"We were on the side of the victors in World War I, unlike other Yugoslav peoples with whom we created a new joint state, which they bloodily left in the 1990s. With that, the past two decades completely obliterate the results of the Serb people's struggle in the past 100 years," Dacic said laying wreaths at the ossuary of the WW1 defenders of Belgrade.
He said he was not certain that the way the new state of Serbs, Croats and Slovenians created after WW1, in which he said Serbia had suffered the greatest losses, "advanced Serbia's national and state interest."
"That's why World War I should be a big lesson... We won a lot in war and lost in peace, as many said. One should think through what to do in peace. We must try to win in peace," Belgrade's media said reporting on Dacic's speech.
French Ambassador Francois-Xavier Deniau laid a wreath at the French military cemetery in Belgrade. German Ambassador Heinz Wilhelm, the head of the European Union Delegation to Serbia, Vincent Degert, senior Serbian officials and envoys of wartime associations of Serbia and France attended.
Deniau said the Serbs and the French had been "brothers in arms" since WW1. "Those were three long years during which French, Serb and allied soldiers sealed with blood this special link that continues to connect us, nearly a century later," he said.
Serbian President Tomislav Nikolic, visiting Greece, laid a wreath on Vido island, at the Blue Sea Tomb in the Ionian Sea where the remains of Serb soldiers were lowered in WW1.
Serbia is marking Armistice Day as a national holiday. It lost more than a million people in WW1, a third of its then population.
