What does the flag of the WTO mean?

The five rings are blue, black, red, yellow and green. The top three rings and the bottom two rings are closely linked. According to Coubertin's explanation, the five rings "symbolize the five continents in the world that recognize the Olympic Movement and are ready to participate in the Olympic Games, and the sixth color, white-the background color of the national flag, means that all countries can participate in the games under their own national flags without exception." Later, it was explained that the International Olympic Committee originally adopted blue, black, red, yellow and green as the colors of the five rings because it could represent the colors of the national flags of all countries participating in the International Olympic Committee at that time. Starting from the 7th Olympic Games 1920, the colors of the five rings symbolize five continents: blue for Europe, black for Africa, red for America, yellow for Asia and green for Australia. 1973 The Olympic Forum, the journal of the International Olympic Committee, emphasizes: "The five rings of the emblem and the flag symbolize the unity of the five continents, and athletes from all over the world gather at the Olympic Games in a fair and frank competition and friendly spirit.
