Mark Zuckerberg is believed to be keen on Facebook moving into China.
Facebook could block content in some countries, a Washington lobbyist for the company has said, adding that it has faced uncomfortable positions over - too much, maybe, free speech.
Facebook is reportedly negotiating with Chinese partners to launch the social network in China, where it is currently blocked from use.
Expanding into China requires abiding by Chinese laws, which require web companies to censor everything from search results to status updates.
'We're allowing too much, maybe, free speech,' says Washington lobbyist for company.
The comments come amid increasing speculation that the company plans to enter the Chinese market, probably in collaboration with a local partner.
