000 components with domestic Chinese substitutes and had redesigned 4,000 circuit boards for its products.

He said production of circuit boards had “stabilised”.

The remarks, which Reuters could not independently verify, provided a window into Huawei’s efforts to bounce back from US trade restrictions.
