The Daily Telegraph adds more details to the Ai Weiwei email surveillance story:

Mr Ai, who is also a vociferous activist, said he had no proof that the Chinese government had been behind the hacking attempt.

Teng Biao, a law professor at the University of Political Science and Law in Beijing and a human rights lawyer, said his emails had been hacked into in 2007. “Many of my friends told me they received entrapment emails from the email address I was using at the time: against.teng@gmail.com,” he wrote on his blog.

The email subjects were things like ’inside story’, ’contribute an article’ or ’democratic principles’ and had an attachment containing a virus,” he added.

He also said that public security officers had monitored the content of his emails. “Last March, I sent a research project in my email and shortly afterwards the public security officials summoned me for a cup of tea and warned me not to do the research,” he explained.

“At the end of last year, I received an email invitation to a human rights conference in Ireland. Two weeks later, our university officials came to me and said that the heads of the university had heard I planned to visit Ireland and that it was better not to go,” he said.

He added that in two other cases he had innocently asked public security officials: “How did you know that? I have not told anyone” and was told: “Who do you think we are?”
