Nasser Al-Khelaifi has refuted speculation linking two of the club's prized assets with a switch away from the French capital this summer.
The former AC Milan duo have each been linked with a switch away from Parc des Princes this summer, some 12 months after their big-money moves from the Rossoneri.
Earlier on Thursday newly appointed PSG boss Laurent Blanc confirmed the club would be retaining the services of Ibrahimovic, and president Al-Khelafi echoed those sentiments while also denying Silva's proposed departure.
He told a press conference: "I read lots of speculation in the press about them leaving, but I can confirm that Thiago Silva and Zlatan Ibrahimovic will stay here until the end of their contracts."
Liga giant Barcelona are reportedly keen on luring the Brazil international, Thiago to Camp Nou during the off-season, while a number of clubs in Italy are said to have registered an interest in signing the Swede.
Both have proved valuable additions to les Parisiens ranks and played a pivotal role in the club ending its 19-year wait for a league title last season, with Ibrahimovic netting 30 times en route to Ligue 1 glory.
Ibrahimovic has a contract until June 2015. Thiago's deal expires in the summer of 2017.
