Speaking in Hungary, the first stop in the European tour of five nations, Pompeo said that the United States is obliged to inform other governments of the risks of building networks with telecommunications giant equipment Chinese.
"What's crucial is that we share what we know about the risks that show Huawei's presence in their networks," he said. "Real risks to themselves, to lose loss of privacy for themselves, is the danger that China uses these data in a way that is not for the benefit of Hungary."
If countries use Huawei equipment, "it makes us harder to get involved with them," said Pompeo.
The United States government was suspected that Beijing could use Huawei equipment for spiral but did not provide public evidence to support those concerns. Washington has now been around the world to keep Huawei from the next generation of wireless networks, known as 5G.
There is a particular concern regarding 5G security as it will be used to make large amounts of data that connect robots, autonomous vehicles and other devices that may be sensitive.
China's famous Huawei, who is one of the best smart manufacturers in the world, has repeatedly has its own national security risk. It also maintains that it is a private-owned company and is unrelated to the Chinese government.
Huawei uncertainty throughout Europe
Huawei is largely of the US market, but the company has a significant business in Europe where it has 40% of the telecommunications equipment market.
Washington wants to release that arrest.
World mobile carrier Vodafone ( VOD ) said late in the last month that it was suspending the deployment of Huawei equipment in core networks in Europe, due to political uncertainty around the Chinese firm.
In the United Kingdom, Huawei is spending $ 2 billion on efforts to address the security concerns of government agencies. The telecommunications operator BT ( BT ) worked that does not purchase Huawei equipment at the core of its 5G network but would continue to be used for other parts, such as example of mobile base stations.
The German Chancellor Angela Merkel said last week that "big talk about Huawei" in Germany is because the country will develop 5G networks. "We need to talk to China to ensure that all the companies do not use data used to the Chinese state," she said, adding that "safeguards" needed to protect data.
What will Canada do?
Two US assistance outside of Europe has already survived from Huawei. Australia and New Zealand restricted the company last year to supply equipment for 5G networks.
Huawei broke back against his "unreasonable decisions" by some countries saying he was based on "judicial considerations" scientific and geopolitical "rather than legitimate concerns about technology.
Canada is considering similar measures to restrict Huawei even as it goes on a geopolitical basis between Washington and Beijing. Canadian police chief Huawei Meng Wanzhou held Finance in December on behalf of the United States authorities. Meng daughter is the Huawei owner, Ren Zhengfei.
China has a serious relationship between China and Canada.
The US Department of Justice wants to request Meng extradition, urging itself to Huawei for bank fraud and violating US sanctions on Iran. Meng and Huawei denied the charges.
