BEIJING — The International Olympic Committee was accused of backtracking on its promises of press freedoms Saturday and some Internet sites remained blocked less than a week before the Beijing Games kick off with opening ceremonies.

Under pressure from the IOC, Chinese organizers unblocked some sites at the main press center and media venues on Friday, but others remained censored for journalists covering the Summer Games.

"The IOC has always been very clear to say: We would like the fullest access possible so that you and your colleagues can do your job," IOC spokeswoman Giselle Davies said. "That's clear for us. It's been clearly communicated in a number of meetings with organizers and the authorities. They have given many pledges that that will be delivered."

One reporter quoted IOC president Jacques Rogge as saying "foreign media will be able to report freely and publish their work freely in China. There will be no censorship on the Internet."

Davies suggested that Rogge, who is Belgian, may have not been completely precise when he spoke because he was using English, which is not his native tongue.

"There's been no change in the IOC's position," Davies said. "Again, I think we are trying to hang on every single word often spoken by people whose mother tongue isn't English. Let me be clear again: The IOC would like to see open access for the media to be able to do their job."

Numerous times over the last several years, Chinese officials and high-ranking IOC members said there would be no censorship on the Internet for accredited journalists covering the games.

Chinese authorities regularly block sites used by its citizens. However, they have repeatedly said reporting would be "free and unfettered."

In 2001, when China won the right to host the games, Wang Wei, the organizing committee's executive vice president, was widely quoted as saying, "We will give the media complete freedom to report when they come to China."

A check by The Associated Press on Saturday showed many sites the Chinese government dislikes — for example, the spiritual movement Falun Gong — were blocked. The sites being blocked seem to change daily, although certain key words always draw blank screens. Sites that host thousands of blogs are also routinely blocked.

Typing in "Tiananmen Square Massacre" yielded a site, but all the photographs on the site were blocked.

Kevan Gosper, head of the IOC's press commission, has acknowledged that full access may not be possible with the games taking part in a "communist society."

"I guess there will be some debate as we move toward the games if there are sites that may or may not be open," Gosper said. "And the line between what could be considered as a national interest issue might be a bit blurred. But we'll work on it and we will deal with any potential grievances."

Meantime, some TV officials have complained about limited live access to Tiananmen Square, red-tape rules that hinder the movement of cameras and reporters and the critical allocation of broadcast frequencies.

"We are continuing to work to have the organizers deliver what has been pledged, what has been outlined," Davies said. "And they have also assured us of this."
