On 13 July, the government of Netherlands, then the presiding EC country, suggested to other EC countries that the possibility of agreed changes to Yugoslav Republics borders could be explored, but the proposal was rejected by other members. In July 1991, Radovan Karadžić, president of the self-proclaimed Republika Srpska, and Muhamed Filipović, vice president of the Muslim Bosniak Organisation (MBO), drafted an agreement between the Serbs and Bosniaks which would leave Bosnia in a state union with SR Serbia and SR Montenegro. The Croatian Democratic Union (HDZ BiH) and the Social Democratic Party (SDP BiH) denounced the agreement, calling it an anti-Croat pact and a betrayal. Although initially welcoming the initiative, Izetbegović also dismissed the agreement.
