Speaking at a welcoming ceremony outside Taiwan's presidential office, Giammattei said Guatemala and Taiwan were "brotherly countries" and important allies.
Speaking in Spanish, he referred twice to the "Republic of Taiwan", rather than its official name, the Republic of China, generally stylised these days by the government as the Republic of China, Taiwan.
Giammattei, standing next to Taiwan President Tsai Ing-wen, ended his speech with a rousing "long live free Taiwan", receiving a broad smile from Tsai who thanked him in English.
