The trend of Twitter's corporate executives leaving the company continues. Adam Messinger and Adam Bain, CTO and COO of Twitter respectively, were among those executives who left the company recently and now the business head for China has also bid a goodbye.

Kathy Chen, the managing director of Twitter for China, joined Twitter seven months ago but left after the company restructured in Asia. The restructuring was part of a company-wide change that included laying off nine percent of Twitter's staff and the resignation of a significant number of high executives.

Kathy Chen, who had no experience in using the social blogging site before joining Twitter, sparked controversy when she joined the company last April 2016, as its first managing director for greater China. Her employment records and evident government connections raised concerns in China.

Aside from famous names like Cisco and Microsoft, Quartz reported that Kathy Chen had spent seven years researching missile defence at the People's Liberation Army in the past and also was the CEO of a joint venture from China's Ministry of Public Security that specialises in security, and possibly surveillance.

Though most Western social media companies are blocked in China, Twitter serves advertisers in the country who wants to reach a global market. Kathy Chen led that charge, but a reorganisation in the Asian region, which resulted in the exodus of those in charge of Australia, Southeast Asia, and India, now means that it is the Asia Team that is handling Chinese clients, resulting to Kathy Chen leaving the company with no direct replacement.

7/12 Now that the Twitter APAC team is working directly with Chinese advertisers, this is the right time for me to leave the company.

In a series of tweets announcing her departure, Kathy Chen claimed that Twitter had increased revenue from Chinese ad partners by almost 400 percent over a couple of years. She also added that the Hong Kong office will remain open despite her leaving and refuted reports that it would be shut down.
