The United States has piled pressure on its allies to shut out Huawei Technologies, the leading telecoms equipment vendor with a global market share of 28%, saying its gear contained “back doors” that would enable China to spy on other countries.

Hungary has said however it had no evidence that Huawei equipment would pose a security threat and Foreign Minister Peter Szijjarto announced at an event in China on Tuesday that Hungary would involve Huawei in the 5G rollout.

Szijjarto said Huawei would cooperate with Vodafone and Deutsche Telekom in the Hungarian 5G rollout according to an emailed Foreign Ministry statement.

Deutsche Telekom’s Hungarian unit said Huawei was just one of the suppliers tested for the 5G technology.

Hungary published the draft documentation for the sale of more than 400 megahertz of 5G spectrum in June, aiming for a commercial start of the service at main industrial facilities next year.
