Prime Minister John Key said the Chinese government had "rolled out the red carpet" for his visit to China.
Mr Key said that the warm welcome showed there was no ongoing damage to New Zealand's reputation in China as a result of the Fonterra botulism scare.
Speaking to TV One's Q+A while in China, Mr Key said the consequences of another food safety scare could be "absolutely disastrous" for New Zealand. "Because in the end our brand is underpinned on the quality and perception of that quality and safety from consumers."
But he said it was inevitable that there would be future food safety issues, it was a question of how New Zealand responded.
"We produce an awful lot of food, and by definition, from time to time, that food will show up issues that we need to take seriously," he said.
