The developed countries' agenda of carbon barrier policies has significantly accelerated in recent years, with essence to gain the dominance of addressing global climate change and the right to formulate international trade rules, so as to affect the global industrial structure and division of labor. The latest progresses of the EU Carbon Border Adjustment Mechanism (CBAM), the Circular Economy Action Plan (CEAP), EU Battery Law and US Clean Competition Act (CCA) are reviewed in this paper. International carbon barriers will bring Chian a series of negative impacts including hindering the development of the export trade system, increasing the export costs, and increasing the risk of industrial intelligence exposure. The main problems include lack of coping mechanism, insufficient institutional policy and technical standards, weak awareness of barriers, and poor synergy from various supports. In view of these, we put forward countermeasures and governance suggestions:building comprehensive policies scheme for tackling carbon barriers, promoting multilateral climate consultation mechanisms, improving the carbon accounting certification standard system, improving Chinese carbon emission trading market mechanism, reshaping the green and low-carbon industrial supply chain, and strengthening financial and technical service supports.
