Economic incentives? China is a major trading partner for NZ at least.

    China overtook the United States at the end of 2008
    to become New Zealand's second largest trading partner,
    with bilateral trade amounting to $9.4 billion in the
    year ended December 2009.

It's better to use the percentage to put it in perspective.

China makes up 9.1% of New Zealand exports.
