"The whole world cheers every piece of good news and is sick every time they read about sectarian violence," he said. "Because everywhere on earth, people are tired of people killing each other and fighting each other because of their differences."
Clinton, who met earlier Thursday with Thein Sein, House Speaker Shwe Mann and opposition leader Aung San Suu Kyi, was officially in the main city of Yangon with his nonprofit The Clinton Foundation, which will help the government procure drugs for HIV/AIDS, malaria, and tuberculosis, tackle maternal and infant mortality, and improve agricultural development.
But it was clear, in a 40-minute speech before a tightly packed audience at the Myanmar Peace Center, that sectarian violence was not far from his mind.
He pointed to examples elsewhere across the globe where countries have been ripped apart by ethnic and religious conflict, including some during his own presidency the Balkans, the Middle East and Northern Ireland.
He spoke too about ways in which former foes managed eventually to put aside their differences and work together.
Myanmar's situation may be unique, its history complicated, he said, but "some lessons are applicable to everyone."
It's important to always remember, for instance, that no one is right all the time and that complicated problems are best solved by large groups with diverse experience and knowledge, he said.
