A few days before the start of this year's Melbourne International Film Festival its executive director received an "audacious" telephone call.
BBC News, Beijing
An official from China's consulate in the city called him to "urge" the festival to withdraw a film about the Chinese activist Rebiya Kadeer.
Beijing then tried to persuade the organisers of the Frankfurt Book Fair not to allow two Chinese writers to attend an event.
China says it does not interfere in the internal affairs of other countries.
But some see these acts as an attempt by China to use abroad the tough censorship measures it constantly employs at home.
Intimidation and threats
Richard Moore, the Melbourne festival's executive director, said he was astonished to receive the call from the city's Chinese consulate.
"It came down to [the consular official] saying we need to justify our decision to include the film in the programme. It was a remarkable display of confidence and arrogance," he said.
The festival decided to ignore the advice and go ahead with the film - about an activist who campaigns for better rights for China's Uighur minority - but that did not end the issue.
The festival organisation was subjected to an intense campaign of threats, intimidation and disruption, although it is not clear who - if anyone - orchestrated the campaign.
The festival e-mail address received insulting messages, there were waves of annoying phone calls and the fax machine was jammed with callers.
Some notes to the organisers contained messages threatening Mr Moore's family.
Internet hackers managed to break into the festival's online booking site, making it appear that session tickets had been sold out.
Hackers also managed to post a Chinese flag on the main website and Chinese film-makers withdrew their movies from the festival.
