On 9 January 2017, the Permanent Court of Arbitration issued a trilateral joint statement confirming the termination of the 2006 Treaty on Certain Maritime Arrangements in the Timor Sea (or CMATS) between Timor-Leste and the Government of Australia. This statement was issued on behalf of the Conciliation Commission and the Ministries of Foreign Affairs of the Governments of Timor-Leste and Australia.
In the case of Timor-Leste, the Timorese Parliament adopted on 10 January 2017 the Parliament Resolution nº 01/2017, published on 16 January at the Official Gazette, in which it unilaterally terminated the CMATS between the two countries.
