"That decision will only do harm to our armed forces," Pokaz said at a news briefing.
Pokaz said that the Parliament's decision showed that it was necessary to change the decision-making procedure regarding the sending of Croatian troops to peace-keeping missions or military exercises.
Such a decision requires approval by a two-thirds parliamentary majority, and Pokaz said that the whole procedure was too complicated.
Pokaz said that Croatia was seeking ways of arranging training for its military officers in the United States and receiving donations in equipment from the US.
As good examples of bilateral cooperation, Pokaz cited a recent visit by a Croatian army platoon to the National Guard in Minnesota and its participation in a military exercise.
Cooperation has been arranged for the next year as well as a visit by a US platoon from Minnesota to the Croatian armed forces, Pokaz said.
Last Friday the decision on sending Croatian troops to international military exercises was supported by 101 members of Parliament, one short of the required two-thirds majority.
