Explain with Nepal's perspective.

The concept: the EEZ = the zone beyond the territorial sea up to 200 nautical miles from the baselines — the coastal state's functional zone: the sovereign rights for the exploration, exploitation, conservation and management of the natural resources (the waters, the seabed and the subsoil's living-and-non-living resources), the jurisdiction for the artificial islands and installations, the marine scientific research, and the marine environment's protection. The birth (the doctrine's history): the Latin-American 200-mile claims (the patrimonial-sea movement — Chile, Ecuador, Peru's Santiago Declaration line) → the UNCLOS's institutionalisation: the "resource sovereignty" (economic) without the full sovereignty (territorial) — the zones' revolution's centrepiece.
