Politicians expressed shock at David Chan's death and called on China and Japan to solve the dispute quickly. Unionist legislator Chan Yuen-han said she and colleagues Cheng Yiu-tong and Chan Wing-chan would suggest a minute's silence before today's Legco House Committee meeting. Preparatory Committee member Xu Zemin, who bade farewell to the protesters at Queen's Pier on Sunday, said: 'I'm so sad that I don't know what to say.' Independent legislator Chim Pui-chung, who gave Chan $300,000 to hire the Kien Hwa No 2, said he hoped the tragedy would persuade Japan to dismantle the lighthouse. Executive Councillor Professor Edward Chen Kwan-yiu, who taught Chan at the University of Hong Kong, said: 'I'm worried about the public sentiment in Hong Kong and whether Hong Kong people can rationally look at the issue of Diaoyu Islands.' The Association for Democracy and People's Livelihood has petitioned Xinhua (the New China News Agency), demanding China send troops to recover its sovereignty over the disputed islands. But the Democratic Party and Liberal Party called on Beijing to resolve the dispute through negotiation.
