The medal is given to people who have performed outstanding acts of service; in the case of Aung San Suu Kyi, her bravery and courage in remaining under house arrest as a political prisoner for almost fifteen years, and for her unstinting promotion of democratic values and ideals.
The ceremony will take place in Washington on September 19th and will coincide with the Burmese leader's visit to the United States.
In addition to the congressional award, Suu Kyi will also be presented with the Atlantic Council's Global Citizen Award on Sept. 21 in New York.
Aung San Suu Kyi was eventually released from house arrest in 2010 and has since visited Thailand, where she was greeted wildly by thousands of Burmese migrants, and also in Europe, in particular Ireland, where she received Amnesty International's highest honour-the Ambassador of Conscience award- from U2's lead singer Bono in Dublin.
She said: ‘' I have discovered how much more people care. I had not expected this. I had not known how much they cared. This has come as a surprise to me and a very moving one".
Suu Kyi is feted across the world for her championing of democracy in the face of an often brutal military regime in her home country.
