General elections are scheduled for 3 October.
"We will make a law-based country and uproot poverty, the mafia and corruption," Radoncic told the press in Sarajevo on Monday.
Earlier this year he set up a party called "Alliance for a Better Future" (SBB). SBB lists were submitted to the Bosnian Central Election Commission for the forthcoming polls.
Radoncic's main rivals for the post of the Bosniak representative in the collective presidency are the current Bosniak member, Haris Silajdzic, and Bakir Izetbegovic of the Party of Democratic Action (SDA).
The main Croat candidates are Borjana Kristo of the Croatian Democratic Union of Bosnia-Herzegovina (HDZ BiH), Martin Raguz of the HDZ 1990, and Zeljko Komsic of the Social Democratic Party (SDP), who now sits in the presidency.
The main Serb candidates are the incumbent presidency member, Nebojsa Radmanovic of the Alliance of Independent Social Democrats (SNSD), led by the Serb entity's Prime Minister Milorad Dodik, and former Bosnian Foreign Minister Mladen Ivanic of the Party of Democratic Progress (PDP).
