The foreign ministers of the Gulf Cooperation Council member states and UK Secretary of State James Cleverly have urged Iraq to complete the demarcation of Kuwaiti-Iraqi maritime borders.

In a joint statement released Friday, the officials urged Iraq to respect international agreements, especially regarding the demarcation of Kuwaiti-Iraq borders.

The statement followed a meeting between Cleverly and GCC Secretary-General James Al-Budawi on the sidelines of the 78th session of the UN General Assembly in New York.

“They underlined the importance of Iraq’s commitment to Kuwait’s sovereignty and territorial integrity,” according to a joint statement published on KUNA news agency.

Tensions have been rising between Kuwait and Iraq after the Iraqi Federal Supreme Court earlier this month ruled an agreement regulating navigation in the Khor Abdullah waterway was unconstitutional. The court said the law that ratified the accord should have been approved by two-thirds of Parliament.

Kuwait’s Deputy Foreign Minister Sheikh Jarrah Jaber Al-Ahmad Al-Sabah has discussed with UN officials and Western diplomats the latest Iraqi Supreme Court verdict regarding Khor Abdullah.

Sheikh Jarrah met Thursday the German Minister of State Tobias Lindner, UK Minister of State for the Middle East, North Africa, South Asia and the UN Baron Tariq Ahmad, and EU Deputy Secretary-General Enrique Mora.

The land border between the two was demarcated by the UN in 1993 after Iraq’s invasion of Kuwait, but it did not cover the length of their maritime boundaries, which was left for the two oil producers to resolve.

An agreement between the two nations was reached in 2012 and ratified by each of their legislative bodies in 2013.
