Beijing Olympic organisers are insisting they are providing full internet access to the media during the Games.
BOCOG spokesman Sun Weide said he was sure media did not have problems accessing the internet at the Games' Main Press Centre (MPC).
Asked why media could not access websites relating to the Falun Gong movement, he said it was an "evil cult" outlawed by the Chinese government.
"As I said, we would be providing full access to the internet to facilitate your reporting during the Olympic Games so that your reporting job during the Olympic Games would not be affected in any way," he told reporters today.
"I am sure you don't have any problems in accessing the internet.
"The use of the internet in the MPC follows the rules and regulations of the IOC."
Earlier today Sun said that journalists would not be able to access information or websites connected to the Falun Gong spiritual movement.
Other sites were also unavailable to journalists, he said, without specifying which.
Sun later said the Chinese government had promised "convenient and sufficient" access to media during the Olympic Games.
He refused to say whether journalists would be able to access non-Games related websites, such as those regarding Falun Gong or Amnesty International reports about China.
Asked what was negotiated with the IOC, he said: "During the Beijing Olympic Games, we will provide international reporters with convenient and sufficient access, so that their reporting of the Beijing Olympic Games will not be affected."
"We have no specific information on (access to) some of the websites you mention.
"I think I have made it very, very clear."
Journalists from Australia and elsewhere have complained to Australian International Olympic Committee (IOC) member Kevan Gosper about internet speeds and blocked access to certain websites.
Gosper said he would speak to the Chinese side about the issue.
"I have heard that there are some limitations on access," said Gosper, chairman of the IOC's press commission.
"I will speak with the Chinese authorities to advise them of the restraints and to see what their reaction is."
IOC executive director Gilbert Felli took up the issue with Games organisers yesterday.
However Chinese Foreign Ministry spokesman Liu Jianchao said China had its own management standards for the internet.
Australian Olympic boss John Coates said he was disappointed China was censoring the internet during the Olympics.
"It certainly is disappointing ... I think it's a matter that the IOC will take seriously," Coates said, adding that he was surprised by the development.
Coates, who is also a member of the IOC, said internet freedom was part of China's undertaking for the Games.
"It's a key plank so something that the IOC will take very serious I am sure," he told reporters.
"I don't remember the exact commitments that were given, but that is important, freedom of the press particularly, and full transparency, particularly during Games time, and so I think it is a matter that the IOC will take seriously.
"What they can do about it, I don't know.
"It's one of those things I'm not sure you can do anything about, but we'll see."
