Games involving the two Asian sides in recent times have descended into chaos as politics made it's way onto the field.
It will be the first time the teams face other since India's players refused to shake hands of their Pakistan counterparts following the Asia Cup final clash in September.
The rivalry took another unsavoury twist before the T20 World Cup when Pakistan threatened to boycott the game against India on instruction from the government.
The decision was reversed after intense negotiations between the ICC and Pakistan officials, with match set to take place in Colombo on Sunday.
"The game should be played in that spirit of cricket," Agha said. "What I expect doesn't matter.
"But I do feel the game should be played in the way it has been played since cricket started. Rest is up to them (India), whatever they want to do."
Both teams have won two from two so far at the global tournament but Agha has dismissed claims that his team will have an advantage as they are based in Colombo for the entire competition.
The Pakistan skipper said: "We are based in Colombo and playing all our matches here, but I don't know how that is an advantage.
"On the ground, you have to play good cricket, you will need to execute plans otherwise you can't win. Just because you are based here that doesn't mean you will win the match."
