When asked during a Liberty Media's conference call about the future of the British Grand Prix, Carey replied: "We've said in the past this is a sport that seems to like to negotiate in public".
Vietnam has signed a 10-year deal to stage a street race through the capital of Hanoi.
Commenting on bringing the famous race series to Vietnam Hanoi chairman Nguyen Duc Chung said: "It demonstrates Vietnam's ability, as one of the fastest growing economies in the world to host events on a global scale and attract tourism to the country". "It already feels like we are on race 25 this year, so I don't think that's a good thing". Carey said the decision to hold the race in Hanoi was a part of Formula One's strategy to move into markets where it hopes to groom a new generation of fans - and boost revenues.
"One of the most hard moments of the year was in Russian Federation for me", he had said in Mexico City, referring to a race in which Bottas was asked to move aside to let him win.
Formula One's mixed history in Asia shows that Vietnam will need to steer clear of the problems that plagued other races when it joins the circuit in 2020, experts say.
The race will take place at a new street circuit that winds its way through the city of Hanoi.
"Beyond that we are looking to identify further street races, so this race is a further step in terms of our vision".
"One of the things we have been intensely focused on is extending grand prix racing to iconic cities, in downtown areas, where we can best engage fans", he added.
The race will certainly be more action packed than the Monaco or Singapore Grand Prix's due to the presence of two long straights, with one measuring 1.5 kilometers (0.9 miles).
Bratches envisions more races in cities such as Hanoi and said F1 is carefully considering where to go next based on a number of offers from around the world.
"The US remains a priority, we're engaged with discussions elsewhere in the US so it's not just Miami, and [there's] opportunities, but we think Miami really could be a great signature event for us worldwide, not just in the US".
