Wen Jiabo yesterday delivered a stern lecture to Macau's ruling elite on their responsibility to the public, especially the poor. Speaking ahead of Macau Chief Executive Fernando Chui Sai-on's policy address tomorrow, the premier said officials must be clean and government transparent. 'Power must operate under the sun,' he told the community leaders on the second day of his first visit to Macau. 'It is important to build a clean, transparent, efficient and people-centred government. It is also important the government works hard to improve the people's standards of living and let the fruits of development be shared by people from all walks of life, especially the poor.' The tough message contrasted sharply with a charm offensive as he toured the city and mingled with ordinary people. Wen showed off his tai chi skills in the morning with a group of middle-aged women at Mount Fortress and invited them to visit him in Beijing. Saying he was left-handed, he shook hands with the crowd visiting the ruins of St Paul's. Wen also visited several community facilities and an 11-member family. But speaking to the elite, Wen said the administration must pay attention to the widening wealth gap between the rich and poor. 'The people's biggest concerns are housing and high consumer prices,' he said. 'The government should take advantage of its robust financial status and spend more money on livelihood issues, such as building more public housing and transport projects.' Chui has been criticised for failing to build more public housing units. Yesterday's speech was the second time the premier raised the issue of clean government in Macau. Talking to top officials on Saturday after meeting Chui, Wen said their duty was to serve the 500,000 people of Macau. He told them to 'put the people in your heart, [and] the people will put you in their heart'. 'The weight of the people in your heart is connected to the weight of you in the people's heart,' he said. 'Being clean is particularly important in Macau. Only when you are clean [do] you have authority. If you say one thing on the stage and behave differently behind the scene, you do not have authority.' Chui reappointed all but one major official when he took over from former chief executive Edmund Ho Hau-wah last year. The official was former commissioner of audit Fatima Choi Mei-lei, who was best known for uncovering major government misspending cases.
