Nauru is one of Taiwan's four remaining Pacific allies after Solomon Islands and Kiribati cut ties last week in favour of China.
Tuvalu, the Marshall Islands and Palau have all since re-affirmed links with Taiwan, as did Nauru's president, Lionel Aingimea, on Thursday.
"Taiwan has been a good partner and has worked closely with us in many sectors that have brought great benefits to the people of Nauru," Mr Aingimea said.
