China, the final leg for Facebook to take over the world?

Quoting Wikipedia -

"As of May 2016, the only countries to ban access around the clock to the social networking site are China, Iran, and North Korea. However, since the vast majority of North Korean residents do not have access to the internet, in reality China and Iran are the only countries where access to Facebook is actively restricted in a wholesale manner."

China has the largest internet user base in the world, 513 million people compared to 245 million in US, and a large part of the users are active social media users. Hence, we can see why Facebook is desperately (link here and here) trying to win the favor, and approval of the Chinese authorities.

However, even if great firewall of China opens its door to Facebook, it remains to be seen if Mark Zuckerberg and team would be able to replicate their success in the Middle Kingdom - the reason being most young internet-savvy Chinese are now accustomed to the use of the likes of WeChat, RenRen, Weibo.

If the social media giant agrees to strictly censor content delivered to Chinese users, then it would seem pointless for people to ditch their current platforms for Facebook.
