The SCO defense and security cooperation is immersed in the "Shanghai Spirit", which essentially means mutual trust, mutual benefit, equality, consultation, respect for social and political differences and seeking of common development. The "Shanghai Spirit" follows the principle of non-alliance, non-confrontation, non-targeting of other countries and organizations, and openness.

Through defense and security cooperation, the SCO has strengthened unity among its member states, deepened mutual military and security trust, improved members' capability to jointly deal with new challenges and threats, and thus played an important role in safeguarding peace and stability in the region.

China has been taking part in the Asia-Pacific defense dialogue, too, to foster common regional security concepts. Given the regional diversification, and social, political and cultural differences, different countries understand regional security differently, hindering security cooperation in Asia-Pacific.

In recent years, an increasing number of military leaders and experts from China have taken active part in various regional and global military dialogues and conferences such as the Shangri-La Dialogue, the Council for Security Cooperation in the Asia-Pacific Region Dialogue and the Jakarta International Defense Dialogue. And they have used these occasions to introduce China's new security concept featuring mutual trust, mutual benefit, equality and coordination to build a harmonious Asia-Pacific, and to allay fears on the modernization of the Chinese military.

The Xiangshan Forum, sponsored by the PLA, has now grown into a security dialogue with certain international features. By taking the initiative in setting the agenda, the forum can help foreign academics take a more objective view of China and its military development, and increase Sino-foreign military exchanges and deepen mutual understanding and trust.

China has been fulfilling its due international obligations as a responsible power. The country sent its military observers abroad for the first time in 1990, and since then it has contributed 22,000 personnel to 23 UN peacekeeping missions. In fact, China is the largest contributor of troops to UN missions among the five permanent UN Security Council members.

Following the resolutions of the UN Security Council, the PLA Navy has dispatched 17 batches of warships on regular escort missions in the Gulf of Aden and waters off Somalia since 2008 to safeguard the international waterway.

The Chinese military's participation in UN peacekeeping operations and escort missions shows how committed the Chinese government is to world peace. And State Councilor Chang Wanquan's participation in ADMM-Plus will further confirm that commitment.
