The main goal of World Expos, formally known as International Registered Exhibitions, is to find responses to universal challenges of today.

"The World Cup helps us a lot. Earlier, when we met representatives of voting countries, a significant part of our discussions was aimed at convincing them in our capacity to host such a major event," said Chernov.

"Now we can skip that part and simply say: 'We have held the FIFA World Cup. We can [host the Expo 2025]'. And no one will have doubts about Russia," he added.

The bidding committee head added that the World Cup was a model for the Expo that would be visited by even greater number of people from all over the world.

"We already know that welcoming such an amount of people is a difficult task, but it is absolutely real. We have already learned how to implement such difficult projects, and it is a very serious argument in our favor," he said.

Russia's Yekaterinburg — one of the World Cup host cities — Japan's Osaka and the Azerbaijani capital of Baku are the candidates to host the Expo 2025.

The next World Expo will take place in Dubai in the United Arab Emirates, between 20 October, 2020 and 10 April, 2021.
