It was her first address to the country about the violence in northern Rakhine state that has seen more than 400,000 Rohingya Muslims cross into Bangladesh.
Ms Suu Kyi has faced heavy criticism for her response to the crisis.
She said there had been no "clearance operations" for two weeks.
In her speech in English to Myanmar's parliament, Aung San Suu Kyi said she felt "deeply" for the suffering of "all people" in the conflict, and that Myanmar was "committed to a sustainable solution… for all communities in this state".
Ms Suu Kyi, who has decided not to attend the UN General Assembly in New York later this week, said she nevertheless wanted the international community to know what was being done by her government.
Hours after her speech, the UN Human Rights Council in Geneva called for full access to the region so it can investigate the situation "with its own eyes".
