China's Commerce Ministry said Australia's ban on Chinese technology giant Huawei Technologies from bidding to help build a nationwide high-speed Internet network is "unjust."
Australia said the ban is due to concerns about cyber attacks traced to China .
Ministry spokesman Shen Danyang said late Friday that Australia should not exclude Huawei from participating in a fair competition in the name of security.
Danyang said Huawei has provided broadband network equipment and services for many countries and has operated in Australia for nearly a decade.
The ban highlights concern about a spate of hacking attempts aimed at Western companies and the role of Chinese equipment providers, which are expanding abroad.
China protests being shut out of Australia’s broadband projects.
