Shanghai explains expensive car plates

"Regulation of the real estate is a long-term task," Han said. "All the regulating policies are established for maintaining healthy development of the market and effectively curb housing prices to rise too fast."

House prices have risen wildly in major cities like Beijing and Shanghai, to deep dissatisfaction of residents.

"I believe the Chinese real estate market will develop healthily when these measures are implemented," Han said.

Han also felt bitter about the Chinese mainland milk powder manufacturers, when asked twice by the press what he thought of the recent limits of carrying milk powder out of Hong Kong.

On March 1, the Hong Kong authorities put into effect a strict regulation, stipulating outbound travellers could bring with them no more than two cans of milk powder. Violators might face a fine of 500,000 Hong Kong dollars and a punishment of being jailed for two years.

The measure has severely affected mainlanders who previously swarmed to Hong Kong to buy foreign brands of milk powder, believed safer than mainland products.

"The whole society is concerned with the milk powder issue," Han said. "Mainland milk powder manufacturers have the obligations and the government has the duty to ensure the food safety."
