Mr Cook will meet his French counterpart, Hubert Vedrine, to review progress and try to push the Serbs and ethnic Albanians towards a settlement to stop the fighting. However, speaking in the Commons yesterday, Mr Cook warned that a successful outcome was far from assured.
"In my statement to the House two weeks ago, I warned that I could not guarantee that the talks would necessarily end in agreement. That remains the case today," he said.
The international powers have set a deadline of noon on Saturday for a deal at the peace conference in the 14th-century chateau outside Paris. Serb negotiators appear to have backed down on the key demand to allow the ethnic Albanians wide-ranging self-rule.
The Kosovo Albanians also seem ready to sign a three-year interim agreement and tone down their demands for independence.
However the sticking point is whether the Serbs will agree to a Nato- led force coming into Kosovo to enforce the deal - which both the Albanians and the Americans have insisted upon.
The talks continued as the first contingent of British tanks, armoured vehicles and artillery destined for a possible role in a Kosovo peacekeeping force set sail.Reuse content
