state, although foreign ships (military and civilian) are allowed innocent passage through it, or transit passage for straits; this sovereignty also extends to the airspace over and seabed below. As a result of UNCLOS, states exercise a similar degree of control over its territorial sea as over land territory and may thus utilise coast guard and naval patrols to enforce border control measures provided they do not prevent innocent or transit passage. Contiguous zone: A state's contiguous zone is a band of water extending farther from the outer edge of the territorial sea to up to from the baseline, within which a state can implement limited border control measures for the purpose of preventing or punishing "infringement of its customs, fiscal, immigration or sanitary laws and regulations within its territory or territorial sea". This will typically be wide, but could be more (if a state has chosen to claim a territorial sea of less than 22 kilometres), or less, if it would otherwise overlap another state's contiguous zone. However, unlike the territorial sea, there is no standard rule for resolving such conflicts and the states in question must negotiate their own compromise. America invoked a contiguous zone out to 44 kilometres from the baseline on 29 September 1999. Exclusive economic zone: An exclusive economic zone extends from the baseline to a maximum of . A coastal nation has control of all economic resources within its exclusive economic zone, including fishing, mining, oil exploration, and any pollution of those resources. However, it cannot prohibit passage or loitering above, on, or under the surface of the sea that is in compliance with the laws and regulations adopted by the coastal State in accordance with the provisions of the UN Convention, within that portion of its exclusive economic zone beyond its territorial sea. The only authority a state has over its EEZ is therefore its ability to regulate the extraction or spoliation of resources contained therein and border control measures implemented to this effect focus on the suppression of unauthorised commercial activity. Vessels not complying with a state's maritime policies may be subject to ship arrest and enforcement action by the state's authorities. Maritime border control measures are controversial in the context of international trade disputes, as was the case following France's detention of British fishermen in October 2021 in the aftermath of Brexit or when the Indonesian navy detained the crew of
