Sheikh Mohamed bin Zayed pledged his support for peace efforts between Armenia and Azerbaijan.
During a meeting with Armenia's president, Armen Sarkissian, in the UAE capital, the Crown Prince of Abu Dhabi and Deputy Supreme Commander of the Armed Forces welcomed the Russian-brokered ceasefire to end the fighting over Nagorno-Karabakh.
Armenia and Azerbaijan agreed to stop hostilities after weeks of fighting in the latest spill-over of tensions between the two nations over the disputed region, which is called the Republic of Artsakh by Armenia.
"While meeting the Armenian President Armen Sarkissian in Abu Dhabi, we discussed strengthening the relationship between our two countries," Sheikh Mohamed said on Sunday.
"We also expressed our support for a ceasefire between Armenia and Azerbaijan, and peace and stability in the region."
Writing in The National last month, Mr Sarkissian said "we need to understand that there is no military solution to this and, I would say, to any conflict. Armenians have always believed that a solution has to be reached through peaceful negotiations and in a way that does not make things worse".
