France's foreign minister has voiced caution on Friday about President Viktor Yanukovich's announcement of a deal to end the Ukrainian political crisis, saying opposition leaders needed time to consult.
"The opposition wants to consult with some of its members, which is entirely understandable," Laurent Fabius said in a live interview on Europe 1 radio.
"In this sort of situation, as long as things haven't really been wrapped up, it's important to remain very cautious."
Fabius left Kiev during the night for Beijing but said he had been in touch with his colleagues, Frank-Walter Steinmeier of Germany and Radoslaw Sikorski, who stayed on to try to conclude the negotiations on Friday.
Ukraine's interim President has expressed concerns about signs of separatism as opposition in Russian-speaking regions grows.
Hundreds of Ukrainians and journalists flocked to the presidential palace, as reports emerged that President Yanukovich had left the city.
Vitali Klitschko was met with boos from anti-government protesters, as he attempted to convince them a peace deal is best course of action.
