France's 2030 Winter Olympics bid and Salt Lake City's 2034 proposal will enter into dialogue with the International Olympic Committee, the IOC said on Wednesday.
Bid leaders will intensify talks with the IOC, fleshing out plans and state support, with the Olympic governing body to decide on the 2030 and 2034 hosts at its session in July, 2024.
"The IOC Executive Board today invited the French National Olympic Committee and the United States Olympic and Paralympic Committee into targeted dialogues towards hosting the Olympic and Paralympic Winter Games in the French Alps and the 2034 edition in Salt Lake City-Utah," the IOC said in a statement.
"We will start more detailed discussions with the interested parties," Karl Stoss, head of the IOC's Future Host commission, told a press conference.
"They (cities) have now to do their homework. The decision is not made yet. The work is not finished. But we have another six months to come to a decision," he said.
Salt Lake City had initially wanted to bid for the 2030 Games but dropped plans due to it being too close to the 2028 summer Games in Los Angeles.
France, which will hold the Paris 2024 Summer Olympics, is putting forward a French Alps bid for the 2030 Games.
The country last staged the Winter Games in 1992 in Albertville.
Switzerland and Sweden had also expressed interest in hosting the 2030 Games. Salt Lake City staged the 2002 Winter Olympics.
Switzerland was invited into a "privileged dialogue" for the 2038 winter Games, the IOC said.
