William Quinto, a Belizean businessman of Chinese descent and a supporter of Belize's People's United Party, began lobbying then-Prime Minister George Price via his mutual acquaintance Said Musa for Belize to establish relations with Taiwan in the 1980s.

[1] Then-Taiwanese ambassador to Guatemala Gene Loh came to Belize in May 1984 and met with Quinto and Price to discuss the possibility of establishing relations, but Guatemalan leader Rodolfo Lobos Zamora objected, and after Manuel Esquivel of the Belizean opposition United Democratic Party took power in the election late that year, the plans were put aside.

[2] At that point, Belize only had three overseas missions, in London, Washington DC, and at the United Nations in New York City; Musa, who by then had become Minister of Foreign Affairs, told Quinto that if he did not go to Taipei to fill the position of ambassador, there would be no one else to take the job, and thus he went.

His subordinate, chargé d'affaires Efrain R. Novelo, was promoted to full ambassadorial rank to replace him.

[3] In 2021, Taiwan and Belize signed a mutual assistance treaty that would serve as a framework to legal cooperation between the two countries.
