Walmart and Amazon didn't have a chance when they invested in Indian. Look into when WMT bought out flipkart. Then the Indian government passed a law to pretty much handicap Walmart and Amazon.

India is what brought down Enron, their loss in India is what they were hiding off their books.

To me any large company, specially non Indian company will have a hard time doing business in India. The Indian government doesn't like change, they fear anything that may cause social economical disruption.
