Twitter China head Kathy Chen leaves company

Twitter Inc executive Kathy Chen, who courted potential Chinese advertisers for the social media platform, announced her departure from the company in a tweet on Saturday. "Now that the Twitter APAC team is working directly with Chinese advertisers, this is the right time for me to leave the company," she wrote. Twitter grew its Greater China advertiser base nearly 400 percent over the past two years, she wrote, making it one of the company's fastest growing revenue markets in Asia Pacific.
