The debate between a former Hong Kong leader and the current chief executive over land supply shows no signs of abating, with the former urging the government to provide fuller details of its planning for future development.

Wednesday’s volley by former city leader Leung Chun-ying came a day after Chief Executive John Lee Ka-chiu stressed that authorities must continually create land to maintain control of the market, a rebuttal to Leung’s earlier warning about possible fiscal challenges brought on by oversupply. .

Writing on his social media, Leung said: “Quantitative estimates within the planning (process) may not always be accurate, but supply and demand need to be quantified and refined. »

Leung, now vice chairman of the Chinese People’s Political Consultative Conference, the country’s highest political advisory body, questions whether the city should set aside additional areas for redevelopment, regardless of the cost, if the objective was only to create more land.

If this is not the strategy, what basis did the authorities use to determine the extent of the rehabilitation work needed, he asked.

Leung also made an analogy with manufacturing tong suior Chinese dessert soup.

“Making a sweet soup needs sugar. Does this mean the more sugar the better? The earlier you buy sugar, the better? Should a kitchen store 10 catties of sugar if a family always makes sweet soup? It’s about understanding the quantity and the timing,” he said.
