The Indonesian businessman bought the club from long-standing owner Massimo Moratti back in October as the Nerazzurri look to rebuild after a few unstable seasons.
However, he has said that Inter remain a work in progress and that a fourth-placed finish remains their target for the current season.
"Compared to last season the team has improved," he told Indonesian newspaper Republika.
"But the target remains fourth and I think that's plausible for us this season. I urge the fans to be patient – a business is not built in a few months. We're going to have to wait a few years.
"You only have to look at the model franchise in America to see that."
Inter, who are currently fifth in Serie A, travel to Genoa on Sunday.
