"We want to show the world, which allowed the genocide to happen, that we are still alive and that we still expect justice and the truth," she said.
The massacre - already classified as a genocidal act by the UN's International Criminal Tribunal for the former Yugoslavia - is Europe's worst atrocity since World War II.
In the case launched in 1993 by Bosnia's then Muslim-dominated government, Sarajevo accuses Belgrade of backing the widespread "ethnic cleansing" of its people during the war.
Filed against the then Yugoslavia, whose two republics Serbia and Montenegro have since split, it is the first time a country has accused another state of genocide, the gravest of war crimes.

Lawyers acting for Bosnia have argued that Serbia be found guilty of genocide or, alternatively, aiding and abetting genocide committed by individuals, groups and entities.
Bosnia has also asked the court to award reparation payments from Serbia that could reportedly amount to billions of dollars.
The case has been one of the most divisive issues within Bosnia, which was split into two political entities - the Serbs' Republika Srpska and the Muslim-Croat Federation - at the end of its 1992-95 war.
Bosnian Serbs, who account for about 30 per cent of the country's 3.8 million population, have backed Belgrade in the case by denying it committed genocide and agression against the country.
They have never hid their desire for the failure of the action, which alleges that systematic "ethnic cleansing" of Muslims and Croats was supported by the regime of late Serbian president Slobodan Milosevic.
The case is unique because it covers the whole of the war in Bosnia.
The International Criminal Tribunal for the former Yugoslavia (ICTY), the UN's ad hoc war crimes court, has handed down many verdicts relating to the Bosnian war, but they were limited to certain events or key people.
The only trial that tackled the whole of the Bosnian war and Serbia's involvement was the unfinished case against Milosevic.
The 16-judge ICJ panel is expected to take several hours to read its verdict.
The court's ruling is final with no appeal.
The prime minister of Bosnia's Serb-run half, Milorad Dodik, said last week his government was not prepared to accept any verdict.
"Republika Srpska will not accept the verdict and will not implement it," he said, calling the case illegal because the charges were filed during the war when Serbs were not a part of the government.
