Chinese telecoms equipment maker Huawei Technologies Ltd. has issued a report on cybersecurity that includes a pledge never to cooperate with spying in a fresh effort to allay concerns in the United States and elsewhere that threaten to hamper its expansion.

According to The Associated Press, the report, written by a Huawei executive who is a former British official, calls for global efforts to create legal and technical security standards. It makes no recommendations for what standards to adopt but says current laws are inconsistent or fail to address important threats.

Huawei, founded by a former Chinese military engineer in 1987, has grown to become the world's second-largest supplier of telecoms network gear after Sweden's LM Ericsson.

Suspicions that Huawei might be controlled by China's Communist Party or military have slowed its expansion in the United States and it was barred from bidding to take part in an Australian broadband project.

The company denies it is a security threat.

The 25-page report was written by John Suffolk, a former British government chief information officer who became Huawei's global cyber security officer last year.

A Huawei spokesman said the report was not intended as a direct response to security concerns about the company in the United States, Australia and elsewhere.

Huawei was barred from bidding to work on a planned Australian high-speed Internet network due to concerns about cyberattacks traced to China. The company had to unwind its purchase of a U.S. computer company, 3Leaf Systems, last year after it failed to win approval from a government security panel.

A U.S. congressional panel has said it will investigate whether allowing Huawei, rival ZTE Corp. and other Chinese makers of telecoms gear to expand in the United States might aid spying by Beijing.
