Polish Foreign Minister Radoslaw Sikorski has said he sees no obstacles to the signing of the association agreement between the European Union and Ukraine.

"I do not know any formal facts that should say that it is impossible to sign the association agreement between Ukraine and the European Union," he said at a press conference following his talks with Russian Foreign Minister Sergei Lavrov.

Ukraine should take its own decision whether to sign the association agreement with the EU, Lavrov said for his part.

When asked to assess the prospects of Ukraine's signing this agreement at a press conference in Warsaw, the Russian foreign minister said that this question should be addressed to Ukraine.
