On what basis is the international torch relay route determined?

From the perspective of the torch relay route, there is only one city in North America, South America, Oceania and Africa. It may be that except for the continent hosting the Olympic Games, only one city in other continents can participate in the torch relay. But there are four cities in Europe (not counting Greece), namely Istanbul, Paris, London and St. Petersburg, representing the four countries of Turkey, France, the United Kingdom and Russia. Among them, Turkey is the country at the handover of Europe and Asia, and the United Kingdom is the venue for the next Olympics. , This arrangement makes sense. France and Russia may consider that they are both permanent members of the Security Council and should be allowed to participate, so that all five permanent members participate in the torch relay. There should be many countries in Asia. Kazakhstan represents Central Asia, Oman represents West Asia, Pakistan, and India are all countries bordering China and represent South Asia. The other countries are countries in East Asia and Southeast Asia that are adjacent to China and are home to a large number of people. Chinese. This arrangement of routes should be more reasonable.

As far as I know, for a city to serve as a transfer station for the torch relay, it must also apply to the International Olympic Committee through the host country. The country must be willing and there are conditions.
