I highly doubt there is a &quot;lack of competition&quot; in China. For each and every one of those &quot;Facebook, Messenger, Instagram, Twitter, Snapchat, Youtube, Gmail, Dropbox, Vimeo, SoundCloud&quot; you mentioned, there are a hundred similar companies.<p>In fact, I&#x27;d argue that competition is rife and more ruthless in China than in Silicon Valley. The moment you have a good idea, ten companies will appear the next day hot on your heels. Even if the American stalwarts were to enter the Chinese market, who&#x27;s to say they won&#x27;t be crushed by Chinese competition?
