It has brought the negative effects to the sustainable development on global society, economy and ecology, which is also one of the main objectives of international cooperation to combat with. At present, subjects of international law play a decisive role in combating illegal logging and related trade. The subjects of international law generally refer to states, intergovernmental organizations (IGOs) and part of non-governmental organizations (NGOs), which can have an independent international legal personality, enjoy rights and assume obligations of international law. As a responsible big country of the international community and state member of intergovernmental organizations and international treaties of forest resources protection, China ought to fully perform the obligations of international law. In face of illegal logging and related trade around the world, China should rationally tackle with it, resolutely crack down on it, and finally choose the sustainable development strategy based on rule of law.展开更多
