[2] The UFD supported President Pascal Lissouba during that period,[3] and Abandzounou was appointed to the government as Minister-Delegate for Relations with Parliament on 23 January 1995.

In anticipation of the 2002 parliamentary election, the UFD signed an electoral alliance with President Denis Sassou Nguesso's Congolese Labour Party (PCT) in late 2001.

In a statement on that occasion, Abandzounou said that the alliance was for "democracy and free expression, the establishment of the rule of law, and the irreversibility of political change through the ballot box", and he praised the commitment of Ganao and Sassou Nguesso to peace and reconciliation.

[12] On 12 November 2005, Abandzounou founded a political association, the Action Committee for Progress (Comité d'action pour le progrès, CAP).

[20] At a special session of the CAP National Council, held on 13 January 2007 at Makabandilou in Brazzaville, the association was converted into a political party[14][19] so that it could run candidates in the 2007 parliamentary election.

[17] As Djambala was considered the stronghold of support for both the UFD and the newly established CAP, the 2007 election was hotly contested and the outcome was crucial for both parties.

[24][25] A large coalition of parties and associations supporting Sassou Nguesso, the Rally of the Presidential Majority (RMP), was established on 20 December 2007,[26] and the CAP joined it.

[27] With his party having failed to obtain representation in the National Assembly, Abandzounou was dismissed from the government on 30 December 2007;[28] he passed control of the Ministry of Scientific Research to his successor, Hellot Matson Mampouya, in January 2008.

[33] Abandzounou was appointed as Ambassador to Equatorial Guinea and presented his credentials to President Teodoro Obiang Nguema Mbasogo on February 19, 2018.
