Matthew Bryza's statements should not be treated seriously while the U.S. should think over replacement of its Minsk Group mediator, an NKR official said.

"Bryza is a man who makes contradicting statements every day. The parties to talks do not pay attention to them as a rule," Vahram Atanesyan head of the NKR NA committee on external relations, told PanARMENIAN.Net.

"I am confident that Mr. Bryza did not know exactly what he wanted to say. But it's the problem of the State Department and Secretary Clinton, especially," he said.

"As far as I know neither NKR status nor 'return of territories' is negotiated at present. Political structure Bryza was speaking about is nothing but his productive imagination," Mr. Atanesyan said, adding that is talks are going on, it means that no agreement has been achieved yet.

OSCE Minsk Group Co-chair Matthew Bryza never said that "Karabakh will be returned to Azerbaijan."

"I said that according to Minsk Group's proposals the territories bordering on Karabakh will be step by step returned to Azerbaijan and refugees will come back as well. The future of Karabakh is the subject of talks. It will probably be a new political structure," Bryza told Ekho Moskvi radio station.
