Armenian Prime Minister Andranik Margarian did not rule out that the Karabakh problem will be discussed during the meeting of Vladimir Putin and George Bush in Bratislava, RFE/RL reports. In his words, taking into account that Russia and the US are the OSCE Minsk Group Co-Chairs, the Presidents of the two states are likely to discuss the Karabakh conflict among other regional problems. "I do not think that the US and Russian Presidents will come to decisions not known to the conflicting parties so far", Andranik Margarian noted.
