Huawei Technologies Co. Ltd. has been allowed to participate in India's 5G trials, even as the Chinese telecom gear maker faces global scrutiny due to rising concerns about the security of its equipment, The Times of India reported.

The Indian government reportedly omitted Huawei and ZTE Corp. when it sent out initial invites seeking the engagement of companies for the country's 5G network. Huawei, which has already set up a center in India, protested, and an invitation from the telecom secretary was issued.

ZTE has still not been invited, the report said.

A Huawei statement cited in the report said, "Having proven a track record of doing business in the country, we continue to work closely with [the] government of India and other industry stakeholders."

Other global companies participating in the trials, and making presentations to the government authorities include Nokia Corp., Ericsson and Samsung Electronics Co. Ltd.

India has yet to voice its security concerns but is said to have an unofficial rule against Chinese investments in critical infrastructure projects.

U.S. officials have long cautioned companies against using telecommunications equipment from certain Chinese companies. SoftBank Corp. of Japan is also planning to remove equipment made by Huawei from its 4G network, while Australia has already banned Huawei from providing equipment for the country's planned 5G mobile network on national security grounds.
