Two weeks after the signing of the agreement with Britain, Aung San signed an agreement at the second Panglong Conference on 12 February 1947, with leaders representing the Shan, Kachin, and Chin People. In this agreement these leaders agreed to join a united independent Burma, under the condition that they would have "full autonomy" and the right to secede in 1958, after ten years. Karen leaders were not consulted and were not a part of the agreement. They hoped for a separate Karen State within the British Empire. The date of the signing of the Panglong Agreement has been celebrated in Burma as "Union Day", even though Ne Win effectively dissolved any agreement with Burma's minority communities following his coup in 1962.
