Competition at the World Championships, due to conclude on Saturday (August 26), begins with action in the Greco-Roman discipline.

Chunayev and Kim, winner Olympic bronze medals at Rio 2016, are among the headline names in action on the first day of action in the French capital.

The Azeri wrestler will compete in the 71 kilograms category, while London 2012 Olympic 66kg champion Kim will target further success in the 75kg division.

The duo are the top-ranked wrestlers in their respective categories.

Roman Vlasov of Russia and Riza Kayaalp of Turkey, who will enter the event on Tuesday (August 22), are both bidding for their third world Greco-Roman titles.

Vlasov, winner of a second Olympic title at 75kg at Rio 2016, is wrestling at 80kg for the first time.

Kayaalp, who earned a silver medal in the 130kg class at last year's Olympics, is hoping to get back to the gold standard in the first World Championships of the Tokyo 2020 cycle.

Women's freestyle events are due to be held on Wednesday (August 23) andThursday (August 24), before men's freestyle action take place on the following two days.

For the first time since 2002, Japan head into the World Championships women’s freestyle event without multiple champions Saori Yoshida or Kaori Icho – who have amassed 23 world titles and seven Olympic Games gold medals between them in the past 15 years.

Japan's squad still contains four favourites for gold who have an average age of 20 years and six months.

The event will also give Paris the chance to once again show off their credentials in hosting major sporting events prior to the city being officially awarded the 2024 Olympic and Paralympic Games.

The AccorHotels Arena, where competition will take place, is among the venues the French capital plans to use during the Games in seven years.

It is set to stage basketball, judo and wheelchair basketball at the Olympics and Paralympics.

UWW President Nenad Lalovic, also a member of the International Olympic Committee, described the venue as "one of the best arenas" in the world.

"These first Championships of the Olympic cycle are the opportunity to see the future stars of the upcoming Tokyo 2020 Olympic Games," the Serbian said.

"On behalf of UWW, we thank the French Wrestling Federation as well as the City of Paris for the organisation of our 2017 Wrestling World Championships, in one of the greatest arenas in the world and we hope that all visitors will enjoy their stay in Paris and will go back home with unforgettable memories."
