India and China, along with basically every other country, have tons of regulations around how foreign companies can set up operations and invest in domestic markets.

You cannot do business without a local partners in many industries (read: a "joint" venture in which the local "partner" will acquire your IP and eventually compete with you down the road). Foreign ownership is restricted. It was big news when China mildly liberalized its laws earlier this year and only as a gesture in the ongoing trade disputes.
