China is often perceived as a permanent member of the UN Security Council only for prominent individual decisions: Abstention in Libya, Veto in Syria. And yet the Security Council membership is crucial for China's international policy. China considers the Council as a central and stabilizing factor in international relations. Against this background any reform of this institution from a Chinese perspective would imply a fundamental realignment of the global collective security system which would require a broad international consensus. On the whole, China's stance has experienced gradual but serious changes in the past few decades. By now, it provides the largest amount of P5 troops for UN peacekeeping missions, stages the sixth largest contributions, and has strengthened the system of UN peacekeeping in a pragmatic and flexible way, despite inherent caveats in many individual cases.
