Twitter has hired Kathy Chen as its managing director for China. Twitter is blocked in China, but this has not deterred the social network. It insists that it can still make money in China by attracting Chinese celebrities and companies that want to reach an international audience. The social network has seen strong growth in China, with the number of Chinese advertisers using Twitter to target overseas markets having increased by 340% in the last year. With the recruitment of Ms. Chen, Twitter hopes that it will be able to attract even more companies that want to advertise on Twitter to reach potential customers overseas. Ms. Chen has previous experience in a similar position with Microsoft, where she was the general manager for China and helped to create strategic links between Chinese and American companies.
