There has been an increasing focus by the Indian counter-intelligence agencies on the expanding presence, activities and business of the Chinese telecom giant Huawei, which is stated to have the largest mobile telephone business network in the world after Ericsson. Ever since the 1990s, there have been concerns in the Western countries over the suspected links of the company with the People's Liberation Army (PLA) and the Chinese intelligence agencies. The concerns initially started from the fact that the head of the company is a retired officer of the PLA. There were subsequent suspicions and allegations that many of its employees not only in China, but also in its overseas offices were either serving or retired officers of the PLA or the Chinese intelligence.
In fact,on the basis of the allegations made by the Washington Times in 2007, the US Committee on Foreign Investment in the US (CFIUS) made a review of the security implications of business deals between Huawei and some American companies. It called for a report on the subject from the office of the Director of National Intelligence.
Huawei, which greatly values its business in the US, took note of the security-related concerns being increasingly voiced in the US about the dangers of doing business with it and allowing it to acquire US companies, and reportedly volunteered to employ US citizens to supervise its contracts, which could have security implications. This offer was made following reports that it might be interested in acquiring a unit of the Motorola.
