A senior executive for Microsoft has said the firm could pull out of non-democratic countries such as China.
Fred Tipson, senior policy counsel for the computer giant, said concerns over the repressive regime might force it to reconsider its business in China.
"Things are getting bad... and perhaps we have to look again at our presence there," he told a conference in Athens.
"We have to decide if the persecuting of bloggers reaches a point that it's unacceptable to do business there."
"We try to define those levels and the trends are not good there at the moment. It's a moving target."
Earlier in the day, speaking at the Internet Governance Forum, Mr Tipson had defended the work Microsoft was doing in China.
At a session about openness he denied that some big businesses were "colluding" with certain governments.
