"We are in a period of transition in the Olympic Movement," ASOIF President Ingmar de Vos said in his speech welcoming IOC President-Elect Kirsty Coventry and paying tribute to IOC President Thomas Bach, at the ASOIF General Assembly.
Also addressing President-Elect Kirsty Coventry, World Athletics President Lord Coe said: "There is a huge opportunity with the new leadership to create the reset around the relationship between the IOC and the IFs, and particularly the review of the revenue generation model.
"We all want the pinnacle of Olympic sport being the pinnacle of the four year summer sporting cycle and we look forward to working with you. You will have the support all the IFs; we stand ready to support you.
IOC President-Elect Kirsty Coventry said: "We would all love to say we hope the next few years are going to be smooth but I'm not sure that's quite going to be the case."
Listing the challenges ahead, she referred to "all the geopolitics we are going to need to navigate, the more and more conflicts that our world is facing, revenue models."
"We won't always agree. We hope we can be respectful enough to disagree... but that's what a family is about. It's how we are going to come together to make sure we have the best Olympic Games and the best platform for generations to come."
Bravely challenge models
With reference to recent "tough discussions" with ASOIF about "event delivery", she said "International federations need to play a greater role."
"It's important to take some time to engage with all of you to fully understand not just want your expectations are, but how we are going to deliver extraordinary Games in LA and Brisbane, and into the future.
"We have to be brave enough to challenge some of the models that we've been doing.
"It's very clear there are two priorities, two pillars: the Olympic Games, and ensuring the Olympic Games is the biggest success for our athletes; and the second one is then building a better world through sport. The first one has to be extremely successful in order to have the second one.
"So we really need to focus on how we are going to ensure together we are going to have incredible Games that will inspire generations and more people across the world."
