A retired top adviser to the Chief Executive has urged Tung Chee-hwa to seek Beijing's blessing for political parties to have a greater role to help break the impasse in the present political system. Speaking in an interview with the South China Morning Post about his memoirs, Dr Chung Sze-yuen said party politics was an inevitable and integral part of an effective democratic system. Without the support from political parties in the elected legislature, he warned a ministerial system would be 'neither this nor that', and even counter-productive. Recalling his attempts to lobby for the grooming of political parties in the 1980s and propose a ministerial system during the transition, the former convenor of the Executive Council lamented his advice had been ignored. 'He [Mr Tung] only came out in 1996, he did not have much experience in politics. Nor has he time to read books. After he came to office he had to change a lot of policies set by Chris Patten. It took time for officials to adjust to the changes.' He said China had to take the blame for failing to lay down the blueprint for the transition of a colonial system to a democracy system in the Basic Law. 'Mr Tung should not be blamed for not doing something about it in the early years. But in the next five years, he should think of ways to better deal with the problem,' Dr Chung said. He said he was baffled by the new law governing the chief executive election that banned the successful candidate from holding party membership. 'Do nominees from the Chinese Communist Party also have to quit the party after they take office? It's anti-democratic and baffling to me,' he said. Dr Chung admitted Beijing was worried about democrats in Hong Kong. 'Beijing feels very scared that the Chief Executive will be very powerful if he or she aligns with Legco. And if Legco is controlled by the democrats, it will become another Taiwan,' he said. 'We should seek the blessing of Beijing and form a coalition. The Government should sit down with the Executive Council and the Legco to work out solutions and move forward.' Hong Kong faced a double blow with changes impending to its economic and political structure. 'We have a choice between long pain and short pain . . . I don't want to say Hong Kong will be heading for decline. But if we sit idly and delay action, we will be neither here nor there. I'm most worried about this scenario. 'Twenty years ago, Hong Kong was the only city that China could rely on for investments. Now we have Beijing, Shanghai . . . Hong Kong may still be better, but it's just one of them. 'I think Beijing now hopes Hong Kong not so much facilitates the Chinese economy, as does not become a liability.'
