It will be the first summit between Taiwan and its diplomatic allies in the Pacific and it is to become an annual meeting in the future.
The meeting will be hosted by Taiwan's President, Chen Shui-bian, who will make his third Pacific islands trip in two years.
The Marshall Islands has confirmed its attendance, with Solomon Islands, Tuvalu, Kiribati and Nauru also expected to be present.
The two Chinas host countries with which they have diplomatic ties.
