[5][6][7] The USDP was formed on 29 April 2010 by Thein Sein and senior military officers who had retired from the armed forces, in the lead-up to the 2010 Myanmar general election.

[8] On 6 July 2010, the military junta permitted its predecessor, the Union Solidarity and Development Association (USDA), to dissolve itself and transfer its assets and office to the USDP.

[8] This included assets from the USDA's conglomerate, the Myan Gon Myint group of companies, which had interests in key sectors of Myanmar's economy.

[11] Because of mounting criticism over his dual role, Thein Sein handed over the position of USDP chairman to Shwe Mann on 1 May 2013.

[6][22] In December 2022, the military junta began replacing hundreds of local government administrators in Yangon Region with USDP supporters.

[37][9] Myan Gon Myint was first established in 1995 with an initial US$500,000 investment, and earned US$2.7 million that year from selling and renting shops in Yangon's markets.

[37] USDP's economic activities are in potential violation of Myanmar's Political Parties Registration Law.
