The 2021 revision of nautical chart no. 8 by Chile has sparked a maritime boundary dispute with Argentina. This issue arises from Argentina's 2009 submission to the Commission on the Limits of the Continental Shelf for an extended continental shelf and centers on conflicting interpretations of the Treaty of Peace and Friendship of 1984. The treaty delineates the maritime boundary from Points A to F, but Chile’s inclusion of a legal continental shelf southeast of Point F in its updated chart extends beyond Argentina's recognized limits, leading to an overlap with Argentina's extended continental shelf claim. This paper analyzes the legal validity and enforceability of both nations' continental shelf entitlements under UNCLOS and the Treaty of Peace and Friendship, discussing the procedural challenges and potential solutions to the overlapping claims.
