As the 15th anniversary of Hong Kong’s return to mainland China on July 1 approaches, local journalists say that press freedoms have eroded in recent years and self-censorship is on the rise. According to a survey by the Hong Kong Journalist’s Association, 87% of journalists say that access to information has been limited and obstruction of news coverage has risen in the past five years under Chief Executive Donald Tsang, who steps down from office on June 30. That figure is 29% higher than the results of a similar survey the association conducted in 2007.
