Core Viewpoint - The article emphasizes the need for deeper cooperation between China and the EU in light of the uncertain international political and economic landscape, particularly focusing on fair trade rules and maximizing the benefits of the Carbon Border Adjustment Mechanism (CBAM) for sustainable development [1][6]. Summary by Relevant Sections Potential Impact of EU CBAM - The EU's CBAM may lead to increased costs for certain member states, with significant disparities in impact, particularly affecting countries like Bulgaria, Ireland, and Greece that rely heavily on imports from non-EU countries [2]. - For China, the short-term effects of CBAM are limited, but the long-term implications are substantial, as the mechanism initially targets industries like steel and aluminum, which are significant in China's exports to the EU [2]. Opportunities and Challenges in China-EU Economic Cooperation - China and the EU share a consistent stance on climate action, which can be leveraged to enhance cooperation in clean energy projects under the Belt and Road Initiative, focusing on nuclear, wind, and solar energy [3]. - The challenges posed by CBAM include its role as a tool for achieving climate goals, which may restrict trade flexibility and highlight differences in resource endowments and development stages between China and the EU [4]. Development Directions for China-EU Economic Cooperation - Strengthening policy dialogue and coordinating carbon pricing mechanisms is essential to reduce friction caused by climate policies, with suggestions for regular discussions on carbon pricing and CBAM implementation details [7]. - Improving the carbon emission accounting system to enhance data credibility and accuracy is crucial, with proposals for unified standards and data sharing to mitigate uncertainties in CBAM implementation [8]. - Exploring mechanisms for redistributing CBAM revenues to support low-carbon transitions in developing countries can help alleviate the impact of CBAM on global trade dynamics [9]. - Promoting green technology cooperation is vital, leveraging China's strengths in clean energy and the EU's comprehensive green governance framework to enhance low-carbon industrial development [9].
