Airport Authority chairman Wong Po-yan is to step down to spend more time serving on mainland government bodies. The 74-year-old industrialist, who recently took the reins at ATV, said he would not accept reappointment after his three-year term ended in November. A trusted friend of Beijing, he said he would continue serving the National People's Congress and on its Basic Law Committee. 'One should not occupy a position for too long. I think others should take over,' said Mr Wong. He said the 1996 controversy over budgeting $1.9 billion extra to settle contractual claims was the most difficult decision in his term, but he had proved his critics wrong because the money guaranteed the completion of the airport on time, he said. 'It was something costing the public $1.9 billion. But we had to go ahead or we might have lost more,' he said. Mr Wong yesterday reiterated the authority had no intention to cut landing fees. 'Hong Kong's airport is of a high standard and I do not think our status can be challenged by our competitors because they charge less.'
