In January 1947, Aung San and other AFPFL leaders such as Thakin Mya, Tin Tut, and Kyaw Nyein negotiated in London the independence for Burma. The British however made independence contingent upon the agreement of Burma's major ethnic minorities. Therefore, Aung San and other AFPFL colleagues among them Aung Zan Wai, Pe Khin, Bo Hmu Aung, Sir Maung Gyi, Myoma U Than Kywe and Sein Mya Maung took part in the Panglong Conference in February 1947 and convinced representatives from the Shan, Kachin, Chin and Kayah to support the negotiations for independence and join the future independent state of Burma.
