The company, part of the Adidas Group, said it was likely to shelve plans to set up a corporate hospitality venue at the games this August -- normally a key element of its marketing campaign, where the media, guests and athletes can mix.
The company would not discuss the details of the problems it had encountered, but said it was "looking at other ways" to represent the Reebok brand and give the media access to athletes during the event, which runs from August 8 to 24.
A Reebok spokeswoman said: "The media have access to all the athletes through the official channels.
"In the past at these events we've always tried to service media with additional access."
Reebok is running a major campaign in China ahead of the Olympics, fronted by the Houston Rockets basketball star Yao Ming.
News of the logistical difficulties encountered by the firm comes after its parent company, Adidas, faced calls from some shareholders to withdraw its sponsorship of the games as a sign of protest against China's human rights record.
The German sportswear manufacturer, which bought Reebok in 2005, is a "tier two" sponsor of the Beijing games -- allowing it to display the Olympic logo in its advertising campaigns in China.
In a speech to investors earlier this week, Adidas Group chief executive Herbert Hainer said the firm had received "many letters" from people judging it harshly because of its presence, but insisted it was not the firm's job to be drawn into political issues.
Herbert Hainer, Adidas chief executive, told investors: "We will not be held morally responsible for a situation which we did not create and for which we are not answerable.
"Adidas is not a political company, nor am I a politician."
