ANKARA (Agencies) - Pakistan and Turkey on Tuesday vowed to further strengthen their bilateral relations in defence, energy commerce and communication sectors and set up a target to raise annual bilateral trade to US one billion dollars. Prime Minister of Turkey Recep Tayyip Erdogan and Prime Minister Syed Yousuf Raza Gilani held formal talks here and pledged to further strengthen their brotherly relations by exploring new avenues of cooperation. The two prime ministers initially held half an hour one-on-one meeting, which was followed by delegation level talks that lasted for over an hour. Addressing a joint Press conference after the talks, the Turkish Prime Minister said his country was ready to extend full cooperation and assistance to Pakistan to come out of its current economic crisis and enhance development in the country. Erdogan said trade and economic activities would be enhanced further so as to boost the volume of trade for the benefit of the two countries. The two countries also agreed to enhance their bilateral relations in trade, economic, defence and communication sectors. The Turkish Premier appreciated Pakistan's role in the war against terror and urged the international community to extend full cooperation to Pakistan. He said Turkey will also provide more assistance to Pakistan in defence sector and has already offered to provide expertise in F-16 upgradation and joint production of 973 GMC trucks that would be later expanded. The Turkish leader said they had submitted a bid in a Pakistani tender to modernise the country's F-16 fighter jet fleet. He said more joint ventures in defence production were being discussed at the highest level. The two sides are also working on a defense agreement, Erdogan said without providing details. Erdogan said trilateral summit of leaders of Pakistan, Turkey and Afghanistan will be held in Turkey very soon to ensure peace and security in the region. He said Turkey will be happy to play an important role in resolving the conflict in the region so that there would be peace and security. In April 2007, Ankara hosted fence-mending talks between then Pakistani president Pervez Musharraf and his Afghan counterpart Hamid Karzai, in which the two leaders agreed to step up joint efforts against terrorism and boost confidence-building. He said global cooperation is must to fight terrorism and extremism and added that Pakistan should not be left alone in this struggle. A second summit is being planned, but no firm date has yet been set, Erdogan said. "We have sent alternative dates to the parties. We are expecting their response," he said. About economic cooperation, he assured that Turkey would provide full help and cooperation to Pakistan. Gilani expressed his appreciation to the government of Turkey for inviting him to Turkey's National Day celebrations. He said both countries have unanimity of views on all issues and the cooperation between the two countries would be further enhanced following this visit. Gilani said the two sides discussed the regional situation and he particularly mentioned Pakistan's efforts to ensure stability in Afghanistan and the region. Gilani, who arrived late Monday on a five-day visit, was scheduled to meet President Abdullah Gul and Parliament Speaker Koksal Toptan later in the day. The Pakistani leader was also to attend a state ceremony Wednesday to mark Turkey's Republic Day, October 29, before travelling on to Istanbul for an international conference organised by the World Economic Forum. Turkey has had traditionally warm ties with Pakistan since the South Asian nation's independence more than 60 years ago, with the countries often running cultural exchange programmes.
