Pakistan President Pervez Musharraf will travel to Afghanistan next week for talks with his counterpart Hamid Karzai.
However, no dates were given for Musharraf's trip because of security concerns, Dawn said.
"I can only say that this visit is planned, but we cannot release any other details because of security reasons," said an official.
Foreign Ministry spokeswoman Tasnim Aslam confirmed that the president's visit had been planned, but gave no further details.
It was not clear whether the visit was connected with the killing of Baloch leader Akbar Bugti in a military operation last week.
Balochistan shares a 1,173 km border with Iran and 837 km border with Afghanistan's volatile southern region.
There were reports from Kabul that the Afghan parliamentarians condemned Bugti's killing and on Monday there were attempts to move a strongly worded resolution.
Aslam, when asked, said she had not seen the reports.
The Karzai government issued a guarded statement regretting Bugti's killing and praising him as a prominent Baloch leader.
Pakistan and Afghanistan have been involved in frequent diplomatic spats, at the highest level, with the latter alleging that the Taliban were using Pakistani territory to stage attacks on Kabul's forces, a charge Islamabad has denied.
