Tonga and China are poised to sign a Memorandum of Understanding for the export of squash to the Chinese market later this year.
This comes after an arrangement last year when 23 tonnes of squash was shipped to China for the first time.
The CEO of Agriculture Viliami Manu told Radio Tonga that documentation outlines procedures for farmers such as the amount of fertilisers used, the process of packing and eventual export to China.
Dr Manu said Chinese officials wanted to ensure that the pack house was well-equipped and safe from insects.
The planting of squash for export to China is expected to start next month and Tonga hopes to be able to send about one-thousand tonnes of squash this year.
