Hugh Pickens writes writes "The Guardian reports that Google has accused the Chinese government of interfering with Gmail. According to the search giant, Chinese customers and advertisers have increasingly been complaining about their Gmail service in the past month and attempts by users to send messages, mark messages as unread and use other services have generated problems for Gmail customers. The announcement follows a blog posting from Google on 11 March in which the firm said it had "noticed some highly targeted and apparently politically motivated attacks against our users. We believe activists may have been a specific target." The search firm is not commenting further on this latest attack, but technology experts said it seemed to show an increasingly high degree of sophistication. "In the wake of what is happening in the Middle East I don't think China wants to be seen making heavy-handed attacks on the internet, that would draw too much attention," says one internet executive who wished to remain anonymous adding making it look like a fault in Google's system was extremely difficult to do and the fact that these attacks appear to come and go makes the attack look "semi-industrial and very, very sophisticated.""
