Singapore pop star Stefanie Sun opened her concert in Shenzhen on Saturday night with a minute of silence for Mr Lee Kuan Yew.

The concert in south China, which is part of her Kepler World Tour, began with the singer rising from the stage in a darkened hall of the Shenzhen Bay Sports Centre.

A message flashed on a screen: "Pls allow me a minute to pay tribute to the person I most respect."

The platform she was standing on, rose to half the height it usually ascends to, as a sign of respect for the late Mr Lee, Shin Min Daily News reported.

She then started the concert with her hit song from 2000, Cloudy Day.

Many Singaporeans may remember how last Wednesday, Sun was seen queueing with the public in the day to get into the Parliament House to pay her last respects to Mr Lee's, whose body was lying in state for the first of four days before Sunday's State funeral.

She had delayed flying to Shenzhen so she could pay her last respects, Shin Min reported.

She also collaborated with a group of Singapore artists to produce a new rendition of the national anthem Majulah Singapura in a music video.

She was in China while the video was filmed, but she sent a recording of her voice so it could be mixed into the performance.

Sun met Mr Lee a few times. She wrote about those experiences in a Straits Times article that appeared just after Mr Lee turned 90 in 2013.

Here's what she wrote then:

"I remember vividly my meetings with Mr Lee. Some were formal and austere, rather quiet and awkward - or at least in my imagination. But there were also fleeting moments of intimate friendliness and genuine warmth.

"It was hard to not be in awe of this man. I remember thinking to myself: This must be what it feels like to be a fan.

"I remember one incident when we were to be photographed together. As I kept a respectful distance, he impatiently asked me to move closer to him.

"Another time, he was in good spirits and asked me jovially who was the lucky man I was married to." (Sun, 36, married Dutch entrepreneur Nadim van der Ros in 2011 and gave birth to a son in 2012)

"I remember singing his wife's favourite song, Que Sera Sera, at the Business China Awards in 2011, not long after her demise.

"(Senior Minister of State) Josephine Teo later told me in private that she saw tears in his eyes.

"That was probably one of my proudest moments as a singer."
