Diabetes Fiji will host youths from Tuvalu, Tonga, Papua New Guinea, Solomon Islands and Vanuatu.
Its project manager Viliame Qio says the first-of-its-kind event will train participants in how to lead diabetes associations and help others with the disease in their countries.
He says part of the conference involves a health camp, where participants will meet with doctors and learn more about food, oral care and eye health.
