Why Facebook Can't Go to China Alone

Tickers in this article: FB RENN TWTR WB

NEW YORK (TheStreet) -- Facebook is already the world's largest social media company, with over 1.2 billion monthly active users (MAUs), and growing. However, if the company is going to enter China and do so to get even bigger, it's probably not going to go it alone.

Bloomberg reported Facebook is set to open a sales office in China this year, as it seeks to work with local advertisers, according to sources with knowledge of the matter.

Facebook could not be immediately reached for comment for this story.

Currently, Facebook is banned in China and though COO Sheryl Sanberg has made inroads in the country, meeting with various Chinese officials, including Cai Mingzhao, the head of China's State Council Information Office.

Should the Mark Zuckerberg-led Facebook enter China officially, it will likely have to do so like almost every other American company, be it in the technology field or not: via a joint venture. Companies like General Motors , Ford  and others have joint ventures with Chinese-based companies, so it stands to reason that Facebook, the largest social network in the world, would likely have to partner with its Chinese counterpart in order to gain access to the country, and its 1.3 billion citizens.

Perhaps Facebook gains entry into China by sharing patents, intellectual property or other methods with Renren or another Chinese social network.

Given the fact that Twitter and Facebook are currently not in China, due to the country's apprehension about social media in general, there are a slew of companies Facebook could partner with. Sina's Weibo , essentially the Chinese version of Twitter, could be a potential partner, with its more than 129 million MAUs.

Weibo went public in the U.S. last month, pricing its IPO at $17 a share, selling 16.8 million American depository shares, at the low end of the expected price range.

Among others, WeChat, owned by Tencent, could be another partner, given Facebook's recent announced acquisition of WeChat-competitor, WhatsApp.
