FRANKFURT -- Excluding Huawei's in setting up a 5G network in Germany would be blatant discrimination against Chinese companies and sends the wrong signal of protectionism, Chinese Ambassador to Germany Wu Ken said on Wednesday.

The Huawei ban will undermine Germany's own interests, said Wu in an address at the opening of China Day during the 22nd Euro Finance Week.

China hopes the German government will provide a fair, just and non-discriminatory business environment for all foreign enterprises, including Chinese companies, Wu said.

The ambassador said that Huawei has been working constructively with its German partners for nearly twenty years, spanning from 2G, 3G to 4G networks.

During a recent visit to Huawei's European headquarters in Dusseldorf, Germany, Wu said he learned that Huawei has created around 30,000 jobs directly and indirectly in Germany and made important contribution to the development of the local economy and digital economy in the country.

"If Huawei really were a threat to Germany's network security, why isn't there a single negative case so far? Why is there so much hype only when it comes to 5G construction?" Wu said.
