 I too would like to add my welcome and I'm especially grateful for those of you that have come a long way to attend this conference, a special welcome to our overseas visitors. This collaboration, which we are involved in now, emerged from the University of Hong Kong's Managing World Cities program, which brought Hong Kong U together with LSE and New York University to look at major urban problems. And I'm very happy to say that this year we are focusing on issues that are of great local significance. When we look at the health care system in Hong Kong and how we can make it more sustainable, this is an issue that has plagued Hong Kong for quite some time. The politics of this are well known to all of us and they basically come down to who pays, who benefits, and what should the role of government be, what should the role of the private sector be. And these are issues I'm sure that Secretary Chao will discuss in just a moment. We also at this conference will be looking at issues of balanced development, development and conservation, development and non-development or undevelopment. And these are issues that will be discussed yesterday. The political economy of development is a very important issue, you know, that resonates well in Hong Kong. Another theme of this conference is density, high density living and the quality of life in Hong Kong. And these are also issues which many of you will have observed are characteristics of Hong Kong too as you went on a tour I believe yesterday and looked at some examples of high density living and what the impact of this is. So without saying anymore I would just like to welcome you all to Hong Kong and I'm sure we're going to have a wonderful conference. Ricky.
