Linkedln also has a Chinese presence, and would, of course, also like to be the leading professional network in China. But company insiders note that doing business in China is quite different than elsewhere. First there is the question of whether a free-spirited social network can survive government censorship. For instance, both Facebook and Twitter have been banned in China. There is a strong popular sentiment in China to support Chinese companies. Also, the business culture is different in China: for instance, face-to-face meetings are preferred, and doing business with strangers is distrusted. In this sense, online social networks need to focus on facilitating offline connections, something that a site like Meetup in the United States does quite well. Up until now, both Viadeo and Linkedln have been allowed to operate in China. If Viadeo can make inroads with Tianji in China, that may represent the best path to dethroning Linkedln in the professional social network market space.
