__NOTOC__ This is a list of countries and territories by maritime boundaries with other countries and territories. The list encompasses adjacent maritime nations and territories with a special focus on the boundaries or borders which distinguish them. For purposes of this list, "maritime boundary" includes boundaries that are recognized by the United Nations Convention on the Law of the Sea, which includes boundaries of territorial waters, contiguous zones, and exclusive economic zones. However, it does not include lake or river boundaries. "Potential" maritime boundaries are included; that is, the lack of a treaty or other agreement defining the exact location of the maritime boundary does not exclude the boundary from the list. In numbering maritime boundaries, three separate figures are included for each country and territory. The first number is the total number of distinct maritime boundaries that the country or territory shares with other countries and territories. If the country shares two or more maritime boundaries with the same country or territory and the boundaries are unconnected, the boundaries are counted separately. The second number is the total number of distinct countries or territories that the country or territory borders. In this instance, if the country or territory shares two or more maritime boundaries with the same country or territory and the boundaries are unconnected, the boundaries are only counted once. The final number is the total number of unique sovereign states〔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 City. 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.〕 that the country or territory shares a maritime boundary with. Footnotes are provided to provide clarity regarding the status of certain countries and territories. ==See also== * List of political and geographic borders * List of countries and territories by land borders * List of countries and territories by land and maritime borders * List of maritime boundary treaties * List of territorial disputes * Landlocked country 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of countries and territories by maritime boundaries」の詳細全文を読む スポンサード リンク
