China is deeply concerned over Australia’s decision to ban Chinese telecom equipment company Huawei from participating in local broadband network contracts, reports China Daily.

It quoted Shen Danyang a spokesman with China''s commerce ministry as describing the decision as "unjust".  He said China is "deeply concerned" over the matter.

Last month Australian government had excluded Huawei Technologies from bidding for work on a 35.9-billion-Australian-dollar high-speed broadband network for cyber security reasons.

Australia should not expel Chinese companies from fair market competitions in the name of security, Shen said.

Huawei has provided broadband network equipment and services for many countries around the globe, and Huawei Australia, which was bidding for the contract, has been operating in Australia for almost 10 years without any unfavorable record, he said.

Nearly 90 percent of employees of Huawei Australia are Australian, Shen added.

The spokesman stressed that China and Australia have signed a bilateral investment treaty, and that trade and economic cooperation have boomed between the two countries in recent years.

Therefore, both sides should create a fair and discrimination-free market environment and promote the healthy development of Sino-Australian economic and trade cooperation with an open, cooperative and constructive attitude, he said.
