The 27-year-old Chen Long, who has yet to play in any competition this year, tops the ranking for the 13th consecutive month with 96,931 points.
The 33-year-old Chong Wei’s meteoric rise has coincided with a resurgence in his form, which has seen him go on a 21-match unbeaten streak since late November.
“I’m delighted with my recent form … haven’t lost a match (since the French Open in November) and winning four tournaments in a row,” said Chong Wei after being unveiled as XOX Mobile brand ambassador here.
Chong Wei believes that he is ready to return to the top position that he once held for six years.
“I’m really surprised with the progress I’ve made in the last nine months. I was No. 182 then … now I’m world No. 2,” he said.
“I have come a long way. It hasn’t been easy to get back to where I am now. If you asked me nine months ago if I ever dreamt of being world No. 1 again, I would probably have told you that it’s not possible.
“Now, I dare to dream again. I’ll try to regain the No. 1 spot … hopefully before the Olympics.”
Chong Wei relinquished his No. 1 spot at the end of 2014 after being inactive since the Incheon Asian Games in South Korea last September. He was suspended indefinitely by BWF on Nov 11 following a positive dope test at the World Championships in Copenhagen, Denmark, on Aug 30.
