Pakistan and Iran signed a Memorandum of Understanding on Sunday to improve the situation at the border between the two countries, Radio Pakistan reported.

During the 21st two-day meeting of the Pak-Iran Joint Border Commission in Gwadar, joint proposals regarding the border situation, security matters, immigration and border trade between two countries came under discussion, the state-run daily added.

Both sides expressed their determination to prevent the smuggling of drugs, intrusion of illegal immigrants and the use of their respective soils for terrorism, Radio Pakistan said.

Provincial Chief Secretary Aurangzeb Haque led the Pakistani side while Deputy Governor Sistan-Balochistan province Ali Asghar Mir Shikari headed the Iranian delegation in the meeting.

Last month, Prime Minister Shahid Khaqan Abbasi and Iranian President Muhammad Hassan Rouhani met on the sidelines of the 72nd session of the United Nations General Assembly in New York. Both sides agreed to "maintain a trajectory of positive progress" between the two countries.

President Rouhani was said to have emphasised that the two countries should work together closely in deepening mutual cooperation in the areas of border management, trade and investment.
