Kosor was commenting on a brief which Serbia has filed with the International Court of Justice (ICJ) in The Hague amending its genocide lawsuit against Croatia.

"We have no intention of withdrawing the lawsuit and the government led by the HDZ won't withdraw the lawsuit," Kosor said on the government's website, stressing that only the government was authorised to withdraw it and that it had never discussed or considered this matter.

"But this does not bring into question in any way our talks and negotiations on other issues," she said, adding that the most important outstanding issue between Croatia and Serbia was the people detained and gone missing during Croatia's 1991-95 Homeland War and that the key to solving it was in the records of the former Yugoslav army.

On 4 January 2010, Serbia's legal representatives filed a suit with the ICJ against Croatia for genocide against Serbs during the 1991-95 war. The lawsuit was Serbia's response to the genocide suit Croatia had filed with the ICJ in July 1999 against the then Yugoslavia.

Serbia's latest filing, according to the Serbian news agency Beta, consists of 320 pages and 76 supporting documents on approximately 1000 pages. Zagreb will now study the new arguments and reply, after which a hearing will be scheduled.
