In 2022, THSRC established relationships with 696 suppliers, 463 of whom provide materials, mainly equipment parts and vehicle products, and 233 of whom provide labor. To achieve our sustainability goals, we have developed "Procurement Regulations." Sustainability is comprehensively evaluated through the management manual and precautions taken before signing off on instructions. Any supplier who violates these regulations and refuses to rectify the situation within the specified period will have their cooperation terminated. In 2022, there was no cooperation terminated due to vendors' poor ESG performance.
Additionally, since 2019, bidders have been required to commit to cooperating with THSRC's CSR regulations and sign a CSR commitment. Regular project group meetings are held to review the self-assessment forms of contractors. As of September 30, 2023, we had collected a total of 1,059 corporate social responsibility commitments and 399 corporate social responsibility commitment self-assessment forms. We had completed 14 on-site inspection of suppliers, and according to the inspection results, there were no defect records.
