"Khan is scheduled to meet Singh on Tuesday and will seek his help for the timely approval of the proposed itinerary", local media quoted PCB officials as saying.
Natwar Singh, who arrives here today on four-day visit, would hold talks with President Pervez Musharraf and other top Pakistan leaders.
The Indian Cricket Board (BCCI) has already approved the schedule and sent it to the government for approval. The Indian team is due in Pakistan in January next to play three Tests and five One-day internationals.
Both Khan and Singh are good friends and Singh could play a crucial role in getting the approval in time for PCB to make preparations, local daily The News quoted PCB officials as saying.
Singh had met with Khan during his visit to Islamabad earlier this year to resolve the impasse over whether Pakistan should play in Ahemdabad or not during the team's tour to India.
