(QHA) -

Ukrainian Prime Minister Arseniy Yatsenyuk said on Wednesday that his government could not currently engage in bilateral talks with Russia, owing to the unrest in Ukraine and the annexation of Crimea.

He was speaking at a third round of domestic unity talks with Ukrainian politicians.

He also said that talks would be possible in the presence of EU and US officials, provided that the goals of a meeting were made clear beforehand.

The third round of Ukraine's national unity talks took place in Mykolaiv. The German government welcomed the third round of talks, also saying it was a "good sign" that a predominantly Russian city was chosen as the venue. Separatists from Donetsk and Luhansk have not been invited to the talks, with Yatsenyuk's government saying no participants could have "blood on their hands."
