Nauru is to have Taiwan take its medical referrals.
The deal will mean Nauruans will be able to get tertiary level care that is not available at Nauru's hospital.
It will include help for cancer and heart patients.
For a number of years Taiwan has been sending medical specialists to Nauru for short stints.
The island only has rudimentary health facilities and historically there has been a lot of reliance on services in Australia.
