It was the 36-year-old's ninth victory in a row Saturday and he has improved his record to 22-1, reports Xinhua.
Stevenson, a southpaw, was the home favourite after defending his world title by knocking out American Chad Dawson in only 76 seconds in June.
"I've beaten two great champions," Stevenson said.
"Just basic boxing, connecting, using my jab, my movement. I was training for that. I've been in seven rounds, I still can box him."
