BEIJING  -- Foreign journalists should complain formally if they have any official problems in doing their jobs during the Beijing Olympic Games, senior Chinese leader Li Changchun said on Thursday.

"If you are dissatisfied, you can file your complaint directly to Liu Qi, president of Beijing Organizing Committee for the Games of XXIX Olympiad," Li told reporters. Liu accompanied Li around the media center, one of the three major news centers of the Beijing Games.

Li, a member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee, welcomed all foreign journalists to China for the Olympics, saying, "I hope you could truly and fully cover the event and tell the world a true China."

Li said the center could provide broadcast transmissions around the clock. He promised to ensure the security of transmissions, a major concern of overseas journalists, and asked the staff to strengthen security measures.

Answering a question from an Aljazeera reporter, Li said China was fully capable of ensuring the security of the Games from August 8 to 23.

Juan Rosso of Columbia's Caracol Radio was satisfied with the service at the media center. He told Li that technology here was perfect, convenient and advanced.

"Colombian people need to know more about China as more Colombian entrepreneurs have come to China to invest, or look for options," he said.

Rosso said during the Games their reporting would also focus on China's economy, culture, history, tourism, entertainment and lifestyle.

Li's Thursday visit to the media center was to examine work there so as to ensure domestic and foreign reporters enjoy quality service during the Games.

Andrew Kirillov, Beijing bureau chief of the Russian Itar-Tass News Agency, said the visit to the media center by senior Chinese leader demonstrated the central government's strong support of the Games.

"Our work will be ultimately judged by all reporters," Li said.
