During the negotiations over the Greater Sunrise that led to the CMATS treaty, Timorese representatives claimed that Timor-Leste "owned" Greater Sunrise under international law.
For instance, Prime Minister Mari Alkatiri argued early in CMATS debates that Timor-Leste's stance was not about money but about sovereignty, reflecting a belief that the symbolic dimensions of the dispute would generate more sympathy than if this were merely a dispute over natural resources.
On the one hand, joint development areas created by treaties such as CMATS are an act of sovereign decision-making.

CMATS assigns some oil revenues to Timor-Leste, and improves on previous Australian offers.
The East Timorese watchdog organization La'o Hamutuk (Timor-Leste Institute for Reconstruction Monitoring and Analysis) called CMATS "unjust." "It does not satisfy Timor-Leste's claim for sovereignty or our people's right to all the resources in our half of the Timor Sea," charges La'o Hamutuk.
The CMATS Treaty requires ratification of the framework of the Greater Sunrise agreement, with the revenues divided 50-50.
As in 2003, Australia played hardball to get Timor-Leste to sign the CMATS Treaty, delaying approval of laws necessary for a bidding round on new oil exploration contracts in a joint development area until Timor-Leste had signed CMATS.
