On March 6, 2025, the UK-China Industrial Roundtable on CBAM convened in Shanghai—the first bilateral dialogue on the policy. The UK announced CBAM will impose carbon tariffs on imported steel and aluminum starting in 2027, using methodologies distinct from the EU CBAM but still allowing third-country carbon price deductions. Chinese stakeholders raised concerns over data security and historical emission calculations, advocating for phased rule adjustments. Enterprises like Baosteel and CITIC Special Steel stressed the need for tech-driven cost reductions and global carbon market interoperability.
