Nagorno Karabakh may join the negotiation process at a certain stage, said Matthew Bryza, US co-chairman of the OSCE Minsk Group.
"I think the Karabakh representatives will join the talks in the future. But it is not necessary to speak about changes in the format of the negotiation process", Bryza noted.
The US co-chairman of the OSCE Minsk Group also said that the new president of Armenia needs time for the further discussion of the problem.
