The China's telecom products are widely used in South Africa due to their good quality and being affordable, South African experts told Xinhua on Tuesday.

"The popular use of the China's telecom goods in South Africa is more than most people think. Many people use them, but they are unaware that they are China's goods like the Huawei USB internet modems distributed by South African mobile phone operators," South African information technology expert Bongani Mhlanga said in an interview with Xinhua.

On Oct.8, a US congressional panel alleged in its report that two leading Chinese telecom firms Huawei and ZTE were suspected to be involved in illegal behavior, posing possible threats to the U. S. national security.

Mhlanga said that there are various telecom brands from China, and their telecom products are competing in the South African markets. "Huawei and ZTE have gained a lot of respect all over the world for supplying quality goods and large investments," said he.

According to Professor Mthuli Ncube, the deputy president of the African Development bank, Huawei has invested a total of 1.5 billion USdollars in Africa.

In South Africa, the largest integrated telecom company Telkom contracted Huawei to deploy the next-generation ultra-broadband network in August 2012.

Altech, one of the high technology companies in the telecom listed in the Johannesburg Stock Exchange signed a deal with Huawei this year, making its customers to be possible to benefit from the Huawei's design, expertise and service.

Mhlanga said there is a potential market for China's telecom products like laptops, mobile phones, memory storage devices and software.

"The China's telecom firms are facing the challenge by the western companies in marketing their brands, and China's telecom firms should train more local technicians to service their products in South Africa,"the expert told Xinhua.

"The new Chinese brands are exploring the markets. South Africans tend to be loyal to the tried and tested products. Slowly, South Africans are beginning to accept more Chinese telecom products," the expert said.
