The Italian, 66, stepped aside after winning the Chinese Super League for the third straight season.
Former Italy international Fabio Cannavaro has taken over, with Lippi moving into a chief director role.
Lippi - a 2006 World Cup winner as coach of Italy - said he was still willing to manage at international level.
"The Chinese national team job has been proposed several times, but I said no," Lippi told Radio Deejay.
"When my contract with Guangzhou expires, I can evaluate a national team. I don't feel old yet, but I am done with clubs.
"Guangzhou asked me last year if Cannavaro wanted to come and be our technical director, but Fabio was eager to become a coach.
"Therefore this season, when I decided to leave the post, I gave them two names: Cannavaro and Ciro Ferrara. They are in love with Cannavaro."
