Hong Kong's embattled leader insisted Tuesday she had no intention of stepping down after an audio recording emerged of her saying she wanted to quit over three months of unrest in the southern Chinese city.

Hong Kong has endured dozens of sometimes violent pro-democracy protests triggered by opposition to Chief Executive Carrie Lam's bid to push through a law allowing extraditions to mainland China.

The protests have evolved into a wider democracy campaign involving clashes between protesters and police, in the biggest challenge to China's rule of Hong Kong since its 1997 handover from the British.

"I told myself repeatedly in the last three months that I and my team should stay on to help Hong Kong," Lam told a press conference on Tuesday morning.

Lam said she had "not even contemplated" discussing her resignation with the Chinese government, which gives Hong Kong a restricted form of autonomy.

"The conflict that I myself want to quit, but cannot quit, does not exist," she said.

Lam was speaking after Reuters news agency released an audio recording of her telling business leaders last week that she wanted to step down and take responsibility for the unrest.

"For a chief executive to have caused this huge havoc to Hong Kong is unforgivable," an emotional Lam said in the audio recording.

"If I have a choice," she said, speaking in English, "the first thing is to quit, having made a deep apology."

Lam told the business leaders she had "very limited" room to resolve the crisis because it had become a national security and sovereignty issue for China.

On Tuesday afternoon, Beijing repeated its support for the chief executive, but warned it would "never allow the situation in Hong Kong to continue unabated".

"If the situation continues to deteriorate and moves into the turmoil that endangers national sovereignty and security, that is beyond the control of the (Hong Kong) government, the central government will never sit idly by," said Xu Luying, spokeswoman for the Hong Kong and Macao Affairs Office of China's central government.

'Carrie Lam lied'

However, in the leaked recording, Lam said she believes Beijing has "absolutely no plan" to send in its People's Liberation Army: "They know that the price would be too huge to pay."

She also claimed that Beijing "does not have a deadline" for clamping down on the unrest and that celebrations on October 1 -- the 70th anniversary of the People's Republic of China expected to trigger huge protests -- would go ahead in a modest way.

Lam has described the leak of the recording as "unacceptable", and denied that she or her government had orchestrated it.

But protesters online have accused the leader of trying to drum up sympathy for her position.

"Either Carrie Lam lied to the business leaders last week or to the public of Hong Kong this morning," said pro-democracy lawmaker Lam Cheuk-ting.

On Tuesday, high-profile activist Joshua Wong, who was arrested last week over the protests, travelled to neighbouring Taiwan to urge its political leaders to accept protesters who want to flee, and to help "safeguard" the city.

Beijing regards Taiwan as a part of China awaiting reunification, but the island is a self-ruled democracy.

Crowds filled a city park on Tuesday afternoon in the latest organised demonstration, but tensions flared in the evening when small groups of protesters played a cat-and-mouse chase around the city with riot police.

Video of police chasing and tackling a teenager at the Prince Edward subway station just before midnight Tuesday was widely shared by opposition politicians and activists.

The boy apparently had a seizure and fainted after six officers subdued him in full view of a crowd snapping pictures and shooting video. Police dragged him away before first aid was administered, and eventually the teen was rushed to a hospital on a stretcher with neck support.

Earlier in the day, Ivan Lam, the chairman of pro-democracy party Demosisto, which helped organise the class boycott, was arrested at Hong Kong airport on suspicion of "inciting others to join an unauthorised assembly", the party said.

More than 1,100 people have been arrested since June when the unrest began, including a swoop of key pro-democracy leaders and politicians.

China has responded by ramping up threats and intimidation, including by warning its security forces could intervene.

Chinese state media have released videos showing mainland security forces deployed just across the border.

An editorial by China's state news agency on Sunday warned the protesters that "the end is coming".
