What is the maximum distance of the Exclusive Economic Zone (EEZ) from the territorial baseline?

The Exclusive Economic Zone (EEZ) extends up to 200 nautical miles from the territorial baseline of a coastal state. This concept is outlined in the United Nations Convention on the Law of the Sea (UNCLOS), which was established to define the rights and responsibilities of nations regarding the use of the world's oceans.

Within the EEZ, the coastal state has special rights regarding the exploration and use of marine resources, including fish and energy resources, as well as jurisdiction over economic activities. This zone is distinct from territorial waters, which typically extend only 12 nautical miles from the baseline. The EEZ allows for greater economic exploration and exploitation while still recognizing the coastal state's jurisdictional rights.

Other distances mentioned do not correctly define the EEZ; 150 nautical miles would fall short of the established limit, while 300 and 400 nautical miles exceed the internationally recognized EEZ boundary. Thus, the 200 nautical miles designation is the correct and authoritative limit for an EEZ.
