Yakubu has left relegated Blackburn to play for Chinese club Guangzhou R&F but insists it's not for the money.
"Many will ask why China? The truth is there is not much to prove after scoring almost a century of goals in a league considered as one of the best in the world," he said.
"I thank Blackburn Rovers, the fans, fellow players for making my one season there seem like a decade - I appreciate their support [and] I hope the club will come back again into the top flight as soon as possible.
"Money cannot buy you happiness and what I have found from the people in China is love, happiness, sincerity and warmth [and] I can't wait to get started here.
"They are starting an unbelievable football programme here and it's nice to be a part of it."
