Foreign internet companies are facing a critical choice between giving in to Beijing's media censorship or risking the loss of Net users, according to a prominent mainland blogger. Zhao Jing whose popular blog was shut down by Microsoft last month under central government pressure, said international internet companies should consider the negative impact on mainland internet users if they surrendered to Beijing's media suppression. 'Internet companies have greatly helped to encourage the free exchange of information and the freedom of communication in China. They've been very helpful to mainland Net users,' said Mr Zhao, a research assistant in the Beijing bureau of The New York Times. 'But now is a critical moment for them, as they must choose between further pursuing their positive contributions or going the opposite way. If they choose the second option, this would be a disaster for mainland netizens ... and they will lose a large number of users.' The blog posted by Mr Zhao - also known by the pen-name Michael Anti - was once regarded as one of the mainland's true sources of information by China's online population. It was closed down after he posted articles criticising the firing of top editors at the Beijing News. Mr Zhao said several MSN blogs kept by mainland journalists had been blocked to Chinese internet users, but were still accessible through a proxy server and in other places, including in Hong Kong . 'This is a 'localised' approach adopted by Microsoft. It is not erasing blogs, as it did to me, but just blocking them on the mainland,' he said. Regarding Yahoo's statement, he said: 'Actions speak louder than words. Nobody cares [about the Yahoo statement on Monday], we want real action.'
