Chinese telecoms equipment maker Huawei Technologies has released a report on cybersecurity that includes a pledge never to cooperate with spying in a fresh effort to allay security concerns that threaten to hamper its global expansion.
The report calls for joint global efforts to create a standard framework of laws and technical standards for security.
Suspicions that Huawei might be controlled by China's Communist Party or military have slowed its expansion in the US and it was barred from taking part in Australia's National Broadband Network.
The company has denied it is a security threat.
In its latest report, Huawei says it "will never support or tolerate" efforts to steal government intelligence or personal information.
The report is titled Cyber Security Perspectives: 21st century technology and security - a difficult marriage.
