Blatche, June Mar Fajardo, Jayson Castro, Gabe Norwood, and Paul Lee were all on the team that played in the 2014 FIBA World Cup in Seville, Spain.
"We now have the experience in the World Cup now," Blatche said on SportsCenter. "Each game [in 2014] came down to a couple of possessions in the fourth quarter. Now, we got to learn from our mistakes. Jayson is now a super veteran, same with Gabe.
This year, if we're in the same situation, we know what to do to get that necessary stop and necessary points."
Blatche would welcome the chance to play alongside Cleveland Cavaliers guard Jordan Clarkson if Clarkson is cleared by FIBA to play.
"[Having Clarkson] will be huge if we can definitely get him ...me and him together, we're definitely got to make some noise," said Blatche.
Blatche is returning to China to resume playing for the Tianjin Gold Lions in the Chinese Basketball Association.
Blatche would not say whether he would play for the PBA as an import leading up to the World Cup.
Samahang Basketbol ng Pilipinas officials are talking to FIBA about Clarkson's eligibility.
Clarkson played for Gilas for the first time in the 2018 Jakarta Asian Games as a naturalized player after being given a one-time exemption by the NBA.
