The basis is that Nokia is a bunch of idiots that actually tried to do manufacturing in India, showing all the judgment they did when they went with Windows Phone as a platform.
See, India's intelligentsia, by and large, doesn't like manufacturing. It might be necessary to some degree, but, offered a chance to replicate Taiwan or China's success by starting with cheap manufacturing, they'd decline. They want to jump straight ahead to a service/software economy via education rather than pass through an intermediate step of actually making physical things. So the basic self-interested counterbalances that you'd see elsewhere ("But we need to learn from Nokia so we can do this!" or "We need to treat Nokia well so others will build plants here too!") are weakened.
So, there's going to be a new owner for the factory, and thus there's an opportunity to extract protection money. After all, it's not like India wants manufacturing anyway.
