A PCB official confirmed that Pakistan was due to play two Tests, three ODIs and two Twenty20 matches in Zimbabwe at the end of the year.
"But we have now asked them to postpone this to next year as the dates clash with the Indian tour. We tried to adjust the series in November but at that time the Zimbabwe Cricket Union has some issues," the official said.
Pakistan is due to tour India in late December to play three ODIs and two T20 matches and the series is being given lot of importance as it will herald the revival of bilateral cricket ties between the two nations after 2007.
The official insisted that Pakistan was keen to support Zimbabwe cricket and had invited them regularly to play here.
"But unfortunately this time we are facing problems in creating a proper window because immediately after the Indian tour, we also have a full tour to South Africa," he said.
He said Pakistan had no intention of cancelling the tour but only wanted it moved to next year. Pakistan's last tour to Zimbabwe happened last year.
