Australia and New Zealand have already blocked Huawei from building 5G networks. Britain’s BT Group said on Wednesday it was removing Huawei’s equipment from the core of its existing 3G and 4G mobile operations and would not use the company in central parts of the next network.
Japan’s chief government spokesman, Yoshihide Suga, declined to comment. But he noted that the country has been in close communication with the US on a wide range of areas, including cybersecurity.
“Cybersecurity is becoming an important issue in Japan,” he told a regular news conference. “We’ll take firm measures looking at it from a variety of perspectives.”
