China overtook Australia to become New Zealand's largest trading partner last year as surging Chinese dairy demand pushed annual exports to $9.96 billion, compared with $6.86 billion in 2012. Imports reached $8.26 billion, up from $7.71 billion a year earlier, taking two-way trade (which is projected to reach $20 billion by 2015) to $18.22 billion.
Wang said bilateral relations between the two countries were "very much in good shape", despite the various difficulties of 2013, such as Fonterra's botulism fiasco in August and the DCD event in January, when traces of the nitrate inhibitor used on farmland turned up in New Zealand milk products.
"I think it's inevitable that something could erupt because we have a huge volume of trade and great numbers of [Chinese] visitors here," he said. "The way we dealt with that [botulism false alarm] problem showed that we are very much in deep trust."
Wang, who was born in China's northeastern Jilin province, which borders North Korea, said his Government was "reviewing the progress" of the free trade agreement it signed with New Zealand in 2008.
"It's our intention to update this FTA," he said. "I think this will give us a lot of opportunities."
