The head of the FBI says he is pleased with China's preparation work for ensuring security at the upcoming Beijing Olympic Games in August and the FBI will offer China help against potential threats.

During a three-day visit to Beijing, Robert Mueller, director of the U.S. Federal Bureau of Investigation, was briefed by the police, paramilitary and counterintelligence agencies in charge of security for the August games.

Addressing a press conference in Beijing on Wednesday, Mueller says he is impressed by China's security preparations for the Olympics.

"We were shown the Olympic sites and preparations that have been made and are impressed by the thoroughness of the preparations, the professionalism that has been put in to provide security for the games."

Mueller says the FBI will be continuing to work with their Chinese counterparts in the run-up to the Olympics, adding that his focus was on securing the venues.

At another press conference Wednesday morning, a spokesman from the Chinese Ministry of Public Security gave no details on the FBI head's visit and the Olympic security work, only saying the ministry is working hard to implement measures.

In addition to discussing preparations for the Olympics, the FBI head also spoke with officials from the Ministry of Public Security about other issues of mutual concern.

"Discussing issues of the moment to both of us: terrorism, cyber crime, public corruption - areas such as this in which we share a common goal to defeat those who would do our publics harm."

Mueller says there are a number of areas that both countries could exchange training, views and expertise.

The FBI established an office at the U.S. embassy in Beijing in 2002. China later began posting police officers at its embassy in Washington. Mueller says the mechanism has helped the fast exchange of information.
