China's highest ranking woman politician, Liu Yandong, ended a two-day visit to New Zealand, marking the 40th anniversary of diplomatic relations between the two countries which formally occurs on December 22.
She was hosted to a ministerial dinner last night at Premier House in Wellington.
China had been considering hosting Mr Key for a visit this month to mark the 40th anniversary but that is now expected to take place next year after the new leadership has settled in.
Yesterday Madam Liu met with Education Minister Hekia Parata and Science and Innovation Minister Steven Joyce.
Mr Joyce and Chinese deputy minister of Science and Technology Wang Zhigang signed a declaration supporting science and technology links.
