"I'm a huge fan of Star Wars, Empire and Jedi, and the idea of the world continuing is exciting and will be amazing," he told Empire.
"Kathy Kennedy is a friend and there are no smarter producers. It's in great hands... There were the very early conversations and I quickly said that because of my loyalty to Star Trek, and also just being a fan, I wouldn't even want to be involved in the next version of those things," he continued.
"I declined any involvement very early on. I'd rather be in the audience not knowing what was coming, rather than being involved in the minutiae of making them," he added.
JJ, who has been working on the Star Trek Into Darkness, previously said that he has no plans to make Star Wars one of his enterprises.
"Star Wars is one of my favourite movies of all time. I almost feel that, in a weird way, the opportunity for whomever it is to direct that movie, it comes with the burden of being that kind of iconic movie and series," he told Hollywood Life.
