During a visit to Taichung Veterans General Hospital (TVGH), Waqa said he was grateful for the medical service the hospital has been providing to people in his country for many years.
At the hospital, he was also presented with a gift of 200 doses of dengue fever rapid screening reagent to take back to Nauru, one of Taiwan's diplomatic allies in the Pacific region.
TVGH administrator Hsu Hui-heng, who handed over the reagents, said the hospital has been sending medical teams to Nauru since 2008.
In 2011, under the auspices of the Ministry of Foreign Affairs, a memorandum of understanding was signed between TVGH and Nauru's Ministry of Health and Medical Services, Hsu said.
In addition, through a medical cooperation plan that was implemented in 2014 with Nauru and other Pacific allies, TVGH has been providing medical assistance to Nauru and professional training for its healthcare and medical staff, Hsu said.
Waqa, who arrived in Taiwan on Monday at the head of a 13-member delegation, is on a five-day state visit.
