During the question and portion round of the pageant, she was asked: "If you get to speak in front of the ASEAN leaders, what would be your message to the leaders?" She responded:[17][18]
"I believe that one of the biggest problems that our country faces today is divisiveness in politics, in religion and also in culture. And I believe that it is something that is the same across the world. And that is something I would want to address. I believe that when people can learn to tolerate each other's differences and respect each other's opinions, then we will just be a stronger nation and world."[17][18]
