Due to the health situation in Switzerland and in Europe, the Organizing Committee and the European Table Tennis Federation (ETTU) have agreed to postpone the 2021 edition of Top 16 Cup during the second semester, at least after the Tokyo Olympics.

The exact date will be determined by agreement between the city of Montreux (for the availability of the "Salle du Pierrier"), the ETTU and the organizing committee, as well as taking into account the international calendar which has not yet been established.
