The deals were "a very positive development" following Mr Yule's first visit to Shangdong Province 18 months ago.
He had returned to China three times since, to support Hawke's Bay exports.
"This province is particularly significant for Hawke's Bay and we are doing lots of trade there."
Next year he expected to sign, on behalf of Hastings, a friendship agreement with Dezhou City in Shangdong Province, which is described as "the solar energy capital of China". It had been suggested Hawke's Bay's sunny weather and long sunshine hours could allow it to become a solar energy hub for Australasia, borrowing expertise from the Chinese city.
Shangdong Province, with its population of about 98 million people, had become a major export destination for Hawke's Bay, he said. The region was exporting more wine there than to any other part of the world.
