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 men's doubles. However, at the XV World Championships in 2006, 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.
