O'Sullivan won his fourth world title at the Crucible in Sheffield on Monday when he beat fellow-Briton Ali Carter 18-11 in the final.
"If China want it, they can have it," O'Suillivan told reporters. "They're the most powerful country in the world. One day this tournament will be in China, have no doubts about that.
"I love going to China and the Chinese people. I love the food and I love the culture."
Sheffield has held the world championship tournament since 1977.
O'Sullivan's comments are in contrast to the views expressed by World Snooker chairman Barry Hearn.
At the start of the tournament, he vowed to keep it at the Crucible "until the day I die".
