He is the highest-ranking official to visit the Marshall Islands since President Ma Ying-Jeou took office in May 2008.
The Marshall Islands is one of six nations in the Pacific and 23 globally that have diplomatic ties with Taiwan.
The Taiwan Embassy in Majuro said Ou and his delegation is scheduled to arrive Thursday and leave Saturday.
He will meet with Marshall Islands President Litokwa Tomeing, who survived a vote of no-confidence late last month, and attend official celebrations on Friday, May 1 marking the 30th anniversary of the country’s constitution, its independence day equivalent.
Taiwan is the second largest aid donor to the Marshall Islands after the United States.
Late last week, Taiwan Ambassador Bruce J.D. Linghu delivered a check to Marshall Islands Foreign Minister John Silk for more than $2 million in quarterly development funding assistance.
In addition, the Taiwan government operates and supports agriculture and aquaculture projects, funds a micro-loan scheme, stations health officials at the main hospital and sends two mobile medical teams annually.
