Laporta was previously Barca president between 2003 and 2010, a spell that included hiring Guardiola to be head coach in 2008, starting an extraordinary run of success.
"All I can say is that it was a lovely journey," said Guardiola when he was asked about Barca's election.
"All three options were there, they did a good job and I congratulate the president to be elected by a big margin.
"I'm pretty sure his personality will introduce a good mood, a lot of optimism in the club and all the country.
"I wish him all the best for the season and the next seasons."
