High-level visits

Former Pakistani officials also often visit China.

"Such visits are not made out of political obligation but are driven by Pakistanis' great affinity to China. Pakistanis respect China's achievements, which have improved the quality of life of its people," Aziz said.

The nations' multilevel communication is the basis of the friendship in various areas, and constant dialogue at different levels is the basis of a good relationship, Aziz said.

While Pakistan develops its relations with many other countries, the priority of the Sino-Pakistani friendship will not be influenced, he added.

Islamabad has taken measures to deal with the Taliban and terrorism, Aziz said, referring to the Taliban's recent terrorist attack in Pakistan's northern Gilgit-Baltistan area in which 11 people were killed, including two Chinese nationals and a Chinese-American.

"It was unfortunate," Aziz said. "It was not against any specific country and should not affect bilateral relations."
