He made the remarks at the renaming of Southern Boulevard to Donald J Trump Boulevard in Washington on Friday.
"In a year, we made eight peace deals and ended the conflict in Gaza. We have peace in the Middle East...We stopped India and Pakistan from fighting, two nuclear nations...The Pakistani Prime Minister said Donald Trump saved at least 10 million people, and it was amazing," he said.
The US president further recalled that the Pakistani prime minister’s remarks were an honour for him.
Trump cited his administration’s foreign policy record and repeated assertions of brokering peace between the two nuclear-armed neighbours.
Trump has made similar claims multiple times since May 10 last year, arguing that US pressure helped defuse tensions between India and Pakistan.
