He claimed some states with interest in tourism were busy spoiling the name of Goa which attracts millions of holidaymakers, both domestic and international, every year.
Parrikar also alleged "a big news channel" has vested interest in "defaming" Goa.
"There is a big news channel which has vested interest in defaming Goa. They act as if they have the right over Goa. I have stopped watching the channel, let them carry what they want", he said.
Parrikar cited the life of revolutionary patriot Bhagat Singh to argue that there were two ways of looking at things. His remark was in context of some ministers visiting abroad to study garbage disposal systems.
"It was not a junket, it was a pre-operative expense. If I had not sent them, I would have been accused of constructing (waste treatment) plants without studying them," he said.
"There are two ways of looking at anything. We look at Bhagat Singh as a martyr but Britishers used to look at him at as a terrorist. We need proper prospective to look at everything," Parrikar added.
