The incident this week came after the opposition leader, former political prisoner and 1991 Nobel Peace Prize recipient backed a government report recommending the copper mine in northern Myanmar remain open.
The visit to the village of Tone, where people have been displaced and put out of work at the Chinese-financed mine, included protesters expressing disappointment in her position, the Voice of America reported Friday.
"There must be profits for local investors so our country is not only for the local people but for people in the whole country. That's why I agreed to continue the project this way, and that's why I advise this project should continue," she said during her visit.
Her position failed to impress locals, who noted her investigation committee failed to identify those responsible for police use of white phosphorus against protesters in November, Voice of America noted.
