"After more than 20 years, the time has come to end suffering and hatred," Warlick said, added that it is time for all sides to work together for settlement based on principles of final Helsinki act.
"It is also time for co-chairs of the Minsk group and the Minsk group itself, for the governments of Azerbaijan and Armenia and the countries in the region to work together and take necessary steps for the settlement of the conflict for the peace and prosperity of the region," Warlick said.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 per cent 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 U.S. are currently holding peace negotiations.
Armenia has not yet implemented the U.N. Security Council`s four resolutions on the liberation of the Nagorno-Karabakh and the surrounding regions.
