"Pompeo has for some time constantly referred to China wherever he went, but his remarks were full of lies and fallacies. The U.S. side failed to produce convincing evidence for its allegations about "security risks" of Huawei and other Chinese enterprises. As we have stated many times, it is both unethical and disgraceful for the U.S. to suppress Huawei, a Chinese private firm, by resorting to state power and state apparatus on trumped-up charges."
Geng added that Chinese firms have performed well in spite of the U.S. suppression.

"I'd like to remind Pompeo that his rhetoric doesn't seem to sell well. As I learned from Huawei's website, as of June 6, Huawei had concluded 46 commercial contracts on 5G cooperation with 30 countries, including a few allies and European countries the U.S. had 'strenuously' attempted to dissuade from such cooperation."
The spokesperson said more and more people are showing an objective and unbiased stance on Chinese tech firms' participation in their countries' 5G construction, and an increasing number of countries are independently making choices in line with their own interests. 
While discussing Pompeo, Geng said "rumormongering, slandering and stirring up trouble everywhere will only end up damaging his own image and reputation, as well as undermining U.S. credibility in the world,".
