if bitcoin will be famous there and greatly adopted i'm sure they will build one, for now there are alternative like localbitcoin, you can also use other exchange with wire transfer
they should support a large range of countries, i doubt india isn't there...
There is an exchange for India called igot.com and is a fraud exchange.
And they charge about50k satoshi in order to withdraw and there is a friend of mine who requested for a withdraw and there have been many days and still have not got the funds and is still showing pending for withdrawl.
So if these things keep on happening then people will not trust in bitcoins and not use it.
So for adaption by people we need honest exchanges.
