Bonn, 2 June 1999 (RFE/RL) - A joint mission to Belgrade by the special Kosovo envoys of the EU and Russia was briefly delayed amid reports they could not agree on a common set of peace terms to present to Yugoslav President Slobodan Milosevic. EU envoy Martti Ahtisaari and Russia's Viktor Chernomyrdin were expected to leave Bonn early this morning but instead they continued their own discussions together with U.S. Deputy Secretary of State Strobe Talbott. The envoys met until late into the night in a bid to reach a common position over peace principles set out by Russia and the G7 industrial democracies last month. German Chancellor Gerhard Schroeder, who joined the envoys for dinner, said they had made concrete progress. He said the talks focused "on who must get out and who must go in to protect the refugees and make their return possible."
