I REFER to John W. S. Chan's letter headlined, ''Must start talking'' (South China Morning Post, April 1). Of course everyone favours talks between China and Britain, but that does not mean that the British must give in to every demand the Chinese make. This transition is supposed to be undertaken by way of compromise, but this seems impossible while the Chinese leaders constantly shirk their obligations to talk, fussing like silly little children at every turn. As you may or may not know, Mr Chan, the British are perfectly willing and completely prepared to sit down and hold talks. Why is China so recalcitrant? Their opportunities to make something of this transition await them. If only they would open their eyes and actually do something constructive, instead of blocking all chances for co-operation. And why should the Hongkong delegates to the British negotiating team not be counted as full members? Obviously the Chinese leaders do not care one bit that the Hongkong people are going to be the ones most affected by the transition. And I assume that includes you Mr Chan. Haven't you any self-respect as a Hongkonger? Do you not believe that the thoughts and desires of the people of Hongkong should demand full representation in any talks? If not, I see no credibility whatsoever in any of your arguments, as you obviously care as little as the Chinese about the plight of your fellow citizens. And Mr Chan, since you point out the 27 per cent support for Mr Patten's reforms, answer me this: What percentage of Hongkong people want to live under the tyrannical boot-heel of Chinese communism?
