KIEV, Oct 6 - Ukraine is working hard with the European Union to prepare a free trade agreement but it is not clear if it will be ready for signing at a summit in late November, Prime Minister Mykola Azarov said Wednesday.

Speaking to journalists in Helsinki, Azarov said he would travel to Brussels on October 13-14 to have further talks with the bloc on a possible free trade zone which forms the core of a future Association agreement between the sides, Reuters reported.

"It is not important when this is signed. What is important is the nature of the document," he said in televised comments. "Let's not rush forward too quickly.

The question of our trade cooperation is not a simple one," he said.
