China is continuing to cut down its use of technology from foreign providers as part of a cyber cold war with the US and other Western nations.
According to reports China has put Symantec and Kaspersky on its blacklist of companies that it does not want to do business in the country.
Local paper the People's Daily reported on the block through Twitter. "Govt procurement agency has excluded Symantec & Kaspersky fm a security software supplier list, all 5 in are fm China," it said, explaining that all five likely providers are now local.
A spokesperson for the Russian security firm Kaspersky told V3 that it is talking to the Chinese authorities about the situation.
"We are investigating and engaging in conversations with Chinese authorities about this matter," said a spokesperson. "It is too premature to go into any additional details at this time."
Symantec had not responded to a request for comment by the time of publication.
China has been cracking down on the use of technology from overseas vendors ever since the Snowden revelations first hit the headlines. Since then the US and China have come to numerous blows in cyber space. The US has accused military men of snooping on business such as utility firms and hacking into their networks, and in return China has accused the US of installing backdoors into kit that is exported to the East.
People's Daily added that the five firms on the official list are the local: Qihoo 360, Venustech, CAJinchen, Beijing Jiangmin and Rising.
In May V3 reported that Chinese authorities want to ban overseas software from its banks and financial institutions. Commenting after Edward Snowden's PRISM revelations come to light, China accused the US of underhand surveillance.
"The United States' spying operations have gone far beyond the legal rationale of ‘anti-terrorism' and have exposed its ugly face of pursuing self-interest in complete disregard of moral integrity," said Chinese authorities.
"These operations have flagrantly breached international laws, seriously infringed upon human rights and put global cyber security under threat. They deserve to be rejected and condemned by the whole world."
