in 1991, Turkmenistan and Uzbekistan became independent countries, making the Turkmenistan–Uzbekistan border an international border. A joint treaty was signed between Turkmenistan and Uzbekistan in 2000, recognizing the post-independence border as the official border between the two countries, ending a decade of disputes and establishing the border's current shape. A border fence was constructed afterward.

it was decided to divide Central Asia into ethnically-based republics in a process known as National Territorial Delimitation (or NTD). This was in line with Communist theory that nationalism was a necessary step on the path towards an eventually communist society, and Joseph Stalin's definition of a nation as being ''“a historically constituted, stable community of people, formed on the basis of a common language, territory, economic life, and psychological make-up manifested in a common culture”''. The NTD is commonly portrayed as being nothing more than a cynical exercise in

of the 1920s, closer analysis informed by the primary sources paints a much more nuanced picture than is commonly presented. The Soviets aimed to create ethnically homogeneous republics, however many areas were ethnically-mixed (e.g. the

, or the various Turkmen/Uzbek tribes along the Amu Darya).Bergne, Paul (2007) ''The Birth of Tajikistan: National Identity and the Origins of the Republic'', IB Taurus & Co Ltd, pg. 44-5 Local national elites strongly argued (and in many cases overstated) their case and the Soviets were often forced to adjudicate between them, further hindered by a lack of expert knowledge and the paucity of accurate or up-to-date ethnographic data on the region.Edgar, Adrienne Lynn (2004) ''Tribal Nation: The Making Of Soviet Turkmenistan'', Princeton University Press, pg. 53 Furthermore, NTD also aimed to create ‘viable’ entities, with economic, geographical, agricultural and infrastructural matters also to be taken into account and frequently trumping those of ethnicity. The attempt to balance these contradictory aims within an overall nationalist framework proved exceedingly difficult and often impossible, resulting in the drawing of often tortuously convoluted borders, multiple enclaves and the unavoidable creation of large minorities who ended up living in the ‘wrong’ republic. Additionally the Soviets never intended for these borders to become international frontiers as they are today. NTD of the area along ethnic lines had been proposed as early as 1920. At this time Central Asia consisted of two Autonomous Soviet Socialist Republics (ASSRs) within the

of the Soviet Union announced that it would proceed with NTD in Central Asia. The process was to be overseen by a Special Committee of the Central Asian Bureau, with three sub-committees for each of what were deemed to be the main nationalities of the region (Kazakhs, Turkmen and Uzbeks), with work then exceedingly rapidly. There were initial plans to possibly keep the Khorezm and Bukhara PSRs, however it was eventually decided to partition them in April 1924, over the often vocal opposition of their Communist Parties (the Khorezm Communists in particular were reluctant to destroy their PSR and had to be strong-armed into voting for their own dissolution in July of that year). The creation of Turkmenistan was hampered by a weak sense of Turkmen nationality, many of whom identified with their tribe first before that of the wider Turkmen identity. However, the Turkmen Communist elite pushed hard for the creation of a united

However ethnic identities along the Amu Darya were complex and it was often difficult to judge which groups were ‘Turkmen’ and which ‘Uzbek’ (e.g. the Salur, Bayad, Kurama, Ersarï, Khïdar-Alï etc.). Turkmen Communists pushed for a ‘maximalist’ Turkmenistan, opting to include all ambiguous groups as Turkmen. Their efforts gained them the cities of

And here we have our border issues too. We have borders on this and on that side as with the Kazakhs. We have already started to wire fences on the borders. You must provide all necessary support for this. Let there be crossing-points in specified areas. We are not doing this to separate ourselves from Uzbekistan or Kazakhstan but are doing so to maintain order on the border, to protect ourselves from violators and dishonest people and to prevent our goods from being smuggled. There are special crossing-points to prevent such things, and to ensure permitted and regulated border crossing on a legal basis. We have this in Koytendag astern Turkmenistanas well as in other border districts of Lebap Region. Yesterday we started this onstruction of wire fencesin Lebap, and earlier in Dashoguz. You must finish putting up this fence, all 1,700 km of it, by the end of this year. We need this to avoid any future dispute between us and to prevent any violators from entering. As we all are sovereign states, we cannot keep the borders open any more, for there could be trespassers from third countries.
Turkmenistan and Uzbekistan had serious "issues" regarding their mutual border until May 2004 when the Turkmen Foreign Ministry released a statement on May 31, 2004, saying disputes had been resolved.Dates Related to Elections, Officials, and Policy 2004
