"I will not offer a resignation as I did not violate the professional code of conduct," General Stojanovski was quoted by the France Presse Agency (AFP) as saying in Sofia, where he was on a visit on Monday.
On Friday, the Croatian judiciary announced launching an investigation into the case of General Stojanovski after local war veterans accused him of having been involved in war crimes while he was an officer of the JNA in Vukovar in 1991.
According to Macedonian Radio, Prime Minister Vlado Buckovski will travel to Zagreb on Tuesday to discuss this case, among other things, with his Croatian counterpart Ivo Sanader.
Before his trip, Buckovski was quoted as saying that Macedonia could not interfere into Croatia's internal matters and that the results of the investigation should be waited for. The Macedonian premier added that he did not want to see relations between Skopje and Zagreb deteriorate and that the Stojanovski case should not be a major topic in bilateral relations.
Two major opposition parties - VMRO-Narodna and VMRO-DPMNE - say they insist on the resignation of Stojanovski. If he fails to step down on his own, Macedonian President Branko Crvenkovski should dismiss him, the parties said on Monday.
