Besson singled out two unnamed agencies from Hong Kong for special condemnation, but labeled as incorrect press reports that he wanted to leave Taiwan early to register his disapproval of their actions.
"I read in the newspaper that I was ready to leave," he said. "This is wrong."
Besson also said it was incorrect to say that drug smuggling was the focus of the film, saying it comprised only a very small part.
"The film is about pure intelligence," he said, declining to elaborate. "We're basically using 10 percent of our brain. What happens when we use more?"
Besson said work on the film would take another year, and that it was still too early to talk about a release date.
