Hi Sampath, just fyi to you, museums are legally obligated to give the origins of their content. It is completley false that they don't. Also anything that is within the possession of a country over 100 years becomes its own per international law. Even that has been challenged and treasures returned to their respective countries.
Making uninformed statements that ALL museum stuff is looted (perhaps some was over 100 years ago and left unchallenged. Also many preserved sculptures and work of art of Asia in museums in west are in much better condition than they would be in India.
