Sun Yue signed his first professional contract with Chinese Basketball Association side Beijing Olympians in 2002 at the age of 17. In 2004, Sun was selected to the Chinese national under-20 team, but when Beijing refused to release him to play, the team was banned from playing in the Chinese Basketball Association. After touring in Taiwan, the team moved to play in the American Basketball Association. In Sun's first season in the American Basketball Association, he scored 9.5 points per game and seven rebounds per game with 6.7 assists per game. Sun also had his first triple-double of his career with 12 points, 12 rebounds, and 14 assists and was named to the All-ABA second team. In the following season, Sun improved his numbers, making the All-ABA first team with 13.5 points per game and six rebounds per game with 10.5 assists per game. Sun rejoined the Beijing Olympians after he was released by the Los Angeles Lakers in 2009. After playing several more seasons with the Beijing Olympians, Sun then signed with the Beijing Ducks of the Chinese Basketball Association in 2013. He played a vital role in helping Beijing win their second CBA championship title during the 2013-14 season. Not only that, but he also provided a useful role in helping Beijing repeat as champions a year later.
NBA career
After originally entering the 2006 NBA Draft but subsequently withdrawing, Sun decided to enter the 2007 NBA Draft and was taken by the Los Angeles Lakers as the 40th overall pick. With Sun being drafted alongside Yi Jianlian that year, it marked the first time in NBA draft history that two China-born players were drafted in the same year. That feat would not be repeated until 2016. It would also be the first time in modern NBA history that a Chinese basketball player would be drafted outside of the CBA. However, Sun stayed with the Beijing Olympians for another year before signing with Los Angeles in August 2008. Only a few days after his arrival in the United States, Sun suffered from a bout with mononucleosis and had to be hospitalized. After recovering from his illness, Sun finally made his debut on 7 December 2008 against the Milwaukee Bucks, scoring four points in five minutes of play. Sun played in a total of ten regular season games and averaged 2.8 minutes and 0.6 points per game before being assigned to the Lakers' D-League affiliate, the Los Angeles D-Fenders. He played six games with the team, averaging 0.7 points and 0.2 assists per game. Sun then suffered a left ankle sprain during practice with the D-Fenders and missed the remaining D-League games. Sun eventually recovered and traveled with the Lakers as a member of their playoff roster, but he was not activated. Since he was a member of the team when the Lakers ultimately won their championship, he did receive a ring and was crowned as an NBA champion. He is the first ethnic Chinese player to win an NBA championship. Following the death of Kobe Bryant in 2020, Sun posted a tribute to Bryant on his Weibo account, writing: "After I came to the Lakers, I was lucky to be your teammate. This is the dream of many people." Sun was waived by Los Angeles on 31 July 2009. He then joined the New York Knicks, but was waived on 7 October 2009, before the next season started, due to a stress fracture in his knee. He did not play for two seasons until returning to the CBA in the 2013–14 season.
