It would appear that Nokia isn't too keen on India these days. At least from a manufacturer's stand point. The issue at hand seems to be a hefty tax bill that has the Windows Phone OEM considering the country its "least favourable" market to operate in.
Nokia is fighting a $20 Billion rupee tax demand from the Indian Government (about $311 million U.S.). A tax burden that may have Nokia move the manufacturing of their mobile phones to China and import them to the Indian market.
