Sino-Niuean relations are relations between China and Niue. Niue has been self-governing in free association with New Zealand since 3 September 1974 when the people endorsed the Constitution in a plebiscite. Niue is fully responsible for its internal affairs. Niue's position concerning its external relations is less clear cut. Section 6 of the Niue Constitution Act provides that: Section 8 elaborates as follows: Niue established diplomatic relations with the People's Republic of China on December 12, 2007. Notwithstanding Niue's constitutional position, the New Zealand government is clear that it does have the capacity and right to establish diplomatic relations with any country, the New Zealand government website stating that: Traditionally, Niue's foreign relations and defence have been regarded as the responsibility of New Zealand, which has full diplomatic relations with China. Importantly, it is a requirement of Niue's constitution that in such matters," consultation between the Prime Minister of New Zealand and the Premier of Niue" must take place and it is not clear that such consultation did, in fact, take place before Niue purported to establish diplomatic relations with China. As such, Niue's authorities may have acted outside the powers conferred on them under Niue's constitution. Another notable matter is that the Joint Communique signed by Niue and China is different in its treatment of the Taiwan question from that agreed by New Zealand and China. New Zealand "acknowledged" China's position on Taiwan but has never expressly agreed with it, but Niue "recognizes that there is only one China in the world, the Government of the People's Republic of China is the sole legal government representing the whole of China and Taiwan is an inalienable part of the territory of China." Critics have asked whether Niueans can continue to benefit from free association with New Zealand and yet disregard New Zealand's advice and establish an independent foreign policy. On 18 October 2008, Zhang Limin, China's first ambassador to Niue, presented his credentials to Niue Prime Minister Toke Talagi in the capital of Alofi. His credentials were accepted by the Niuean Premier. Mr. Zhang is also China's ambassador to New Zealand where he is based. In July 2009, Talagi stated that, if development aid were not forthcoming from New Zealand, he would request aid from China instead. China's opening of diplomatic relations with Niue may be seen within the wider context of China's relations with the Pacific region. Every independent country in Oceania currently maintains diplomatic and economic relations either with the People's Republic of China or with the Republic of China.
