Interior minister Nisar Ali Khan addressing a press conference here said that western countries were misusing the agreement and deporting Pakistani citizens "without verification".
He said under readmission agreements Pakistanis travelling illegally to any western country have to be deported after proper verification.
"At least 90,000 people were sent back to Pakistan during the last year," he said.
Khan said that there was a general trend that Pakistanis travelling abroad without documents are deported on charges of terrorism without verification.
