We make constant efforts to seek international opportunities in strategic cooperation, product introduction and joint venture cooperation to rapidly enrich and optimize our product portfolios. Over the past one year, more than 30 newly launched innovative drugs have been introduced, and the acquisition rate of bulk-buying varieties exceeded 60%. At the same time, we actively cultivated our capabilities in port import services and registration inspection. In 2021, we established the Hainan port business, thus enhancing exchanges and cooperation with high-quality international partners, and strengthening the introduction of imported varieties. The annual sales of imported products amounted to approximately RMB 12.7 billion, and 17 new products were introduced (including the import and distribution rights of three varieties of medicines, seven varieties of equipment and five varieties of healthcare). We also established cooperation with Mitsui in cross-border e-commerce to continuously promote the development of international business.
At the same time, we also vigorously promote the specialized development of the medical device distribution business, and strive to build a specialized device headquarters. We have established independent medical device companies in 17 provinces with a focus on the development of professional product lines and service models, and focus on the development of intervention, IVD diagnostic reagents, orthopedics, equipment, comprehensive consumables and other product lines.
