The 25-year-old Spain international played 40 times for Barca in all competitions last season, scoring seven goals.
However, he may see his opportunities limited at Camp Nou next campaign following the arrival of Brazilian superstar Neymar from Santos.
Pedro, who has been at Barca since the age of 17, has always indicated he is happy to stay at the club.
Speaking at a press conference in Brazil ahead of Spain's Confederations Cup opener with Uruguay on Sunday, Pedro again said of his future: "There is nothing at the moment, I am calm.
"I trust this club, my team-mates and I hope to stay for a long time."
When quizzed on his new club mate Neymar, who he could also face at the Confederations Cup, he added: "[Neymar] is one of the best players in the world nowadays and as I have always said, the best deserve to be at Barcelona.
"It will be a pleasure to have him with us and I hope he can show all of his talent."
