RTHK has shown more self-restraint in criticising the Chinese leadership, a veteran pro-Beijing figure said yesterday. Xu Simin, a member of the Chinese People's Political Consultative Conference, said the broadcaster had performed differently since his remarks. He criticised RTHK last summer after Taiwan's then de facto envoy Cheng An-kuo discussed President Lee Teng-hui's 'two states' theory on air. Mr Xu said yesterday: 'Although they continue to abuse or make jokes with people, they are no longer so impolite. 'They keep criticising the Chinese leadership, but in a more restrained manner . . . they are telling the truth comparatively,' he said on his arrival for the conference plenum in Beijing which starts today. Mr Xu refused to say if he was satisfied with RTHK's performance but said more promotion of government policy was needed. He said he had a higher expectation of RTHK simply because he was a taxpayer. He also said he would pass on his views to Director of Broadcasting Chu Pui-hing. An RTHK spokesman said yesterday the station had long-insisted on its editorial independence and balance of coverage. As a public broadcaster, its first duty was to serve the people of Hong Kong and reflect the views of different sectors rather than to promote a single viewpoint, he said.
