Explanation:

The United Nations Convention on the Law of the Sea, 1982 (UNCLOS) is an international treaty that provides a regulatory framework for the use of the world’s seas and oceans.

• The convention has been ratified by 168 parties, which includes 167 states (164 United Nations (UN) member states plus the UN Observer state Palestine, as well as the Cook Islands and Niue) and the European Union. An additional 14 UN member states have signed, but not ratified the convention.

Exclusive Economic Zone

• According to UNCLOS, the EEZ is an area beyond and adjacent to the territorial sea, subject to the specific legal regime under which the rights and jurisdiction of the coastal State and the rights and freedoms of other States are governed by the relevant provisions of this Convention.
• It is defined as generally extending 200 nautical miles from shore, within which the coastal state has the right to explore and exploit, and the responsibility to conserve and manage, both living and non-living resources.
