Story highlights Hong Kong government proposes limiting corporate information available to public

Would remove directors' address, full Hong Kong ID numbers from Company Registry

Journalists, financial firms use it to trace who is running a HK-registered company

Information about wealth of China's elite found by leading news outlets on database

A change in corporate record-keeping in Hong Kong has turned into a flashpoint for the debate about freedom of information in the Chinese territory.

Many in the city take pride in what they say is a transparent and open financial system, in contrast to the situation across the border in Mainland China.

Now Hong Kong's government has proposed limiting the information that is available to the public about corporate directors "to enhance protection of the privacy of personal information."

The plan would remove directors' residential address and their full Hong Kong identification numbers from the Company Registry.

The information is regularly used by both investigative journalists and financial firms to help trace who is running a Hong Kong-registered company.

A petition declaring "Secrecy Breeds Corruption" appeared in the pages of five Hong Kong newspapers Monday morning, followed by the signatures of more than 1,700 journalists, educators and students, who strongly oppose the change.

Information from the database was used in two high-profile stories last year that looked into the wealth of the families of China's ruling elite, which appeared in The New York Times and Bloomberg News . A number of stories on property scandals within Hong Kong also relied on information from the database.

The petition declared the change an "infringement of the public interest," which would have a "great impact on professional and citizen journalists' right to conduct investigative reporting."

Members of the business community and investors have also voiced concerns about the proposed change. David Webb, a well-known investor activist and editor of Webb-Site.com , says the change would make it harder for investment banks and IPO sponsors to determine a person's real assets.

"It basically undermines our reputation for free markets, transparency and the rule of law," Webb said.

Issues like this one often flame fears in Hong Kong about the interference of the Chinese government in the city's affairs.

Hong Kong, a former British colony, is part of China but maintains freedom of the press, speech and no Internet controls.

Residents are often fiercely vocal in response to anything they see as infringement of these rights.
