The announcement was made during the General Assembly at the 56th International Congress and Convention Association (ICCA) Congress, currently taking place in Prague, Czech Republic (12-15 November).
It follows what the association says was the "most competitive bidding exercise" in its history.
A total of eight ICCA destination teams submitted first round bids, from whom three were shortlisted just before IMEX in May 2017: Kaohsiung, Yokohama in Japan, and Cartagena de Indias in Colombia.
The final presentations were made to the board on Saturday (11 November), with the winner being announced by ICCA President Nina Freysen-Pretorius on Sunday (12 November).
Freysen-Pretorius said: "All three presentations were creative, passionate, but also strongly business-focused, each with their own personality, and in any other year, any one of the three could easily have been a worthy winner."
However, it was Kaohsiung, with its compelling story of a city that is re-inventing itself through the power of meetings that stood out.
"Their team designed creative concepts that will help ICCA engage more effectively with Asia-Pacific based associations, and they demonstrated great team cohesion and offered tremendous value for money," added Freysen-Pretorius.
"I have no doubt that 2020 will be a wonderful Congress experience for our entire glbal community. Yokohama and Cartagena should also be congratulated on their extremely professional, impressive bids."
