[global network reporter Cui Yan] according to Reuters, on August 13, Ellen Lord, deputy secretary of defense in charge of procurement, said that a new regulation prohibiting the U.S. government from purchasing products or services from enterprises that “use the products of five specific Chinese companies” has come into effect on August 13. The five Chinese companies include Huawei, Hikvision, Dahua, hytera and ZTE. The regulation will have a “profound impact” on companies that sell products and services to the U.S. government, as they now need to prove that they are not using products from Zhejiang Dahua Technology Co., Ltd. or Hangzhou Hikvision, the world’s leading suppliers of surveillance equipment and digital cameras, according to the report. According to reports, the regulation also applies to two-way radio transceivers of Shenzhen hainengda Communication Co., Ltd., as well as mobile devices such as Huawei and ZTE’s communication equipment or smart phones. Recently, western countries, led by the United States, have repeatedly excluded and sanctioned Chinese science and technology enterprises for “national security”. In mid May, the U.S. Department of Commerce announced a new regulation to cut off Huawei’s chip supply chain. On June 24, Huawei and Hikvision were listed in the so-called “Chinese military owned, controlled or contacted” list. On June 30, the Federal Communications Commission (FCC) listed Huawei and ZTE as “national security threats”. Zhao Lijian, spokesman of the Chinese Ministry of foreign affairs, has already made a response to the US’s frequent crackdown on Chinese enterprises at the press conference. Zhao Lijian pointed out that the US side is accustomed to abusing state power and suppressing specific countries and enterprises with no evidence. This kind of economic bullying by the United States is a blatant denial of the principle of market economy that the United States has always flaunted. However, China’s Foreign Ministry spokesman Hua Chunying said on July 17 that the United States would implement the national defense authorization law on August 13 to prohibit government contractors from using the products of five Chinese enterprises, such as Huawei. China’s Foreign Ministry spokesman Hua Chunying said on July 17 that the United States had no evidence to prove that Huawei and other Chinese enterprises posed a threat to the security of the United States. Huawei’s biggest “mistake” is that it belongs to China, that is, it is more advanced than the United States in 5g field. It seems that the United States can’t tolerate any other country having something better than it. Therefore, the United States has suppressed Chinese enterprises such as Huawei with unwarranted charges and abuse of state power. This is a kind of economic bullying and a blatant negation of the principle of market economy that the United States has always flaunted. Countries all over the world see this very clearly. Hua Chunying said: we urge the US side to stop generalizing the concept of national security, stop deliberately vilifying and accusing China, and stop unreasonable crackdowns on specific Chinese enterprises, so as to provide a fair, just and non discriminatory environment for Chinese enterprises to operate in the United States normally. American enterprises hope that China will provide them with a fair, just and non discriminatory environment. However, they should also think carefully about which country’s enterprises, like those of China’s Huawei, have been treated unfairly, unreasonably and brutally in the United States? I think that countries and people with a sense of justice should stand up and speak out.
