| As environmental issues become prominent, currently it is a consensus to stipulate environmental clauses in the international investment agreements for the purpose of balancing the contradiction between investment liberalization and environmental protection. It is of great significance for the introduction and management of foreign investment in China to include Environmental protection clauses which emphasize the importance of environmental protection and recognize the rights for China to adopt reasonable environmental measures in China’s investment agreements. Not only that, when China’s overseas investors encounter environmental risk, environmental clauses on environmental measures influence on China’s overseas investor interests.
