China Tightens Controls on Foreign Press
Apparently fearing that unrest could spread to China, the authorities have clamped down on activities by foreigners deemed threatening. “Separately, Beijing officials announced Wednesday that they intended to monitor the movements of millions of residents by means of information transmitted by their cellphones. One official was quoted on a government Web site as saying that the new program would provide “real-time information about a user’s activity.” The project aims to monitor all Beijing residents who use cellphones — about 20 million people — to detect unusually large gatherings. One official said the primary use would be to detect and ease traffic and subway congestion. But Chinese media reports said government officials could use the data to detect and prevent protests.”
