3 Many countries, such as Norway and the United Kingdom, still maintain their ADIZs because of concern over a possible return of tensions. Alternatively, some countries, such as India and Pakistan, have retained their ADIZs because of new regional tensions.

The handbook also includes the right to test and fire weapons, but this right would appear to be tempered by the Article 58 requirement to give due regard to the coastal state’s interests in the EEZ, inasmuch as live weapons testing could interfere with fishing activities, fragile species (e.g., marine mammals, coral, etc.), shipping lanes, or offshore installations.

Oxman, The Third United Nations Conference on the Law of the Sea: The 1977 New York Session, 72 AJIL 57, 59 n.8 (1978)Google Scholar. Oxman, a U.S. representative at the New York session of the conference, writes that Article 58 was intended to preserve full high seas freedoms in the EEZ, not merely passage rights, although “[t]here was no disagreement that certain new coastal state rights specified in the Convention (e.g., pollution enforcement rights) would affect these freedoms or that these freedoms must be exercised in the economic zone with due regard to the rights and duties of the coastal state under the Convention.” Id. at 69 n.44.

32 In 1990 thirteen states claimed a 200–nautical–mile territorial sea: Argentina, Benin, Brazil, the Republic of the Congo, Ecuador, El Salvador, Liberia, Nicaragua, Panama, Peru, Sierra Leone, Somalia, and Uruguay. U.S. Dep’t of Defense, Maritime Claims Reference Manual2–3 (July 1990). By 2008, only seven states continued to retain laws claiming a 200–nautical–mile territorial sea: Benin, the Republic of the Congo, Ecuador, Liberia, Nicaragua, Peru, and Somalia. Id. (June 2008), available at http://www.dtic.mil/whs/directives/corres/html/20051m.htm [hereinafter MCRM]. However, since five of these states are party to UNCLOS (Benin (1997), Congo (2008), Liberia (2008), Nicaragua (2000), and Somalia (1989)), which through Article 3 explicitly limits the territorial sea to 12 nautical miles, the number of states currently claiming a 200–nautical–mile territorial sea may in fact be only two (Ecuador and Peru). A representative of the Benin Foreign Ministry, for instance, provided an informal statement to the U.S. Department of State in 1998 that Benin now recognizes a 12–nautical–mile territorial sea, although Benin’s Decree 76 —92 of April 1976 claiming a 200–nautical–mile territorial sea remains listed on the UN Web site as that state’s official claim. MCRM, supra; United Nations, Maritime Space: Maritime Zones and Maritime Delimitation, available at http://www.un.org/Depts/los/LEGISLATIONANDTREATIES/. Additionally, although Peru claimed “exclusive jurisdiction and sovereignty” over a 200–nautical–mile maritime zone, in practice the precise nature of its claim is unclear. Declaration on the Maritime Zone, Aug. 18, 1952, 1006 UNTS 323, available at http://www.un.org/Depts/los/LEGISLATIONANDTREATIES/. Peru’s claim may be affected by its litigation with Chile pending before the International Court of Justice, in which Peru asked the Court to “adjudge and declare that Peru possesses exclusive sovereign rights” in the area of dispute.

47 The United States routinely protests coastal state assertions of authority that are inconsistent with UNCLOS through the Freedom of Navigation Program, which involves diplomatic representations, operational assertions, and bilateral and multilateral consultations with other governments to promote consistency of state practice regarding international law of the sea.

As early as 1940, the United States established zones in the airspace over the Atlantic out of concern for the possible spread of European conflict. On September 5, 1939, President Roosevelt issued a Neutrality Proclamation that ordered the U.S. Navy to begin neutrality patrols in the Atlantic to report and track any belligerent air, surface, or subsurface contacts approaching the Atlantic coast of the United States or the West Indies. The patrols operated between north latitude 42°30’ and 19°, east to longitude 65°. William, E. Scarborough, To Keep Us out of World War II?

56 In addition to the clarification in 14 C.F.R. §99.9(a) that the paragraph applies only to civil aircraft, some additional hints exist within FAA guidance that the U.S. government does accept that state aircraft are exempt from the regulations. For instance, the International Flight Information Manual, after specifying the requirements for air traffic control of aircraft within an ADIZ, states that aircraft flying outside such control are “subject to interception for positive identification when entering an ADIZ.” FAA Flight Manual, supra note 4, National Security, para, f. Moreover, detailed interception procedures are published, implying a recognition that certain aircraft will not comply with FAA regulations. FAA, Aeronautical Information Manual, supra note 51, para. 5–6–2.

61 DoDI 4540.01, supra note 15, para. 6.4, instructing U.S. military pilots on the proper procedures for operations in another country’s ADIZ, states: “U.S. military aircraft penetrating a foreign ADIZ on a flight plan or intending to penetrate the sovereign airspace of the ADIZ country [must follow specified procedures]. Military aircraft transiting through a foreign ADIZ without intending to penetrate foreign sovereign airspace are not required to follow these procedures.” See also U.S. Air Force, Judge Advocate General’s Dep’t, Air Force Operations and the Law: A Guide for Air and Space Forces 13 (2002)Google Scholar; Poulantzas, supra note 25, at 345.

62 France declared an exclusion zone in the airspace over the high seas off the coast of Algeria in the 1950s and 1960s, which also provoked a strong international reaction when French interceptors forced a Moroccan aircraft to land and attempted to interfere with a Soviet aircraft carrying President Leonid Brezhnev.

It should be noted that the Soviets attempted to claim that the aircraft was within Soviet territorial airspace at the time it was attacked, but the assertion apparently lacked much credibility, since a U.S.–proposed resolution in the UN Security Council calling for a fact–finding investigation had to be vetoed by the USSR to keep it from passing.

Indeed, as recently as September 19, 2007, Chinese television reported that a Chinese Jian–8 fighter aircraft had intercepted a U.S. EP–3 reconnaissance plane flying approximately five hundred feet above the South China Sea, and that increased Chinese intercepts of EP–3 flights over the East China Sea had occurred in advance of a major military exercise in China’s Fujian Province across the strait from Taiwan.

100 See, e.g., Xue & Xiong, supra note 2, at 38 (opining that a Chinese ADIZ is necessary to prevent attempts by the United States “to pilfer Chinese military intelligence in the service of its shameful objectives of interfering in Chinese domestic politics and undermining Chinese territorial sovereignty”).

Open Source Center). Indeed, even before China joined the Law of the Sea Convention, it saw development of the EEZ as a strategy to end the “superpowers’ ‘maritime hegemonism’ and imperialism.” Song, Yann–huei Billy, China’s Ocean Policy: EEZ and Marine Fisheries, 29 Asian Surv. 983, 984 (1989)CrossRefGoogle Scholar.

102 In their private capacity, PLA law of the sea experts concede that an international right to maneuver through another state’s EEZ might be permitted in a manner reflective of the innocent passage regime in territorial waters, but that even this must not be abused. E.g., Remarks by a senior PLA officer at U.S. Pacific Command, Conference on Military Operations and International Law, Singapore (Apr. 15, 2008) (based on author’s notes). Presumably, from this perspective any international military activities other than mere passage would be prohibited in and above the EEZ. Such restrictions, of course, were never intended by the UNCLOS negotiators. Oxman, supra note 20, at 810.

104 Italy established and patrolled an ADIZ off its Adriatic Coast during the 1990s and early 2000s because of the potential spread of the conflict in the former Yugoslavia. See, e.g., Steve, Davies, F–15C Eagle Units in Combat 80 (2005)Google Scholar. ADIZs are also currently maintained by Japan, South Korea, and Taiwan.
