Ukrainian Prime Minister Arseny Yatsenyuk has rejected Russian peace proposals for Ukraine, saying they are an attempt to deceive the West on the eve of the NATO summit in Wales and to avoid new sanctions against Moscow.
Moreover, Ukraine is beefing up its border with Russia, and seeking special partner status with NATO, Yatsenyuk announced.
Pro-Russian separatists have been fighting against government troops in eastern Ukraine since April.
Kyiv and the West accuse Russia of sending troops and weapons to reinforce the rebels, which Moscow denies.
Earlier on September 3, after a telephone conversation with Petro Poroshenko Russian President Vladimir Putin said he had "sketched out" a seven-point cease-fire.
