In an interview with the Nikkei News on May 18, Ren Zhengfei said that he was affected by the US ban.Huawei's growth is expected to slow, but the impact is local, with revenue growing at an annualised rate of less than 20 per cent. Between 2014 and 2018, Huawei's sales grew at a compound annual rate of 26 per cent.

Ren Zhengfei also said that Huawei "has never done anything against the law" and that US suppliers cannot supply Huawei with chips. "We have made preparations for this".

This is the first time Ren Zhengfei has been interviewed by the media since the United States blocked Huawei. On May 15, the Bureau of Industry and Security under the US Department of Commerce announced that Huawei would be included in the "entity list", and that enterprises or individuals on the list would need to obtain permission to purchase or transfer US technology. The United States will refuse to grant a license if it believes that the sale or transfer of technology endangers its national security or foreign policy interests.

Ren Zhengfei suggested that independent development be promoted through Hayes Semiconductor, a subsidiary of the group. He Tingbo, president of Shenzhen Haisi, a subsidiary of Huawei, sent a mass email to employees on Friday, May 17, saying that in the face of US pressure, Huawei would use a chip "spare tire" developed by itself for many years to achieve "technological self-reliance".

In the words of he Tingbo, Hayes's task is to create a "spare tire" for Huawei's survival. Huawei made the assumption of extreme survival many years ago, predicting that one day all advanced chips and technologies in the United States will not be available. "all the spare tires we have built have turned" positive "overnight! "

According to a list of 92 core suppliers disclosed by Huawei in November, 33 US suppliers were selected, while mainland suppliers ranked second with 25. Huawei spokesman Chase Skinner said earlier this year that Huawei buys $11 billion of products from the United States each year.

The 21st Century Economic report quoted sources in the semiconductor industry chain as saying that Huawei already has inventory of core components for half a year or so. Since last year, Huawei has been prepared to build inventory in advance to meet this year's challenges, and the spare tire strategy can also protect Huawei from some of the risks.
