India likely to block China's Huawei over security fears

India is likely to block its mobile carriers from using telecom equipment made by China's Huawei, two government officials said, under procurement rules due to come into force in June.

New Delhi is wary about awarding new technology business to Chinese firms both because of security fears and a desire to get Indian manufacturers to produce more telecoms equipment.

A U.S. campaign to curb Huawei has triggered bans or limits on the use of its equipment around the world but the situation in India has been amplified by strained relations between New Delhi and Beijing over their shared border.

India's telecoms department said on Wednesday that after June 15 carriers can only buy certain types of equipment from government-approved "trusted sources" and said New Delhi could also create a "no procurement" blacklist. Huawei is likely to feature on this embargoed list, the two officials, who declined to be named, told Reuters.

"We cannot prioritise economic gains if an investment poses national security risk," one of the officials said.

The telecoms department, which did not comment on Thursday about Huawei, is yet to provide further details on the plans for trusted sources or a procurement blacklist.

However, a third official, who also declined to be named, told Reuters that ZTE Corp, another Chinese firm, which has a smaller presence in India, could also be excluded.

Huawei and ZTE are under scrutiny for allegedly installing "backdoor" vulnerabilities to spy for the Chinese government.

Both have denied the allegations and Huawei has previously told Reuters it is ready to enter into a "no backdoor" deal with India to allay security concerns.

Huawei and ZTE did not immediately respond to requests for comment.

Two of India's three big telecoms carriers, Bharti Airtel and Vodafone Idea, use Huawei gear. Any restriction on Huawei gear is likely to push up costs, industry analysts say.

The Chinese firm's equipment and network maintenance contracts are typically cheaper than European competitors such as Ericsson and Nokia and there is limited availability of such gear in India.

India has begun to fast-track approvals of some of the more than 150 Chinese investment proposals worth over $2 billion it had put on hold after a June standoff between the two neighbours on the disputed Himalayan border.

"We have started giving some approvals to investment proposals even from China, but we will not give any approvals in sectors like telecom infrastructure and financials," a senior government official told Reuters.

The officials also said that India is unlikely to overturn last year's ban on more than 100 Chinese mobile apps or allow Chinese companies to bid for stakes in state-run firms such as Air India and refiner Bharat Petroleum Corp Ltd.

India plans to raise $23.57 billion in the 12 months from April 1 by selling state-run companies.

India's finance ministry did not respond to a request for comment.

The India-China border clash, the worst in nearly four decades, had soured already-fragile relations and "regaining trust would be a long road from here", one of the sources said.

India's technology ministry did not respond to a request for comment on app bans.
