Some 600,000 people have crossed the border since August 25, when insurgent attacks on security posts were met by a ferocious counter-offensive by the Myanmar army.
Suu Kyi said in a televised address on Thursday evening that she would invite aid organisations and business leaders to take part in the initiative.
Domestic investigations, including a previous internal military probe, have largely dismissed refugees’ claims of abuses committed during security forces’ “clearance operations”.
Credible information indicates that the Myanmar security forces purposely destroyed the property of the Rohingyas and entire villages in northern Rakhine State.
The dramatic exodus of Rohingya Muslims from Myanmar’s northwest is putting pressure on Western policymakers to take action.
Any resolution imposing economic or military sanctions on Myanmar is likely to be vetoed either by China or Russia – or both.
There are an estimated 809,000 Rohingya sheltering in Bangladesh after fleeing violence and persecution in Myanmar.
Western governments that backed Suu Kyi’s campaign against military rule still see her as the best hope for Myanmar’s political and economic transition.
“The UN Security Council and concerned countries should impose targeted sanctions and an arms embargo on the Burmese military to end its ethnic cleansing campaign,” Human Rights Watch said.
The army dispatched about 500 soldiers to several towns near the border with Bangladesh on Thursday, including the towns of Buthidaung and Maungdaw.
The Myanmar military did not specify how many people were on board in its Facebook post.
