A group of Google's advertising partners in China have called on the internet firm to provide some clarity around what it plans to do with its local operations.
The 27-strong group said in a letter that they have waited weeks in "profound pain" since Google announced in January it may withdraw from China, or at least close its search operations.
The announcement follows Google's revelation that the firm had been among at least 20 big companies targeted by China-based hacking attacks.
The Chinese advertising partners are demanding to know how they will be compensated for declines in business because of uncertainty over the future of Google in China, according to the Wall Street Journal.
The letter says the companies have watched their business decline and worry they will be forced out of business if Google withdraws.
Google has acknowledged receipt of the letter and said it is under review, but it has not yet made any official comment on the matter.
The internet firm has also given no indication of the progress or outcome of talks begun in January with Chinese authorities about continuing Google's search operations without censorship.
