EU’ legislation on electricity infrastructure lacks specific legislation for electricity infrastructure and simplifies environmental assessment procedures. Meanwhile, it lacks supports for the integration of renewable energy into electricity infrastructure and has imperfect issues on information exchange mechanisms. Therefore, in the process of implementing global energy interconnection initiative, it should focus on the protection of electricity infrastructure on macro-law and carry out multi-level electricity interconnection with multi-level platforms of policy dialogue. China's domestic legislation and strategic planning should attach importance on cross-border factors and actively participate in global energy governance.
