The deal comes less than six months after Anti-Doping Norway chief executive Anders Solheim called for Oslo to withdraw their financial backing to the Winter X Games due to the lack of World Anti-Doping Agency (WADA) compliant testing at this year’s event in Norway’s capital.

WADA claimed at the time that talks were ongoing with organisers on installing an anti-doping programme for the Games after its director general David Howman warned the lack a compliant testing system programme "sends the wrong message to athletes at a fragile time for clean sport worldwide".

Henning Andersen, who is in charge of the Winter X Games in Norway, said it was "crucial to achieve" the agreement that is now in place.

"We are proud to be promoting anti-doping work in a big event like the X Games Norway," he told TV2, the leading commercial broadcaster in Norway.

Solheim added: "We have history behind us and look ahead.

"This is pioneering work."

Despite the agreement, the City of Oslo’s Vice-Mayor for Culture and Sport has refused to promise that money will be allocated to support it.

"We have always said that the X Games is a terrific event in Oslo," said Rina Mariann Hansen.

"Whether it means that you should get many millions from Oslo's budget, we must come back to."

The Norwegian Ski Federation (NSF) withdrew its cooperation agreement with TV2 in protest at the situation that arose earlier this year.

NSF President Erik Røste described the agreement as "good news" in a text message to TV2 Sport.

"It has been our focus," he wrote.

"The same rules must apply to the X Games as in any other event."

The event in February marked the first time both summer and winter sports were contested internationally at the same X Games event.

As well as male and female snowboard and freestyle skiing big air and superpipe events, male and female street skateboard competitions also took place.
