Chinese runners finished in first, second and fourth place among the women, and second place among the men, on Sunday (October 20).

But according to the IOF, it was proven that the runners had received illegal assistance from spectators in the terrain, and had markings and small paths prepared for them.

A common protest was handed in by the national teams of Russia, Switzerland, France, Belgium, Poland and Austria, and the jury decided to disqualify all competitors in the Chinese team.

According to the jury decision, their results were to be voided and not included in the results lists, and they would not be allowed to start in yesterday's long-distance competition.

The Chinese appealed the decision to International Military Sports Council (CISM), but the protest and jury decision were upheld.

However, the results are not yet official.

It was initially announced by the World Military Games Organising Committee that the long-distance competition would be cancelled in its entirety, but following negotiations with CISM, it was reinstated in the programme without the participation of the Chinese team.

They will also not start in the final relay competitions tomorrow.

"The Military World Games is an event organised under the jurisdiction of the International Military Sports Council but through a Memorandum of Understanding with IOF, the IOF rules govern the conduct of the event," IOF secretary general Tom Hollowell said.

"The IOF takes the actions of the Chinese team very seriously and is pleased to see that the IOF rules regarding the fairness of competition were enforced by the jury and CISM, and that the best solution was found for those athletes who compete within the regulations of the sport.

"The IOF will be investigating together with CISM how sanctions may be applied to those involved in the improper activities.

"Although the event is not an IOF event, the IOF is investigating if any further actions need to be taken to guarantee the fairness of competition at the upcoming World Cup Final in Guangzhou, China, from October 25 to 29. 

"Military and civilian orienteering in China are completely separated organisationally and the World Cup has been controlled within the structure of the IOF, with restrictions on the access to competition information. 

"There is also time to make changes to stop similar types of cheating. 

"However, the IOF will be debriefing the CISM controllers and making further investigations into the nature of the infractions. 

"If verifiable evidence of any improprieties are found, the IOF will apply any sanctions necessary to guarantee the fairness of the competitions at the World Cup.

"The IOF Council will be meeting in connection with the World Cup final and will, as part of the agenda, discuss how the negative activities at the Military World Games may affect the IOF's support to developing Chinese orienteering and also the Memorandum of Understanding with CISM.

"Finally, the IOF wishes to show its appreciation to the clean athletes and congratulate the medal winners of the long distance at the Military World Games 2019."
