of state territories – the division of the world into nation states. They 
were seen as signs of the territorial integrity and sovereignty of the state. 
Since then, the state territory looks like a whole entity, separated from 
neighbours by clear geometric lines. In addition to arguments in favour 
of self-determination and linguistic separation, claims for acquisition and 
alteration of borders are also based on the idea of “natural borders”. 
Border and territorial disputes are worldwide actual topic for scientic 
research, including the countries of the post-Soviet area. The principles of 
territorial integrity and the inviolability of borders are central to modern 
system of international law, they are democratic governing source of 
international law and norms of a universal character (Corten, 1998). 
The problems of territorial disputes remain relevant for both domestic 
and foreign researchers. In Ukraine, various scholars have devoted attention 
to the problems of the legal formalization of the state border.
Adamchuk I. studied forms and methods of changing existing inter-
state borders which were legalized by international law during the interwar 
period (1918–1939), as well as Soviet compliance with the requirements 
and  norms  of  existing  international  law  during  the  reunication  of 
Northern Bukovyna and Transcarpathian Ukraine with Soviet Ukraine 
(Adamchuk, 2010). In their work, Kyslovskyi and Truhan made a research 
of the problems of dening the frontier of internal sea waters as a part of 
sovereign maritime territory with a view to demilitarizing maritime area 
(Kyslovskyi and Truhan, 2012). 
The  current  сondition  of  public  administration  in  the  sphere  of  legal 
formalization of the state border was researched by Sitsinskyi V. He made 
the conclusion that the legal formalization of the state border of Ukraine 
throughout its length is a key foreign policy priority of national security of 
Ukraine (Sitsinskyi, 2012). 
Sitsinskyi N. noted that the State border of Ukraine is not legally 
formalized and does not allow the introduction of effective mechanisms 
of public administration to protect the sovereignty, territorial integrity, 
and independence of the state. It is also impossible to introduce effective 
mechanisms for ensuring the regime of the state border, in particular the 
procedure for its maintenance and the development of the relevant border 
infrastructure and conduction of economic and environmental activities, 
ensuring the safety of navigation in border waters, as well as carrying 
out various industrial activities in the continental shelf and the exclusive 
(maritime) economic zone of Ukraine (Sitsinskyi, 2014). 
The subject of Nick Megoran’s research was border and territorial 
disputes between Kyrgyzstan, Uzbekistan, and Tajikistan. The author 
studied the problems of the delimitation of national territories and the 
drawing of borders, as well as the results of the Soviet-era policies that 
continue to have a complex impact on the region (Megoran, 2004).
