Abstract: As the key content of the "Convention on Biological Diversity" and "Aichi Target", the protection of cross-border biodiversity areas has become a frontier field of environmental governance in the international society. For the purpose of responding to ecological needs, fulfilling the obligations of the Convention on Biological Diversity and adhering to the concept of a community with a shared future for mankind, China adheres to the exploration of cross-border regional protection of biodiversity, promotes the construction of international rule systems in this field, forms a multi-level cooperation governance organization structure and produce special cooperation mechanisms for joint law enforcement, information exchange, and cooperative management. These have achieved certain results in practice. It is still far away from forming a regional consensus or even a global resolution for China's experience in cross-border biodiversity conservation. First, it is due to the the external constraints such as unwillingness and insufficient capability of cooperation of some nations. Second, it is because of the internal operational defects such as the lack of legal basis, the lack of linkage in cooperation structure, and the narrow scope of coordination. It is essential to grasp the foundation of multiple parties’ interests and help other nations improve their capability to overcome external obstacles. Focus on supplementing the legal and regulatory system, formulating an overall national strategic plan, and expanding the scope of cooperative protection to optimize the existing plan, so as to promote the further development of China's practice of cross-border protection of biodiversity.

Key words: Convention on biological diversity, Aichi Targets, biodiversity, transboundary protection
