Kailas, an outdoor sports company, and Entre-Prises, who create climbing walls, were already long-term allies of the governing body and have now been joined by four more companies.

DJI, a drone and aerial photography firm, have signed up having previously helped the IFSC produce images at several of its international events.

Extreme sports channel Epic TV is also on board, along with climbing and outdoor shoes company Tenaya.

Completing the group is Luxov, a company which pledges to allow people to enjoy rock climbing in a "friendly and interactive way".

This year is a big one for sport climbing, with the sport hoping to be added to the Olympic programme for Tokyo 2020.

It is one of five sports in contention along with baseball/softball, karate, skateboarding and surfing with the International Olympic Committee (IOC) scheduled to make a decision at its Session this year in Rio de Janeiro.

"We are very honoured to renew our partnerships with Kailas and Entre-Prises," said IFSC marketing and communications director Anne Fuynel. 

"Both companies have been very supportive in our ambition to be part of the Olympic Games and have helped us developing the sport worldwide.

"We are also very pleased to welcome new innovative partners that all share the same values.

"It confirms that our sport is growing fast and gets the support of companies in and out the climbing community.

"Our sport attracts the young generation, the sport presentation has been improved in order to attract a broader audience and deliver an exciting experience.

"All these innovative partners will support us in our quest to reach a new step.”

If climbing is selected by the IOC, bouldering and lead and speed combined will be the two disciplines contested.

A total of 40 climbers would take part in Tokyo in all.
