The United Nations has branded the military operation in the troubled western state "ethnic cleansing". Suu Kyi did not address that accusation but said her government condemned rights violations and anyone responsible for abuses would face the law.
"We condemn all human rights violations and unlawful violence. We are committed to the restoration of peace and stability and rule of law throughout the state," Suu Kyi said in her address in the capital, Naypyitaw.
Long feted in the West for her role as champion of Burma's democratic opposition in the Buddhist-majority country during years of military rule and house arrest, Suu Kyi has faced growing criticism for saying little about the abuses faced by the Rohingya.
"Human rights violations and all other acts that impair stability and harmony and undermine the rule of law will be addressed in accordance with strict laws and justice," she said.
"We feel deeply for the suffering of all the people caught up in the conflict," Suu Kyi said.
Western diplomats and aid officials attending the address welcomed Suu Kyi's message, though some doubted if she had said enough to end the barrage of global criticism Myanmar has faced.
Human rights groups were dismissive. Amnesty International said Suu Kyi and her government were "burying their heads in the sand" for ignoring the role of the army in the violence.
'No clearance operations'
Myanmar's powerful military remains in full charge of security and Suu Kyi did not comment on the military operations except to say that since September 5, there had been "no armed clashes and there have been no clearance operations".
"Nevertheless, we are concerned to hear that numbers of Muslims are fleeing across the border to Bangladesh," she said.
"We want to find out why this exodus is happening. We would like to talk to those who have fled as well as those who have stayed. I think it is very little known a great majority of Muslims in the Rakhine state have not joined the exodus."
She said her government had been making every effort to restore peace and stability and to promote harmony between the Muslim and largely Buddhist Rakhine communities.
