Lau Sai-leung yesterday conceded his poor relationship with the pro-Beijing camp would be a challenge to his job at the Central Policy Unit. 'It's good that the pro-Beijing people make criticisms about me. At least I know they have these opinions. I have to face them,' Mr Lau said on radio after being named a member of the think-tank on Friday. 'It's not about improving [the relationship]. It's doing our job rationally and professionally. I think the most important thing is people can honestly exchange different views in the think-tank ... Mutual trust has to be built through working together.' Pro-Beijing legislator Tsang Yok-sing, former chairman of the Democratic Alliance for the Betterment of Hong Kong, said he would not challenge the chief executive's decision to hire the former Democrat. 'Mr Lau had written a lot of scathing criticisms on patriots in Hong Kong. From my point of view, many of these criticisms were unfair,' he said. 'But all this will not necessarily affect his work with the government. I believe Tsang Yam-kuen fully understood his previous work before hiring him.' In his last appearance as host of the Headliner show last night, Mr Lau presented thin-skinned glutinous dumplings and urged Beijing to be more transparent.
