It appears that both China and the US are also competing for indirect support from New Zealand in regard to China's territorial disputes in the East and South China seas - and that both have won it.
When Mr Key visited President Barack Obama in June, the White House issued a statement saying: "In discussing the need for diplomacy and dialogue to resolve disputes, the two leaders rejected the use of intimidation, coercion and aggression to advance any maritime claims."

And in a statement issued yesterday by Mr Key and President Xi, it said they "reaffirmed their commitment to respecting each other's sovereignty and territorial integrity".
President Xi flew back to Auckland last night where he and his wife, Madam Peng Liyuan, had dinner at Government House with Mr Key and his wife, Bronagh, after being shown around Government House gardens.
But after their formal talks yesterday, Mr Key told reporters he had raised the issue of human rights and Tibet with Mr Xi.
Mr Xi said through an interpreter: "China attaches tremendous importance to protecting and ensuring human rights. Since the founding of the People's Republic of China over the past few decades and more, since we launched reform in opening up China, China's human rights development has registered progress and the progress is there for everyone to see.
"As I often say, for all countries in the world, when it comes to human rights, there is no 'best' as there will always be 'better'.
"The protection and promotion of human rights is an ongoing process that will never stop."
President Xi brought a swag of ministers with him to New Zealand and many of them signed agreements yesterday with their New Zealand counterparts, including one which will make it easy for joint television productions between China and New Zealand to screen to huge audiences in China.
The New Zealand Film Commission yesterday also announced a dedicated $1 million fund to invest in feature film co-productions.
Governor-General Sir Jerry Mateparae hosted a state lunch for the visitors with about 60 Chinese guests and 60 New Zealanders.
One Opposition MP, new Labour leader Andrew Little, attended.
Madam Peng had a doctorate of literature conferred on her by Massey University in Wellington.
Demonstrators, for and against, greeted President Xi outside Government House and Premier House with red banners of hero worship or the yellow protestations of Falun Gong.
President Xi will attend a mayoral forum and a business lunch in Auckland today.
