Hello,

Your interpretation of the Peruvian constitution is not correct, or at least does not match what the government of Peru claims. While Peru indeed has a 200 nm maritime dominion, only the first 12 nm of it is territorial sea.

This is clear from the statements made by Peru during the proceedings at the International Court of Justice during the dispute with Chile. Peru has formally stated that the application of the maritime domain is consistent with UNCLOS maritime zones (i.e. max 12 nm territorial sea, 24 nm contiguous zone, 200 nm EEZ).
