Barca's corporate director general Joan Oliver said: "Cesc has arrived in South Africa for the World Cup, but there are a lot of football people there.
"Arsenal manager Arsene Wenger and Barca representatives will be there."
Oliver believes a deal can be done to bring the Spain international, who played in the youth team at the Nou Camp before moving to north London seven years ago, back to Barcelona, although he would not be drawn into when the transfer could happen.
"You can never predict when a signing will be closed," he said. "In this world, when you put a deadline on it, you always end up losing out.
"This is a three-sided affair and the third side [Arsenal] have not expressed themselves in any way.
Would you keep Fabregas or do a swap deal with Barca for Ibrahimovic? leicestertigerfox "There is a player who wants to come here, but he has a contract. We have made an offer and they have said that the player is not for sale.
"The problem is between the player and the club [Arsenal]; we haven't been invited to the table [to negotiate]."
Oliver also dismissed Real Madrid's interest in Fabregas, suggesting that Arsenal are using their Spanish rivals to bump up the price.
"What a coincidence," he said. "When Barca are negotiating for a player, another club appears out of the blue - it's always the same.
"We complete signings when the price is reasonable. And the story of Cesc is what it is. The player has said both publicly and privately that he wants to play for Barca."
