Foreign Minister Hina Rabbani Khar Tuesday said the neighbouring countries should have only supportive role in ensuring peace, security and territorial integrity of Afghanistan and the Istanbul Regional Conference would help further this cherished objective. Talking to Pakistan's state news agency in Istanbul where she would represent the country at the Istanbul Regional Conference Wednesday, Khar said the meeting is being attended by immediate and extended neighbours of Afghanistan and important countries of the world with stakes in that country. The foreign minister said the conference would lead up to different peace processes including Bonn Conference on Afghanistan next month and Chicago conference. She expressed the confidence that the conference would give confidence to Afghanistan that all important players are supporting its initiatives for peace and stability.
