1 2  The concept of state sovereignty is somewhat imprecise and there are disagreements about whether certain territories are sovereign. There are currently 194 states that are generally regarded as "fully" sovereign: this includes the 193 member states of the United Nations plus Vatican. Some of these states have under their jurisdiction territories, dependencies, or collectivities that are clearly non-sovereign geographical areas. These territories are generally regarded as being subsumed within the overarching sovereignty of the governing state. For example, the United Kingdom holds sovereignty over the territory of Gibraltar, even though Gibraltar is not considered to be part of the United Kingdom. There are a few territories in the world that are neither clearly sovereign nor clearly subsumed under another state's sovereignty. Often, these territories have declared themselves to be sovereign, but they are either not widely recognized as such or lack some of the necessary conditions for sovereign statehood. In these cases, explanatory footnotes indicate how the territory is treated for the purposes of this list.

Territorial claims in Antarctica have been recognized only between the few countries making claims in the area. Because some of the claims overlap and there is a low number of recognition for these claims, Antarctic territorial claims are not included in this chart when listing countries' neighbouring countries and territories. The specific Antarctic claims are included in this chart, but only in reference to each other.

1 2 3 4 5  In 2008, Kosovo declared independence from Serbia. Although Kosovo's sovereignty has been recognized by about 65 states, it is not a member of the United Nations and Serbia disputes its sovereignty, claiming that Kosovo remains one of its provinces. The dispute has been referred to the International Court of Justice. For purposes of this list, Kosovo is considered to be a sovereign country. If Kosovo is considered part of Serbia, some numbers in the table would be reduced by one (e.g., when a state borders both Serbia and Kosovo). Other numbers would remain the same (e.g., when a state borders Kosovo but not Serbia).

These 198 exclave borders plus the main border give a total of 199 sections of border.

↑  Northern Cyprus declared independence in 1983, shortly after Thổ Nhĩ Kỳ invaded the island in response to a coup d'état by Greek Cypriots that was backed by Hy Lạp. Cyprus disputes the declaration of sovereignty and considers Northern Cyprus to be part of its territory. The United Nations and the European Union also do not recognize the sovereignty of Northern Cyprus. The only sovereign state that recognizes Northern Cyprus's sovereignty is Turkey. Northern Cyprus also lacks some of the indicators of legal sovereignty, relying heavily on Turkey for its continuing existence separate from Cyprus. Because of these factors, Northern Cyprus is not considered a sovereign state for the purposes of this list and is not included in other countries' listings of neighbouring countries and territories.

In Taiwan, the ROC continues to claim sovereignty over all China, including the mainland and Taiwan. The Trung Quốc (PRC), which has governed mainland China since the ROC government retreated, also claims to be the sole representative of all China, including Taiwan. Even though the ROC government in Taiwan has never asserted that Taiwan's sovereignty is separate from that of China's, for many practical purposes Taiwan is treated by other countries and international organizations as a country that is separate from the PRC.
