Latin America territorial-resource sovereignty claims

Latin American states asserting or legislating domestic sovereignty over contested territories whose primary economic significance is hydrocarbon or mineral endowment. The cluster captures cases where the territorial claim is inseparable from the resource question — Venezuela's Essequibo assertion (Stabroek offshore oil), Nicaragua's Caribbean maritime claims, and analogous instruments. Distinct from the EM resource nationalism theme (which covers export bans for value-add) and the Venezuela sanctions-countermeasure architecture (which covers Venezuela's anti-sanctions legal corpus): this theme is about territorial-jurisdiction instruments whose material effect is to threaten or invalidate foreign energy concessions granted by a neighbouring sovereign.
