(CNN) US Vice President Mike Pence told Myanmar's civilian leader Aung San Suu Kyi Wednesday that the treatment of her country's stateless Rohingya Muslim population was inexcusable.

"The violence and persecution by military and vigilantes which resulted in driving 700,000 Rohingya into Bangladesh is without excuse," Pence told Suu Kyi on the sidelines of the Association of Southeast Asian Nations summit in Singapore. "I'm anxious to hear about the progress you're making in holding those accountable who are responsible."

It comes as officials in Myanmar and Bangladesh get ready to repatriate more than 2,000 Rohingya refugees who fled a brutal military crackdown in Myanmar's Rakhine state last year.

The Myanmar military, known as the Tatmadaw, has been accused of using rape, murder and arson in a systematic campaign of ethnic cleansing that drove hundreds of thousands to flee to neighboring Bangladesh, where they languish in what has become the world's largest refugee camp. The Myanmar government has repeatedly denied that its soldiers deliberately attacked unarmed Rohingya.

Pence also brought up the jailing of two Reuters reporters who were sentenced to seven years in prison after being found guilty in September of breaching the country's Official Secrets Act.
