Background on the JDZ
In the spring of 2001, the governments of São Tomé & Principe and Nigeria reached an agreement over a long-standing maritime border dispute. Under the terms of the agreement, the two established the Joint Development Zone to govern commercial activities within the disputed boundaries.
Oversight of the JDZ
The JDZ is administered by a Joint Development Authority (JDA) which oversees all future exploration and development activities in the JDZ. The remaining claimed territorial waters of São Tomé & Principe are known as the Exclusive Economic Zone (EEZ).
Revenue Split
Revenues derived from the JDZ will be shared 60/40 between the governments of Nigeria and São Tomé & Principe, respectively.
