World Peace, who is infamous for his on and off court brawls and controversies, recently represented the Sichuan Blue Whales, where he averaged 19 points and six rebounds in 15 games.
"I had an up and down career," the 35-year-old told ESPN. "I grew up playing basketball on the streets of New York City and it was very, very rough and I started playing in the NBA in the same way.
"Now the mentality is different from when I was younger. I always had the street mentality, but when you're older, you get more mature."
World Peace has confirmed that he will retire from basketball when he is 40 and in the five years he has left, he hopes to completely transform his image from a brutish brawler to a calm and passionate individual.
"When you play angry you can't focus," he said. "I've got five more years to have a great time, so I will be playing with a lot of fire but not anger, just passion."
World Peace, who changed his name from Ron Artest, has now decided to sign for Pallacanestro Cantu in Italy as he has "always wanted to play in Europe".
"I always wanted to play in Europe for a long time," he said. "They move the ball and they move bodies and that's what I like doing. I'm looking forward to playing team basketball and being smart as well as scoring. I can score but I'm excited about team basketball."
