Google's Chinese customers are demanding clarity
Firms in China that sell advertising on Google are demanding clarity about the company's plans in the region.
A letter from 27 Google-authorised sales representatives was posted on the website of Chinese state-run television.
The letter issues compensation demands for investors, employees and clients.
The warning comes after Google indicated it may close its Google.cn site following concerns that it was being hacked by government agents.
Google and China have not disclosed progress in any talks between them, and Google's clients in the region say that the uncertainty has been going on for too long.
"We see a constant stream of information but cannot predict the future, we see business sliding, but there is nothing we can do," says the letter, which was also posted on a website affiliated with China's central television. "We are waiting now in incomparable pain and disquiet."
The letter spells out demands for redress for investors, employees and clients.
Google has received the letter and is reviewing it, company spokeswoman Jill Hazelbaker said.
