The long-term presence of a United Nations Observer Mission and a Russian-led Commonwealth of Independent States peacekeeping force failed to prevent the flare-up of violence on several occasions.The autonomy of Abkhazia, which had functioned as a pro-Russian "buffer zone" in this troublesome region, was no longer needed by the Tsarist government and the rule of the Sharvashidze came to an end; in November 1864, Prince Mikhail (Hamud-Bey) was forced to renounce his rights and resettle in Voronezh, Russia.[citation needed] Russian general and a leader of White movement Anton Denikin laid claims on Abkhazia and captured Gagra, but Georgians counter-attacked in April 1919 and retook the city.Many Abkhaz opposed this, fearing that an independent Georgia would lead to the elimination of their autonomy, and argued instead for the establishment of Abkhazia as a separate Soviet republic in its own right.[89] On 23 July 1992, the Abkhaz faction in the republic's Supreme Council declared effective independence from Georgia, although the session was boycotted by ethnic Georgian deputies and the gesture went unrecognised by any other country.[108] In October, the Abkhaz and North Caucasian paramilitaries mounted a major offensive against Gagra after breaking a cease-fire, which drove the Georgian forces out of large swathes of the republic.Shevardnadze's government accused Russia of giving covert military support to the rebels with the aim of "detaching from Georgia its native territory and the Georgia-Russian frontier land".[citation needed] The Abkhaz forces quickly overran the rest of Abkhazia as the Georgian government faced a second threat; an uprising by the supporters of the deposed Zviad Gamsakhurdia in the region of Mingrelia (Samegrelo).[139][140] Since independence was recognised by Russia, a series of controversial agreements were made between the Abkhazian government and the Russian Federation that leased or sold a number of key state assets and relinquished control over the borders.In May 2009 several opposition parties and war veteran groups protested against these deals complaining that they undermined state sovereignty and risked exchanging one colonial power (Georgia) for another (Russia).[166] The United Nations has reaffirmed "the commitment of all Member States to the sovereignty, independence and territorial integrity of Georgia within its internationally recognised borders" and outlined the basic principles of conflict resolution which call for immediate return of all displaced persons and for non-resumption of hostilities.[167] Georgia accuses the Abkhaz secessionists of having conducted a deliberate campaign of ethnic cleansing of up to 250,000 Georgians, a claim supported by the Organization for Security and Co-operation in Europe (OSCE; Budapest, Lisbon and Istanbul declaration).It "regretted" the attempts to alter pre-war demographic composition and called for the "rapid development of a timetable to ensure the prompt voluntary return of all refugees and internally displaced persons to their homes."[170] On 28 March 2008, the President of Georgia Mikheil Saakashvili unveiled his government's new proposals to Abkhazia: the broadest possible autonomy within the framework of a Georgian state, a joint free economic zone, representation in the central authorities including the post of vice-president with the right to veto Abkhaz-related decisions."[172] On 3 July 2008, the OSCE Parliamentary Assembly passed a resolution at its annual session in Astana, expressing concern over Russia's recent moves in breakaway Abkhazia.The resolution calls on the Russian authorities to refrain from maintaining ties with the breakaway regions "in any manner that would constitute a challenge to the sovereignty of Georgia" and also urges Russia "to abide by OSCE standards and generally accepted international norms with respect to the threat or use of force to resolve conflicts in relations with other participating States.It stipulates that a special permit on entry into the breakaway regions can be issued if the trip there "serves Georgia's state interests; peaceful resolution of the conflict; de-occupation or humanitarian purposes."[207] The OSCE has increasingly engaged in dialogue with officials and civil society representatives in Abkhazia, especially from non-governmental organisations (NGO)s and the media, regarding human dimension standards in the region and is considering a presence in Gali.[211] On 5 October 2006, Javier Solana, the High Representative for the Common Foreign and Security Policy of the European Union, ruled out the possibility of replacing the Russian peacekeepers with the EU force.Acknowledging that the "new and tense situation" resulted, at least in part, from the Georgian special forces' operation in the upper Kodori Valley, the resolution urged the country to ensure that no troops unauthorised by the Moscow ceasefire agreement were present in that area.It urged the leadership of the Abkhaz side to address seriously the need for a dignified, secure return of refugees and internally displaced persons and to reassure the local population in the Gali district that their residency rights and identity will be respected.The Georgian side is "once again urged to address seriously legitimate Abkhaz security concerns, to avoid steps that could be seen as threatening and to refrain from militant rhetoric and provocative actions, especially in upper Kodori Valley.One of the early proposals was voiced before the war, in March 1989, when the Abkhaz ethno-nationalsit organization Aidgylara issued the Lykhny Appeal, calling for Abkhazia to become part of the Russian Soviet Federative Socialist Republic.[232] In August 2023, Deputy Chair of Russian Security Council Dmitry Medvedev also voiced support for these proposals, accusing Georgia of "escalating tensions" by its potential membership to the NATO, and saying that there were "good reasons" for Abkhazia and South Ossetia to join Russia.Although Abkhazia's complex topographic setting has spared most of the territory from significant human development, its cultivated fertile lands produce tea, tobacco, wine and fruits, a mainstay of the local agricultural sector.[244][245] According to a 2010 study published by the University of Colorado Boulder, the vast majority of Abkhazia's population supports independence, while a smaller number is in favour of joining the Russian Federation.During this period, the Government of Abkhazia in exile, led by Tamaz Nadareishvili, was known for a hard-line stance towards the Abkhaz problem and frequently voiced their opinion that the solution to the conflict can be attained only through Georgia's military response to secessionism.[citation needed] The Republic of Abkhazia is divided into seven raions (districts) named after their primary cities: Gagra, Gudauta, Sukhumi, Ochamchira, Gulripshi, Tkvarcheli and Gali.This provision aimed at creating a legal hurdle in obtaining Abkhaz passports for those ethnic Georgians who fled Abkhazia as a result of 1992–1993 armed conflict and who then returned to the Gali district.Opposition claimed that "massive" passportisation involving granting citizenship to ethnic Georgians in eastern districts was fraught with risk of "losing sovereignty and territorial integrity."
