The 2012 Champions League winners last toured Asia in 2011 ahead of the season which secured the European Cup for the first time, as well as the FA Cup.
It is uncertain who will be the Chelsea manager for the trip, with Rafael Benitez's contract as interim boss ending at the end of the current season amid rumours of a Stamford Bridge return for Jose Mourinho, currently in charge at Real Madrid.
On July 17, the Blues will play a Singha Thailand All-Star XI in the Singha Cup at the Rajamangala National Stadium in Bangkok.
A fixture with a Malaysia XI at the Shah Alam Stadium in Kuala Lumpur follows four days later.
Chelsea then play in Indonesia for the first time, on July 25, against an Indonesia XI at Jakarta's 88,000-seater Gelora Bung Karno Stadium.
Chief executive Ron Gourlay said on chelseafc.com: "It is fantastic that we will be returning to Asia for what promises to be an excellent pre-season tour.
"South-east Asia remains home to an ever-growing and passionate Chelsea FC support and it gives me great pleasure that we will again be able to experience that wonderful hospitality.
"In particular I look forward to visiting Indonesia for the first time, a country where we have an extensive fan base that is eager to see Chelsea play.
"I am sure we will face strong opposition in packed stadiums as we celebrate the successes of some of our important regional partners, and we will once again leave an important legacy in terms of the community work we conduct during the tour and for long afterwards."
