Armenia should observe UN resolutions and decisions and liberate the occupied Azerbaijani lands, the UN top official said.
The Secretary General of UN World Tourism Organization Taleb Rifai, who is on visit to Baku commented on the issue regarding destruction of the tourist zones in the occupied Azerbaijani lands.
UN top official stressed that international law is very important on this issue.
"I hope that time, good reason and diplomacy will resolve all these issues," he 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.
