Hammad Azhar, a former finance minister under Khan, who attended the meeting virtually, said in a post on Twitter that the former premier and his economic team had discussed last week's staff-level deal between the IMF and Pakistan's government.
The new deal, which will be vital to help stabilise Pakistan's struggling $350 billion economy, will be taken up for approval by the IMF board on July 12.
Khan's government deviated from agreements under an earlier IMF programme days before he was ousted in a parliamentary vote last year, leading to a delay in the implementation of the programme and increased economic uncertainty.
The meeting is the highest profile engagement for Khan and his the PTI since he was ousted from power less than four years into his five-year term.
Many of Khan's key aides remain under arrest and many others, like Azhar, are in hiding.
