The Brazilian star has constantly been linked with a move to the Catalan giants, as well as their La Liga rivals Real Madrid, and reports on Tuesday had suggested he had agreed personal terms ahead of a move to the Nou Camp next summer.
While admitting that Santos have been in contact with both Barca and Madrid, Ribeiro has insisted that they have no intention of selling their star asset, who is tied down to a long contract with his boyhood club.
Ribeiro said: "That means nothing, there is nothing denied yet and we will fight to keep Neymar. Neymar is happy, he is playing well and more importantly, he is paid very well.
"People have to convince themselves that Neymar will stay and that will happen for an obvious reason. If he stays until the end of his contract, any money involved in an eventual negotiation will be Neymar's. If Santos sell him before that, Santos will get that money.
"Santos don't need to sell players. Our cash flow doesn't include money from selling players. Santos are a club and as such have the objective of winning titles. And Neymar is the player that gives us more chances of achieving that."
Neymar has been capped 23 times by Brazil at senior level, scoring 13 times.
