"You and I were just talking on the way importance of the dairy industry, the beef industry, also a sheep industry and a growing horse industry as well.

Partnerships signed included those between NZX and Bank of China, Huawei and Spark, Air New Zealand and Air China, and Airways Corporation of New Zealand and KuangChi Science and Shanghai Pengxin Group - on a project to develop balloon technology for an area 20-100 km from the earth's surface to facilitate telecommunications at a fraction of the cost of satellites.
Following the ceremony, Mr Joyce described it as a "good range of partnerships across a range of industries".
"They're all very important and it's great to see some of the Maori involvement in some of these partnerships well."
Many of the agreements had been underway for some time and Mr Xi's visit proved a strong motivator for getting them across the line, Mr Joyce said.
"That's one of the ways that these visits work actually, is that everybody rushes to get everything finished, which is good because it gets a bit more impetus."
Mr Guy said yesterday's time with the President facilitated a number of government-to-government agreements, "today it's about business".
"All of them have some significance for not only the primary sector, but also IT as well.
"We tell the food, fibre and beverage story extremely well, what we don't tell well is the importance of information and technology and also processing facilities.
"We lead the world in that and that's where we've got an opportunity - to help the viability of their farmers, but also their processes.
"This is very much a two-way relationship."
