CHINA has accused Governor Chris Patten of undermining press freedom in Hong Kong by exerting pressure on the media. The vice-director of Xinhua (the New China News Agency), Zhang Junsheng, denied China would interfere with the territory's press freedom. He said the Governor's call last week for the media to protect press freedom and avoid self-censorship was in itself a form of pressure on the media. ''Press freedom is also facing other forms of challenge, such as pressure, the desire to please, and divisiveness. Hong Kong's media will have a better understanding of the issue than I have,'' he said. Mr Zhang also said the Hong Kong Government was a non-democratic system. A truly free society would only come after 1997, he said. The Deputy to the Governor, Anson Chan Fang On-sang, denied that self-censorship existed in the territory. ''I'm sure that this [press freedom guaranteed by the Basic Law and the Joint Declaration] is an area that the media themselves will be particularly concerned about and will be paying particular attention to both now and after,'' she said.
