Huawei signed a deal with Russian telecoms company MTS on Wednesday, where Huawei will develop a 5G network in Russia over the next year.
Russia said Huawei would help build its new 5G network in a deal signed on Thursday, the first day of a three-day visit by President Xi Jinping of China. The 5G technology will usher in a major leap for all kinds of devices, especially those that are part of the so-called internet of things.
American authorities say that relying on Huawei equipment would open a window to possible Chinese surveillance of everyday life, with technical breaches possible.
Despite a history of vigilance about foreign spying with multiple laws intended to protect data, the Kremlin highlighted the agreement between Huawei and MTS, one of the three largest cellphone operators in Russia.
The Kremlin noted that several business deals had been signed in a ceremony attended by President Vladimir V. Putin and Mr. Xi.
Huawei, the world’s largest supplier of networking equipment, denies it carries out espionage or could be ordered to do so by the Chinese government.
The company has become a point of contention in the broader trade dispute between the United States and China, with other countries under pressure to decide whether to allow the telecommunications giant to help build their next-generation networks.
American authorities have pressed allies including Britain and Germany to ban Huawei and threatened to restrict intelligence-sharing with nations that let the company inside their networks.
