Kong said China had been dealing with its development issues through its own efforts while learning from Japan's experience and lessons at the same time since the beginning of the reform and opening-up, however, after 40 years of development, China also had its cutting-edge areas.

"In some areas, China has already surpassed Japan. Both sides should strive to adapt to this change and learn from each other to achieve common development," he said.
