Chan competed in
badminton at the 2004 Summer Olympics with his then partner,
Chew Choon Eng. In the first round, they defeated
Theodoros Velkos and
George Patis of Greece, but were then defeated in the round of 16 by
Zheng Bo and
Sang Yang of the China. After his unsuccessful outing in the Olympic Games, Chan's regular doubles partner was changed to
Koo Kien Keat. Together, they claimed 2005 Denmark Open title. Chan Chong Ming and Koo Kien Keat won the Malaysia Open in 2006 which was held in
Kuching, Sarawak and became the new hope for Malaysia in the men's doubles. However, at the
2006 World Championships, they conceded a walkover due to Chan's father's death. In the Swiss Open, Chan and Koo defeated Carsten Mogensen and Mathias Boe in a thrilling 17–14, 8-15, and 17–14 final match. On the run up to the
Doha Asian Games XV, Chan sustained an injury which prompted their coach,
Rexy Mainaky, to split them, partnering
Koo Kien Keat with
Tan Boon Heong for the games instead. Chan and Koo's partnership ended when Koo won the title with his new partner. Chan's partner was changed to
Hoon Thien How who was
Tan Boon Heong's ex-partner. Chan and Hoon won the Kuala Lumpur Open at the end of 2006. Chan and
Hoon Thien How won their first title in
New Zealand after beating Johan Wiratama and Albertus Njoto of Hong Kong. Chan paired again with Chew. In the late 2008, Chan established a company named Pioneer Sdn Bhd with
Wong Choong Hann,
Choong Tan Fook,
Lee Wan Wah and
Chew Choon Eng. They trained young players in the two centres in Kota Damansara and Bandar Mahkota Cheras. Chan married Janice Lee on 6 January 2008. == Achievements ==
