"We recognise that increased trade is not just about more products being exported, it's about an exchange of knowledge, expertise, technology and services, and investment," he told the Development Research Centre Food Security and Food Safety Strategy Summit.
He said New Zealand and China's primary sectors were becoming increasingly interconnected through two-way investment and lengthening supply chains.
"Building our own capacity in isolation is not enough – we need to work with our partners to ensure a stable supply of food for our region," he said.
"Strengthening cooperation is a major focus of New Zealand's and China's 'Comprehensive Strategic Partnership'. We are focussed on consolidating and expanding cooperation in agriculture, including strengthening cooperation in trade, supporting the capability-building of China's dairy sector, and implementing the new Food Supervisory and Traceability Cooperation Programme.
"This has been evidenced by the significant number of cooperation programmes that we have targeted to China's agricultural goals in areas where New Zealand has world class expertise.
"In particular, we have focused our efforts on technical cooperation in dairy, as China seeks to consolidate the recent gains it has made in the productivity and commercialisation of its dairy sector."
