Apple Inc said on Wednesday it appreciates the open and constructive dialogue that it held with Indian officials, around the expansion of its local operations in the country. Cupertino, California-based Apple, is keen to assemble its signature iPhones in India, one of the world's fastest growing smartphone markets where it still has only a tiny market share. Apple has demanded a series of tax and sourcing concessions from India, before it begins to assemble iPhones in the country, Reuters reported last week.
