Re: Japan breaks China's stranglehold on rare metals with sea-mud bona
I have no concrete basis, I assume if the deposit is found in international waters then the finder should have the right to extract it. But from the map shown of the deposits the deep sea mud are found in the waters around Hawaii and Tahiti which are respectively part of American and French territories. And if those deep sea muds do not fall completely within the territorial waters of those countries I think most of those areas will fall at least on their 200-mile Exclusive Economic Zones. Although there will be a conundrum with the US since at to now it has not yet ratified the UNCLOS.
If it is within the EEZ then yes I believe the nation has the right to extract. But just look at the pic certainly a vast area is outside the EEZ in the case of Hawaii (the US) and a good deal is outside for French Polynesia too.
Lets do some rough calculations:
EEZ = 200 n mi = 1.852*200 = r
Assume Hawaii and Tahiti (?) to be points.
=> Area of EEZ = 3.14 * sq(r) = 431014 sq. km = roughly 1/20 th of 8.8 million sq. km (as mentioned in fig.)
Now suppose finders have the right to extract then, did University of Tokyo just hit jackpot ?
EDIT: Just did some searching and total EEZ of Hawaii is around 2.47 million sq. km (it seems EEZ can be extended in some cases and also the 'point' assumption is not a very good one
) but still some 70% lies outside the EEZ.
