Then I tell him what it was like for me and my son two Sunday mornings ago, when our cars crashed head-on.
It's not your average restorative justice meeting.
Queenstown court officials who usually oversee the process have gone home, so a police officer steps in as mediator.
My son can't see over the dashboard, I explain to Wu, so the explosion of noise and the shattering shock of the smash in Gibbston was a mystery.
''I turned and my 6-year-old, sitting in his booster seat, was crying from pain and shock.''
Through his interpreter, Wu says he has a 5-year-old, so he understands.
Earlier, in court, his lawyer says his second child has just been born - another reason for him to return quickly to China.
''Congratulations on your new child,'' I say to Wu.
In our crashed car, the dashboard shunted my knee and smoke from the engine seeped in.
The driver's door was stuck so I had to shoulder my way out.
''We're both lucky,'' I tell Wu.
''My son and I were able to walk away, even though I'm injured.
''My feeling is if our car had not been in your way, you would have skidded off the road and down a steep bank.''
More translation: ''He thinks so, too.''
Wu told police he took the corner wide to give an oncoming car room.
But what caused the crash, I ask. Inexperience? Slippery conditions? Unfamiliar roads?
''I don't know,'' comes the translated answer.
I explain his car emerged from fog, skidding out of control into our path. I had no time to react.
Was it foggy as he rounded the bend?
''It was a stressful time. He doesn't remember,'' the interpreter says.
Wu (34) has had a driver's licence for six years. In his city, the traffic is so congested there's little chance of driving quickly.
Before he got behind the wheel in New Zealand, the rental car company had explained our road rules.
His interpreter says he was going well under 100kmh - suggesting caution - when his rental car's left wheel hit gravel, prompting him to overcorrect and lose control.
But he'd been told Kiwi drivers are impatient and he was afraid of driving too slowly.
It's a damned-if-you-don't, damned-if-you-do driving strategy.
We all make mistakes, I tell Wu. I ask the interpreter to tell him that his actions have consequences on real people, with families.
Once the Mandarin version of my words is finished, he says in English: ''Sorry.''
Restorative justice, the offer of which was made mandatory three years ago, has been dismissed by some as time-wasting, touchy-feely nonsense.
But, personally, I found it satisfying to face the guy and tell him what it was like for us.
Official crash statistics, smoothed over five years, show 25% of crashes in the Queenstown-Lakes involve an overseas driver.
More generally, about a third of at-fault overseas licence-holders failed to adjust to New Zealand rules or conditions.
Billboards, posters, keep-left arrows and no-passing lines don't appear to be making much of a difference.
As we wait for the judge, Wu's interpreter says he's decided never to drive in New Zealand again.
• Xin Wu (34) was ordered to pay $1250 emotional harm reparation, a $500 fine and $130 court costs by Judge Mark Callaghan in the Queenstown District Court on Monday after admitting careless driving causing injury to three people, Mr Williams and Wu's two passengers.
Mr Williams sustained chest, shoulder, neck and head injuries. His son was uninjured.
