(CNN) - Sarah Palin's speech to investors in China later this month will be closed to the media, organizers of the event confirmed to CNN Monday.
The former Alaska governor is set to address the annual CLSA Investors' Forum September 23, though the group is also declining to reveal the topic of the former GOP vice presidential candidate's closed-door speech.
"We are not disclosing the topic of Sarah Palin's presentation at this point," said Simone Wheeler, head of communications for CLSA.
Wheeler said much of the four-day forum, which includes more than 200 presentations, is closed to the media except for a handful of keynote addresses where the speakers have specifically allowed members of the press to be invited.
Palin, whose lack of foreign policy credentials was criticized by Democrats during the 2008 campaign, apparently was not among those speakers willing to grant members of the media access to her speech.
"For keynote presentations, it is the speaker's decision as to whether or not their sessions are closed. Several of our keynotes this year are not open to media," Wheeler said.
There has been speculation Palin could receive upwards of six figures on the speaking circuit, though the organization is remaining tight-lipped on that matter.
"We never disclose if, or how much, our speakers are remunerated," Wheeler said.
