A Hong Kong pro-independence activist has labelled Beijing’s rule as modern-day colonialism in a speech to foreign journalists that defied the Chinese government’s demand to cancel the event.

The government’s demand raised questions about Beijing’s growing influence in the former British colony, which was promised semi-autonomy and freedom of speech as part of the 1997 handover.

The Chinese government swiftly criticised the talk, saying that freedom of speech in Hong Kong does not extend to discussions of independence for the Chinese city, which it said was a threat to national security.

“We express our indignation and condemn it,” the Chinese foreign ministry office said.

President Xi Jinping and other officials have warned that separatist activity would not be tolerated.

Some pro-Beijing protesters carried banners saying “Hong Kong independence is poisonous”.

Current and former Hong Kong leaders have criticised the FCC for hosting Mr Chan, whose party is facing a possible ban on national security grounds.

“Sadly, we are a nation that is quickly being annexed and destroyed by China,” Mr Chan told the audience at the FCC event.

“The cry for Hong Kong independence is therefore a cry against colonial invasion.”

The 75-year-old FCC has previously hosted politicians and newsmakers, including pro-Beijing speakers, at its iconic clubhouse in central Hong Kong.

It says it believes its members and the public have the right “to hear the views of different sides in any debate”.

The perception that Beijing is reneging on its promise and eroding Hong Kong’s free elections and freedom of speech is helping fuel a rising generation of young activists calling for greater autonomy, if not outright independence.

Huge pro-democracy protests erupted in 2014 in response to the decision by China’s ruling Communist Party to retain the right to effectively pre-screen candidates for Hong Kong’s leadership.

Hong Kong officials have dismissed the FCC’s argument that Mr Chan’s appearance amounts to a free speech matter, with the territory’s former chief executive CY Leung equating the FCC event with giving a platform to “criminals and terrorists”.

Hong Kong leader Carrie Lam told reporters on Sunday that it was “inappropriate” for the FCC to host Chan and asked the organisation to respect that Hong Kong is an unalienable part of China.
