The Armenian parliament planned to hold the voting on a bill recognizing the independence of the separatist Nagorno Karabakh on Dec. 9, the PanArmenian website said.
The coalition forces said they would not participate in voting. The leader of the opposition party Heritage Raffi said this was a national issue. He urged the coalition to take part in the voting. As a result, the voting did not take place due to the lack of a quorum.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 percent of Azerbaijan since 1992, including the Nagorno-Karabakh region and seven surrounding districts.
Azerbaijan and Armenia signed a ceasefire agreement in 1994. The co-chairs of the OSCE Minsk Group - Russia, France, and the United States - are currently holding the peace negotiations.
Armenia has not yet implemented the U.N. Security Council's four resolutions on the liberation of Nagorno Karabakh and the surrounding regions.
