2019 is the 70th anniversary of the founding of the People’s Republic of China. Besides the promotion of solutions in domestic ecological and environmental problems，China actively participates in international cooperation and global environmental governance. China has further improved its ecological civilization system，vigorously promoted the construction of the Green Belt and Road Initiative，and actively built an international environmental law discourse system. Certain theoretical breakthroughs have also been made in research on specific areas such as climate change，biodiversity protection，and marine pollution. In general，the theories proposed by the international environmental law research need to further focus on the innovation and enlightenment of research results，increase the practice of international environmental law，and improve the theoretical system of international environmental law with Chinese characteristics. Promoting the consolidation of basic theories of international environmental law still requires the unremitting efforts of the academic community.
