Klitschko earlier told a press conference on Monday: "The Ukrainian flag will keep flying high and our national anthem will keep playing when Klitschko comes onto a ring. But if you're talking about me, I'm not going to box.
"I've got a brother who looks like me but he's younger and more talented than me. So I mean that will be Vladimir"
However, the 41-year-old soon released a statement on his Facebook page to make clear he is not yet considering bringing his 16-year career to a close.
"There is no talk about the end of my career," he said. "I'm sorry if I didn't put enough emphasis on this at the news conference."
Klitschko has held the WBC edition of the world title on two occasions since April 2004, the second and current reign spanning nearly four years.
The Ukrainian had lost two fights prior to his victory over the recently-murdered Corrie Sanders for WBC title number one: to Chris Byrd in 2000 for Klitschko's WBO championship and to Britain's former unified world champ Lennox Lewis in an unsuccessful challenge of Lewis' multiple belts in 2003.
'Dr. Ironfist' rebounded from the Lewis defeat by finishing Kirk Johnson in the second round at Madison Square Garden before dethroning Sanders, only for a severe injury to his anterior cruciate ligament ahead of a second defence against Hasim Rahman to provoke an initial retirement in late 2005.
In 2008, with brother Wladimir having established himself as the dominant force in the heavyweight division, Vitali made a comeback by regaining the WBC crown from Samuel Peter and making nine defences.
This year, Klitschko defeated Britain's Dereck Chisora by unanimous decision in a controversial fight which saw 'Del Boy' provoke both Klitschko brothers before the fight and spark a press conference brawl with David Haye afterward.
And most recently, Klitschko stopped the then-undefeated Manuel Charr in four rounds after busting the German open.
