"Some fans took my picture and it's unfair that I am being used by anyone to say that I am showing support for the demonstrators," he wrote on his Facebook page.
"I am not supporting the demonstrators as I don't really know anything about the situation and my impromptu visit to the site was just part of an innocent walk around Hong Kong."
He added: "I love China and love coming here to perform for over 25 years. I only wanted to share my wish for peace for Hong Kong and for all of China".
