The Shan State Army (SSA) settled in Thailand and developed a movement in Lwe Khay in northern Shan State. SSA headquarters was run by Chairman Khun Kyar Nu and secretary Set Say Wai. In the Lwe Khay region, it was led by Vice-Chairman Ohn Paung Pon Taing and Chief-of-Staff Sai Hla Aung. In March 1973, they removed Maha Daewi Nann Hein Kham as president. On 24 May 1973, the SSA joined the Koe Kant insurgent groups Law Sit Han, Maha Sann (from Bain Nginn) and Lai U (from Man Man Sai) in the Man Pa Laung Lwe Khay region.
