Foreign relations of the Cook Islands

The Cook Islands maintains diplomatic relations with various countries and is a member of multilateral organisations.

While the country is in free association with New Zealand, which can act on the Cook Islands' "delegated authority [...] to assist the Cooks Islands" in foreign affairs,[1] the Cook Islands nevertheless enters into treaty obligations and otherwise "interacts with the international community as a sovereign and independent state.

The Repertory of Practice of United Nations Organs records that in 1988 New Zealand declared "that its future participation in international agreements would no longer extend to the Cook Islands..."[2] In 1991 the Cook Islands became a full member of the United Nations Conference on Environment and Development (UNCED) Preparatory Committee and the Intergovernmental Negotiating Committee for a Framework Convention on Climate Change (INC), which the Repertory of Practice describes as "further evidence that the international community had accepted the Cook Islands as a “State” under international law.

"[2] The United Nations Secretariat therefore "recognized the full treaty-making capacity of the Cook Islands" in 1992[2] and the Secretary-General, in his capacity as the depository of multilateral treaties, decided that the Cook Islands could participate in treaties that were open to "all states".
