Mr Zheng told Sky News that it was his “duty” and he was at the demonstration “peacefully”.
What happened outside and on the grounds of the consulate is now the centre of a diplomatic incident.
The pro-democracy protest by Hong Kongers started off peacefully but banners and posters, which the Chinese say they found deeply offensive, were torn down by officials including the consul-general.
That led to a violent clash which saw Bob Chan apparently dragged into the consulate grounds and beaten by its staff – leaving him with cuts and bruises all over his body.

Protester on ‘assault’ at China consulate in Manchester
But these claims have been refuted by Mr Zheng, who said: “I didn’t beat anybody. I didn’t let my people beat anybody. The fact is, the so-called protesters beat my people.”

However, when asked about the hair-pulling incident, he said: “He (Bob Chan) was abusing my country, my leader, I think it’s my duty.”
Mr Zheng added: “I think it’s an emergency situation – that guy threatened my colleague’s life, and we tried to control the situation. I wanted to separate him from my colleagues – that’s a very critical point.”

Moment protester was beaten at Chinese consulate
‘They used very rude words – unacceptable’
Asked why the peaceful demonstration turned violent, Mr Zheng claimed it was because of the “rude banners” that had been put on display.
In a letter sent to Greater Manchester Police, he stated the banners featured a “volume of deeply offensive imagery and slogans”, including a picture of the Chinese president Xi Jinping with a noose around his neck.
“I think the most serious reason for this incident is because they used very rude banners. They used very rude words, unacceptable. Everybody never accepts these kinds of words,” Mr Zheng told Sky News.
“It’s not right to put such banners close to my gate. After I advised them to remove very politely, they refused.”
‘I was under attack’
In his letter, the consul-general also said he was disappointed police didn’t do more to help and claimed one of the protesters grabbed a member of his staff “by the neck and refused to let go” during the ensuing scuffle.
“I was under attack by the protesters and my colleagues were under attack and at that time, we didn’t receive any protection from the policeman, so we had to do something to protect ourselves,” Mr Zheng said.
He added some of his staff were injured during the incident, with video footage showing a man allegedly from the consulate being kicked by protesters whilst on the floor.
“It’s a very serious harassment for me, the consulate and China,” he added.

Protester beaten at Chinese consulate
Protester was ‘kicked and punched’
The protester at the centre of the controversy, Bob Chan, fled Hong Kong to the UK for his safety last March, but explained how he thought he was going to die during the incident.
“I held onto the gate where I was kicked and punched. I could not hold on for long and was eventually pulled into the grounds of the consulate,” he said.
“I’m shocked and hurt by this unprovoked attack. I’m shocked because I never thought something like this could happen in the UK.”
But it did happen here, and it’s now an issue on the agenda of the foreign secretary, James Cleverly.
It’ll be down to police to decide if any criminal justice action is needed – and for the government to determine whether there are diplomatic consequences.
Boris Johnson claims he considered authorising a raid on a warehouse in the Netherlands during the pandemic to retrieve COVID-19 vaccines.
In his upcoming memoir, he described meeting senior military officials in March 2021 to discuss the plans, which he admitted were “nuts”.
Another extract from his upcoming book, released by the Daily Mail, describes Mr Johnson trying to convince the Duke of Sussex not to move to the United States.
He said Downing Street and Buckingham Palace asked him to speak to Prince Harry in January 2020, hours after announcing he and his wife Meghan planned to step away from royal life.
According to Mr Johnson, who was prime minister at the time, there was “a ridiculous business… when they made me try to persuade Harry to stay. Kind of manly pep talk. Totally hopeless”, the Daily Mail reported.
The men met for 20 minutes on the sidelines of a UK-Africa investment summit in London’s Docklands.
Meanwhile, the latest extract describes Mr Johnson writing about a point during the pandemic when AstraZeneca was “trying, in vain” to export the vaccine to the UK from Holland.

At the time, the AstraZeneca jabs were at the heart of a cross-Channel row over exports.
He wrote he “had commissioned some work on whether it might be technically feasible to launch an aquatic raid on a warehouse in Leiden, in the Netherlands, and to take that which was legally ours and which the UK desperately needed”.
He believed the EU was treating the UK “with malice and with spite” due to the European rollout being slower than in the UK.
The extract says military chiefs told Mr Johnson the plan was “certainly feasible”, using rigid inflatable boats to navigate Dutch canals.
But the senior officer said the UK would “have to explain why we are effectively invading a long-standing Nato ally”.
“They wanted to stop us getting the five million doses, and yet they showed no real sign of wanting to use the AstraZeneca doses themselves,” Mr Johnson wrote.
A weather warning for wind has been issued for Wales and southwest England on Sunday after rain battered parts of the UK this week.
The yellow warning covers Cardiff and West Wales, as well as most of the South West from Weston Super Mare in the north and Swanage in the south to Penzance, Cornwall.
According to the Met Office, it begins at 9am on Sunday and lasts until midnight.
They said in the warning Sunday will start dry and clear for most of the country, but wind and rain will then move in from the South West.
Wind speeds are set to get up to 55mph in affected areas, and possibly reach 60mph in exposed coastal regions.
Gusts will be accompanied by outbreaks of rain, which could lead to surface water on roads and public transport delays, according to the Met Office.
Winds will then gradually ease across Wales and inland parts of southwest England throughout Sunday evening, but the weather agency warned it may remain fairly windy along some coasts overnight.

In their outlook for Monday to Wednesday, the Met Office said “unsettled” conditions will remain for the start of the next week, “with heavy rain and brisk winds and temperature on the cool side”.
It added conditions will be “slowly brightening up from the west as we head through Tuesday and into Wednesday”.
It comes after heavy rain and flooding struck across the UK this week, with an amber warning issued by the Met Office.
The Environment Agency said around 650 properties were flooded in Bedfordshire, Northamptonshire and the Home Counties.

From Monday: House flooded as heavy rain hits UK
Areas affected by the heavy rain included Milton Keynes, Oxfordshire, Cambridgeshire, Leicestershire and the West Midlands, which were hit by flash floods.
The Met Office said the regions could have had 30-40mm of rainfall within three hours.
When 19-year-old Shawn Seesahai was beaten and hacked to death in a savage machete attack in a Wolverhampton park, detectives were shocked to discover his killers were just 12 years old.
Days earlier, in another part of the country, Alfie Lewis, 15, was stabbed to death by a 14-year-old boy outside a primary school in Leeds.
Later the same month, a girl and boy went on trial in Manchester for what was described as the “sadistic” knife murder of 16-year-old Brianna Ghey when they were both aged 15.
Murders carried out by children have always horrified us as a society – but are they getting more common or are killers getting younger?
A Sky News analysis of the available Office for National Statistics data on the number of suspects aged under 16 who have been convicted of homicide – murder, manslaughter and infanticide – shows a relatively flat trendline from 2006/7 to 2022/3.
The percentage of homicide convictions going to under-16s compared with other ages doubled over 10 years, however, from about 1 in 50 in 2012/13 to 1 in 25 in 2022/23.
The 2022/23 figure is the highest since at least 2008/09, but as the percentage of under-16s is low overall the averages can be heavily skewed by relatively few convictions.
‘Much more serious and extreme’
Dr Simon Harding, a criminology expert, thinks there’s been “an increase in serious violence in young people” and that there is a greater “acceptance of extreme levels of violence between” children.
“Even something that might have been settled with fisticuffs or anti-social behaviour can suddenly dramatically turn into something much more serious and extreme,” he says.
“What 10 years ago might have been a punch in the face, five years ago might have been a stab to the arm or leg is now a stab to the neck or heart, which can lead to death.”
Bardia Shojaeifard was found guilty of murder after a jury heard how he attacked Alfie on his way home on 7 November last year “in revenge” for an altercation a week earlier.
He had posed for pictures with knives and took a 13cm-long kitchen knife he used to kill Alfie from his home with him to school in the Horsforth area of Leeds.
Sentencing him to life detention with a minimum term of 13 years in June, a judge described Shojaeifard as “outwardly normal” but with a “worrying interest in knives”.
Shawn, who had been walking through Stowlawn playing fields in Wolverhampton with a friend on 13 November last year, was struck on his back, legs and skull, while the fatal wound was more than 20cm deep and punctured his heart.
The boys responsible, the UK’s youngest knife murderers – who were detained for at least eight-and-a-half years – are believed to be the youngest children to be found guilty of murder since Robert Thompson and Jon Venables.
Thompson and Venables were aged just 10 when they abducted, tortured and murdered two-year-old James Bulger in 1993 and 11 when they were found guilty of murder.
A quarter of a century earlier, 11-year-old Mary Bell was sentenced to life detention in 1968 after being found guilty of manslaughter for fatally strangling two boys, aged four and three.
She was also aged just 10 at the time she killed her first victim.
But Sharon Carr is believed to be the youngest girl in the country to have committed murder.
Carr was 12 when she fatally stabbed and mutilated stranger Katie Rackliff, 18, after she left a nightclub in Camberley, Surrey, in 1992, but she wasn’t convicted for another five years.
In another crime that shocked the nation, Ricky Preddie was 13 and his brother Danny was 12 when they killed 10-year-old schoolboy Damilola Taylor in 2000, although they weren’t jailed for his manslaughter until 2006.
Is there now a greater ‘willingness to inflict pain’?
So there have always been cases of children who commit murder and other shocking crimes, but Dr Harding says: “We just tend to forget.”
However, from his experience preparing expert reports on court cases involving gang crime, exploitation and modern slavery, he says he has noticed a greater “willingness to inflict pain and suffering”.
Earlier this year, Scarlett Jenkinson and Eddie Ratcliffe were jailed for life with minimum terms of 22 years and 20 years respectively after they were found guilty of murdering Brianna when they were both aged just 15.
Jenkinson lured the vulnerable teenager, who was transgender, to Linear Park in the village of Culcheth, near Warrington, where she was stabbed 28 times in the head, neck, chest and back with a hunting knife on 11 February last year.
The pair had a fascination with violence and torture, prepared a “kill list” and meticulously planned Brianna’s “frenzied and ferocious” murder for weeks, their trial heard.
Jurors were told it was “difficult to fathom” how they could share such “dark thoughts” and carry out such a “disturbing” crime.
Beyond the high-profile cases that attract significant media attention, much of the country’s gang violence, including children killing other children, is largely hidden from the public, says Dr Harding.
He’s seeing “quite extreme things that wouldn’t happen a few years ago”, such as disabled people subjected to levels of cruelty bordering on torture, and young women raped and waterboarded by the people forcing them to sell drugs.
A different Dr Harding, forensic psychiatrist Dr Duncan Harding, works with adults and children who commit serious crimes. He says we really don’t know if killers are getting younger or youth violent crime is increasing because the evidence just isn’t there.
But the reporting of crime and the expansion of social media use means cases which may not have passed the threshold for widespread coverage in the past gain more traction, adding to a perception that it is.
‘Dehumanisation is spreading’
Even if youth violence isn’t on the rise, the “horrifying” crimes we see reported aren’t acceptable and we have to, as a society, try to understand what’s going on and try to improve things, Dr Duncan Harding adds.
The psychiatrist, who has provided expert evidence in court cases involving homicide, serious violence and terrorism, and has recently released his memoir The Criminal Mind, says the “dehumanisation” seen in gang violence seems to be spreading beyond gangs.
Our divided society is suffering an existential crisis since the COVID-19 pandemic, which is exacerbated by social media, he says, and he also highlights cuts to services for young people due to austerity as a potential factor.
But “stripping away youth clubs isn’t going to in itself lead to someone who’s going to stab or kill someone”, he says, and children don’t always commit violent crimes because of mental illness or difficulties in their lives.
“Obviously, they’re not normal, well-adjusted people, but in my experience, it’s not as straightforward as that either,” he says. “I don’t think that all offenders are victims.”
‘You have to have proper sentencing for knife crime’
The potential solutions are just as complicated – the psychiatrist suggests a public health approach that recognises the “epidemic” of knife crime among vulnerable young children, with schools, health workers and police working together to spot the early warning signs.
But he also supports the wider use of stop-and-search and the government ban on so-called zombie-style knives to try to keep weapons out of children’s hands, and says there need to be consequences at the point where youngsters are carrying knives.
Shawn’s parents urge children to “think about what they’re doing” and not to carry a weapon, but want to see tougher sentences for youngsters like the boys who killed their son.
“You have to have a proper sentencing for knife crime,” says his father Suresh Seesahai.
“Murder is murder. Murder is no coming back. If you murder someone they can’t come back… Life sentence is the best for you.”
