Sources in the PCB said the Board was still waiting for a response from the BCB on the last letter sent to them, urging them to file an appeal to the stay order.
"We really don't know what is happening because in our last letter we had made it clear that we feel that the stay order given by the Dhaka High Court against Bangladesh touring Pakistan can be vacated," one PCB source said.
He said the PCB had requested the BCB to keep it updated and share details of any appeal it filed against the writ petition in the Dhaka High Court.
But the BCB has not made any contact with the PCB on the issue and it appeared as if the Bangladesh team's tour was now a thing of the past, the source said.
The Bangladesh team's scheduled tour of Pakistan later this month was postponed last week after some citizens and former players filed a writ petition in the Dhaka High Court insisting it was not safe for the Bangladesh team to tour Pakistan.
