BRUSSELS (Reuters) -Azerbaijan said on Saturday that Russia and Armenia are not fulfilling the Nagorno-Karabakh enclave ceasefire deal, hours after the European Union urged Azerbaijan and Armenia to refrain from "violence and harsh rhetoric".
Since the collapse of the Soviet Union, Azerbaijan and Armenia have fought two wars over Nagorno-Karabakh, a small mountainous enclave that is part of Azerbaijan but populated by about 120,000 ethnic Armenians.
After heavy fighting and a Russian-brokered ceasefire, Azerbaijan in 2020 took over areas that had been controlled by ethnic Armenians in and around the mountain enclave.
"Armenia has not fulfilled many provisions of the statement, and Russia has not ensured the full implementation of the statement within its obligations," the Azeri foreign ministry said in a statement on its website.
Armenia and Azerbaijan have since been discussing a peace deal, in which Russia is also pushing to retain a leading role and in which the two countries would agree on borders, settle differences over the enclave, and unfreeze relations.
EU Council President Charles Michel hosted Azerbaijani President Ilham Aliyev and Armenian Prime Minister Nikol Pashinyan for talks in Brussels aimed at drawing a line under more than three decades of hostilities.
Armenia says the proposed peace treaty should provide special rights for them and guarantee their security. Azberbaijani Foreign Minister Jeyhun Bayramov rejected that demand in an interview with Reuters in June, saying it was unnecessary and amounted to interference in Azerbaijan's affairs.
"Real progress depends on the next steps that will need to be taken in the near future. As a matter of priority, violence and harsh rhetoric should stop in order to provide the proper environment for peace and normalisation talks," Michel said.
He told reporters: "The population on the ground needs reassurances, first and foremost regarding their rights and security."
Russia said on Saturday that it was ready to organise a three-way meeting with Armenia and Azerbaijan at the level of foreign ministers. This could be followed up with a Moscow summit to sign a peace treaty, the Foreign Ministry said in a statement.
It said an integral part of this pact should be "reliable and clear guarantees of the rights and security of the Armenians of Karabakh" and implementation of earlier agreements between Russia, Azerbaijan and Armenia.
Azerbaijan said the Moscow statement "causes disappointment and misunderstanding" and contradicts Russia's declarations of supporting Azerbaijan's territorial integrity.
Michel said he also expressed the EU's encouragement for Azerbaijan to talk directly to the Karabakh Armenians in order to develop confidence between the parties.
It was not clear how Aliyev reacted, as he and Pashinyan left without briefing reporters. The de facto leadership of Nagorno-Karabakh claims to be independent but is not recognised by any country.
Besides the EU, the United States has also been pushing the sides to reach a peace deal. Russia, the traditional power broker in the region, has been distracted by the war in Ukraine and risks seeing its influence diminished.
