India's fair trade regulator is investigating whether Google abused its dominance of the online advertising market.
In a regulatory filing released last week, Google revealed that its business practices were being investigated by the Competition Commission of India (CCI), as well as similar authorities in Argentina and South Korea.
A Google spokesperson told the Indian Express (IE) it was confident its products complied with India's competition laws.
"We're always happy to answer questions about our business and we're extending our full cooperation to CCI," the spokesperson told IE.
According to Parliament records, the investigation began over six months ago when consumer advocacy group Consumer Unity and Trust Society (CUTS) International complained to the CCI that Google practised anti-competitive behavior.
In August 2012, the CCI began investigating whether Google contravened section 4 of the Competition Act, 2002.
Complaints from online matchmaker
Last February, online matchmaker Bharat Matrimony filed an antitrust complaint against Google with the CCI. The company, which facilitates marriages between people from the same ethnic group, complained that Google abused its market position by allowing rivals to buy search keywords associated with its Web sites, including TamilMatrimony.com and BengaliMatrimony.com.
