Officials were urged to strengthen monitoring of public transport. Legislators approved an amended motion from Albert Ho Chun-yan, of the Democratic Party, who urged the authorities to take a 'more proactive monitoring role' to ensure service quality and fare levels were reasonable. Mr Ho suggested a new, independent watchdog be formed to safeguard the public interest. Colleague Lau Chin-shek said the Mass Transit Railway Corporation, which is to be partially privatised, should not increase fares without Legco's approval. Miriam Lau Kin-yee, of the Liberal Party, who proposed the original motion, urged the Government to promote competition and provide a safe, comfortable, environmentally friendly and efficient system. She said competition, rather than government control, was the best way to keep fares low. Ms Lau urged that management of cross-border traffic be improved. An amendment from Christine Loh Kung-wai, of the Citizens Party, who suggested a road-pricing system be established to manage traffic, was defeated. Law Chi-kwong, of the Democratic Party, said the Government should encourage people to walk by providing more escalators and pedestrian walkways. 'Walking is an important mode of public transport,' he said. Secretary for Transport Nicholas Ng Wing-fu said the Government would study alternative means of public transport and noted that 10 more checkpoints would be set up at the Lok Ma Chau crossing next week.
