'The giveaway of 8 American Alaskan islands and vast resource-rich seabeds to the Russians is underway by the U.S. State Department in the guise of an agreement on a maritime boundary between Alaska and Siberia.
In the mid-1970s countries adopted the concept of exclusive economic zones (EEZ) and fishery conservation zones extending 200 nautical miles from their coastlines. If two countries are within 400 miles of each other, they need to negotiate a division of the seabeds by a "maritime boundary". It is usually some variation of an equidistant line between the two coastlines. For the U.S. this has been necessary vis-a-vis Canada, Mexico, Cuba, Russia, among others.'
