The Pakistan-Turkey-Afghanistan summit at Istanbul which concluded on Tuesday, the 6th in the series held in search of a durable solution to the Afghanistan tangle, reached certain vital and far-reaching decisions. The three leaders, Presidents Asif Zardari, Hamid Karzai and Abdullah Gul who hosted the meeting, discussed the pros and cons of the various options to restore peace and security to the troubled land and the region. A regional solution by building a comprehensive partnership between the three countries was what they believed held the key. In this context, the three Presidents discussed the possibility of constituting a commission of Foreign Ministers to identify the regions problems and prepare a programme of action to resolve them. To quote Mr Zardari, We have also agreed to strengthen regional economic cooperation through this important trilateral process. It was good to see the three countries sign an MoU on Conduct of Mutual Exercises and Training Courses among their armed forces. In addition, their Interior Ministers signed a protocol for this training cooperation. Besides, yet another irritant that had recently erupted between Kabul and Islamabad, adding to the quite a few already existing, was debated and the stage was set for its removal. The Afghan accusation that Pakistan has been responsible for assassinating former President of Afghanistan, Prof Burhanuddin Rabbani has already been vehemently denied. The two countries further agreed to evolve a cooperation mechanism to investigate the matter further. The murder particularly disturbed Afghan leadership. President Rabbani was also the leading figure involved in an exercise to persuade the Taliban to sit on the negotiating table to settle contentious issues to make for an honourable exit of the foreign troops. Hopefully, as the truth behind the death comes out, it would help dissipate the clouds of distrust between Pakistan and Afghanistan and create the realisation that it is in the interest of both countries and the region as a whole to develop a relationship of deep and sincere understanding. During the conference, Pakistan and Turkey signed an agreement for currency swap that would help greatly boost trade between them, as it would allow businessmen and the trading community to do trade in local currencies. Presently, the bilateral trade hovers between $800 million and $900 million, but is billed to touch $2 billion this year. The agreement would also make for greater interaction among the people of both countries through travel and tourism. President Zardari and President Gul took another landmark decision about upgrading the existing Islamabad-Ankara railway track, and later laying a new one. That would promote not only commercial relations, but also interaction at the peoples level.
