As a result of this, it could be thought an extra tournament will be utilised from next year especially with Hearn saying about the big TV contract they have.
He added that it is a big country to conquer and as a result it will not be easy for him. Hearn also said that he has aspirations for Scandanavia as well as China and that the invitational events in the World Series have to grow eventually to become open events which is the next step.
"I think we're going to make an announcement quite soon," Hearn told Live Darts.
"There's going to be some interesting developments in America because we've got a big TV contract there.
"It's a big country to conquer, it's not going to be easy."
He added: "I'm also looking at Scandanavia, I think there's a market out there.
"Again we're looking at bringing something back in China because potentially it's a big market.
"The World Series is a media platform for us where we take the best players in the world against local players, put it on TV and try and spread the game.
"It's working but it's an evolution. Over a period of time, those invitational events have at one time got to become open events, that's the transition.
"It worked well in snooker, we did exactly the same thing in the 80s. In China for example, we took eight players who played eight Chinese players and today China is 40 per cent of our market.
"I don't see why that can't be the case for darts as well."
