No hate from me.
I completely believe that PAF officers were present to list their needs and also what's written here:
Learning and cooperation is a more effective way to improve working thoughts and methods. During the implementation of the JF-17/FC-1 program, China has sent out numerous experts to assist the PAF with manufacturing and staff training. Now, the manufacturing base for the 3rd generation fighter has been established in Pakistan and the airframe and main avionics equipment of the JF-17/FC-1 can be assembled, tested, and manufactured in Pakistan. Therefore, the Pakistani people have realized their dream of being able to produce modern aviation products.
Meanwhile, plenty of Pakistani engineers and technicians have come to China for work and study. The AVIC-PAF Officer Development Program (APOD) has trained many high-level officials from the PAF. Those officials from the headquarters, military bases and combat troops of the PAF come to learn the most advanced aviation technology and modern enterprise management concepts. Their visits to the first-class aviation enterprises and research institutions help them gain insight into the development of China’s aviation industry and China’s profound culture. The study and visits also enhance the PAF’s confidence and capabilities in practice, as well as the mutual understanding between CATIC and the PAF. This cooperative mode is strengthened and improved with the process of constant exchange and communication.
