Pakistan's Prime Minister Shaukat Aziz flew back home after his four-day visit to Turkey Friday night and described his trip as 'highly productive.' "The visit would further enhance the excellent relations between the two countries in all areas including trade, economy and defense," Aziz told the reporters on return. "We held wide-ranging and productive talks with the Turkish leadership and the two sides have identity of views on all major regional and international issues," the prime minister said. Aziz expressed the hope that his discussion with the Turkish leadership and interaction with the private sector will lead to a higher level of Turkish investment in Pakistan, besides improving the two-way trade. The prime minister said Turkish President Ahmet Necdet Sezer will be visiting Pakistan next week and it would provide an opportunity to take the process of close interaction on major issues forward.
