On Tuesday, China issued its eighth defense white paper in 15 years, elaborating its new security concept and providing detailed information on the diversified employment of its armed forces.

As a move to improve its military transparency, the document provides a prism for the outside world to see its defense policy and help others better understand why China is obliged to enhance its military capabilities.

While analyzing the challenges China's armed forces are facing today, the white paper emphasizes the country's pursuit of peaceful development and the country's commitment to a national defense policy that is defensive in nature. It drives home the message that China is fully capable of defending its land and people as well as its growing interests overseas.
