Today's electronic network technology is the 4G era, but soon mankind will enter the 5G era. Many countries have begun to prepare for the establishment of 5G mobile broadband, but which company should complete this task? Huawei, a domestic enterprise in China, can provide the service of setting up 5G mobile broadband, and Huawei is actively expanding overseas markets for this purpose. However, Huawei, a China telecom giant, was boycotted in the United States because of its alleged espionage activities. Countries including the United States, Japan and New Zealand all rejected Huawei's related electronic business.

However, Huawei has not lost all its overseas business. Germany expressed its favor for Huawei and did not reject Huawei's 5G settings. Kleynhans, director of the Internet of Things security project of the New Responsibility Foundation in Berlin, Germany, also said that Germany should not blindly follow the boycott of Huawei by other countries, but should proceed from the facts and recognize Huawei's excellent products.

Regarding the suggestion of the United States that Huawei is suspected of espionage, Kleynhans believes that 45% of German 4G base stations are provided by Huawei, and there are no signs of industrial espionage so far. Therefore, Kleynhans believes that it is invalid to use 4G base stations to engage in industrial espionage, and Huawei obviously does not use 4G base stations to engage in industrial espionage. He believes that Huawei is credible and powerful.

Because Germany stood by Huawei in China and did not refuse Huawei's electronic services, the United States kept putting pressure on Germany. However, Germany did not give in, and even domestic officials agreed with Huawei. The director of the German Federal Information Security Agency even said that the US accusation against Huawei needs strong evidence to support it. German "strong support" changed the attitude of countries that followed suit and boycotted Huawei before, and began to re-understand China Huawei correctly and objectively!
