"Turkey and Pakistan are like one soul in two hearts," Sharif told Anadolu Agency during his visit to Turkey's central Kayseri province on Sunday.
Sharif said Turkey and Pakistan have been consulting each other "very frequently,” citing the visit by Turkish President Recep Tayyip Erdogan last month and his address to the parliament.
"In his speech, he made it very clear that Kashmir has to be resolved on the basis of equity and fair play. He also mentioned our brotherhood."
About Turkish investments in Pakistan, Sharif said they are on the rise, particularly in Punjab, home to about half of Pakistan’s population.
Sharif said there are many Turkish companies operating in the country, which is leading to a "closer" bilateral relationship.
But as for the bilateral trade volume, currently less than $1 billion, he urged: "We have to enhance it."
"I hope that by the end of this month, a free trade agreement would be finalized between our two countries," he added.
