Azerbaijan said that it has achieved the objectives for its military operation in Nagorno-Karabakh and that it was suspending all measures. In a statement, the Azerbaijani Ministry of Defence said "that taking into account the appeal of representatives of the Armenian residents of Karabakh received through the Russian peacekeeping contingent, an agreement was reached to suspend local anti-terrorist measures on September 20, 2023 at 13:00 on the following conditions: 1. The formations of the armed forces of Armenia and illegal Armenian armed formations  located in the Karabakh Region of the Republic of Azerbaijan lay down their arms, leave combat positions and military posts and completely disarm. Units of the Armenian armed forces are leaving the territory of Azerbaijan, illegal Armenian armed formations are being disbanded. 2. At the same time, all weapons and heavy equipment are surrendered. 3. The implementation of the above processes is ensured in coordination with the Russian peacekeeping contingent." The agreement has also been confirmed by sources close to the Armenian community of Karabakh. It has been further agreed that representatives of Baku and Stepanakert will meet tomorrow Thursday (21 September). The Azerbaijani military operation lasted exactly twenty four hours, during which dozens of casualties are reported on both sides.

US President, Joe Biden, on Tuesday (19 September) met in New York on the margins of the UN General Assembly, the leaders of the five Central Asian Republics. Attending the meeting were the presidents of Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan. This was the inaugural C5+1 presidential summit.   A readout from the White House said that the leaders discussed a range of issues, including security, trade and investment, regional connectivity, the need to respect the sovereignty and territorial integrity of all nations, and ongoing reforms to improve governance and the rule of law. 

Azerbaijan on Wednesday (20 September) continued its push into the territory of Nagorno-Karabakh despite international pressure to cease all hostilities. Throughout the night explosions could be heard across the territory as Azerbaijani artillery continued neutralising military objectives of the self-declared Nagorno-Karabakh Republic, which was set up by Armenians in the territory thirty years ago when they seceded from Azerbaijan. The world community still recognises Nagorno-Karabakh as part of Azerbaijan. Unconfirmed reports say that yesterday, only hours after the start of the operation, Azerbaijan managed to break through the line of contact around Martuni and Askeran, to the north and east of the main administrative town of the territory, Stepanakert. Since the Azerbaijani forces already hold the heights over Stepanakert from the south side, due to their control of the town of Shusha, this may suggest Azerbaijani forces are trying to encircle Stepanakert. There has been widespread condemnation of the Azerbaijani military offensive by the international community, with all countries, except Turkey, calling on Azerbaijan to end hostilities immediately. The UN Security Council is expected to meet tomorrow (Thursday, 21 September) in the afternoon New York time. It is not clear if a binding UN resolution can emerge, since the position of Russia and China remains ambiguous. It appears Azerbaijan is trying to achieve as many of its objectives as possible before that. In a conversation with US Secretary of State Antony Blinken, Azerbaijani president Ilham Aliyev said that the main objective of the operation was to disarm the illegal armed formations of the Armenian separatists. Azerbaijani spokespersons have repeatedly said that Azerbaijan is not seeking to expel the Armenian community from the territory and wants to see them properly integrated in Azerbaijani society. But the concern of the international community is that in the current atmosphere it is more likely that the Armenians will leave as the Azerbaijanis advance. Such scenario would mean that everyone has lost – the next hours will say how it is likely to go.

Azerbaijan' armed forces on Tuesday (19 September) around 1300 local time, launched a large-scale military operation in Nagorno-Karabakh. The Azerbaijani forces hit military targets with artillery and drones. There are now unconfirmed reports of movement of ground forces. The Azerbaijani government says it is responding to provocations, including an incident last night when several Azerbaijanis were killed as a result of a recently planted landmine. Armenian Prime Minister Nikol Pashinyan convened a meeting of the National Security Council to discuss developments. In a statement, he accused Azerbaijan of trying to embroil Armenia in a large-scale conflict, and said that Azerbaijan was pursuing in Karabakh a policy of ethnic cleaning. A statement issued by the Azerbaijani foreign ministry stated that "on September 19, the Armenian armed forces in the Karabakh region of Azerbaijan resorted to a series of large-scale military provocations and terrorist attacks." The Armenian government in a statement once more categorically denied that its armed forces were station in Nagorno-Karabakh. There have been no reports of incidents on the Armenia-Azerbaijan border. Behind the scenes there are intensive diplomatic efforts to try to stop the violence from escalating.

For a number of years, the United States has promoted a mechanism for dialogue with the five Central Asian Republics: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. Known as the C5 + 1 these meetings have usually be en held at the level of foreign minister. The first meeting was held in 2015, and the mechanism now also has a secretariat to ensure continuation between meetings. Today (19 September) in New York, US president Joe Biden will take the relationship further, by upgrading the dialogue to presidential level. This is both symbolic and significant. For a long time the United States has been accused of abandoning Central Asia, tacitly accepting that this was Russia's back yard. Well if it ever was, it no longer is. China has become an even more important player in Central Asia than Russia, and the Central Asian Republics are desperately trying to open up to the world. A slow, painful but hugely necessary process of reform is taking place in the five countries, in some pursued with more enthusiasm than others. At today's meeting, President Biden is expected to give encouragement to this reform process, but the key message will be one of support for the sovereignty, independence and territorial integrity of the five countries - a welcome message in the region given Russia's continued pressures.  Also on the US president's agenda will be Afghanistan, which neighbours a number of the C5 countries. And of course there is the issue of sanctions against Russia as a result of its invasion of Ukraine. Russia has been trying to use the Central Asian republics to circumvent the sanctions. This is an important issue for the international community and the US president will seek the best way to secure the support of the C5 governments.
