(Thailand’s Private Sector Collective Action Coalition Against Corruption: CAC)

GC has consistently prioritised the implementation of anti-corruption and anti-bribery measures across both the public and private sectors, and has demonstrated a clear commitment to combating corruption in all forms. In 2025, the company is in the process of renewing its membership certification with the Thai Private Sector Collective Action Against Corruption (CAC) for the fourth consecutive time.

Furthermore, the company actively encourages its subsidiaries, business partners, and allies to develop their own anti-corruption systems by inviting them to declare their intent with CAC, in order to build a transparent and sustainable supply chain. As a result, the company has received the CAC Change Agent Award for four consecutive years. The company also consistently cooperates and participates in anti-corruption activities organised by the government, the National Anti-Corruption Commission (NACC), the Office of the Public Sector Anti-Corruption Commission (PACC), the Anti-Corruption Organisation of Thailand (ACT), and all sectoral network partners.

The company strictly prohibits bribery and all forms of corruption, including politically related donations and lobbying activities, as part of its anti-corruption policy. In 2025, the company made no donations, political campaign expenditures, or contributions to any political organisations, nor engaged in any lobbying within organisations, trade associations, or other tax-exempt groups.

GC developed the Hook E-Learning system in various languages, including English, to enable executives and employees at all levels of GC Group and subsidiaries to equally enable their learning and understanding of contents related to Corporate Governance (CG) and GC Group Code of Conduct. Additionally, it also acts as another platform to evaluate the participant's understanding. The participants will be required to sign the acknowledgement that represents the commitment and the deployment of CG and corporate compliance policies. The evaluation result will also be used for the improvement of knowledge-sharing and training next years.
