Agreement on Friendship and Cooperation between Bosnia and Herzegovina and Croatia
On 21 July, Izetbegović and Tuđman signed the "Agreement on Friendship and Cooperation between the Republic of Bosnia and Herzegovina and the Republic of Croatia" in Zagreb, Croatia. The agreement allowed them to "cooperate in opposing [the Serb] aggression" and coordinate military efforts. It placed the HVO under the command of the ARBiH. Cooperation was inharmonious, but enabled the transportation of weapons to ARBiH through Croatia in spite of the UN sanctioned arms embargo, reopening channels blocked by Boban. It established "economic, financial, cultural, educational, scientific and religious cooperation" between the signatories. It also stipulated that Bosnian Croats hold dual citizenship for both Bosnia and Herzegovina and for Croatia. This was criticized as Croatian attempts at "claiming broader political and territorial rights in the parts of Bosnia and Herzegovina where large numbers of Croats live". After its signature Boban vowed to Izetbegović that HR-HB would remain an integral part of Bosnia and Herzegovina when the war ended.
