The death of Georgian Prime Minister Zurab Zhvania may have a negative effect on settling the nation\'s conflict with the self-proclaimed republic of South Ossetia, Tskhinvali sources said. \"South Ossetian President Eduard Kokoity deeply regrets the tragic death of Zurab Zhvania and has extended his profound condolences to the Georgian people over this loss. He believes that Zurab Zhvania played a highly positive role in the Georgian-Ossetian settlement process and does not rule out that the negotiating process may now become more complicated,\" Irina Gagloyeva, head of South Ossetia\'s information committee, told Interfax from Tskhinvali on Thursday.
