Executive Summary UN Human Rights Council provides a framework for business and human rights on 3 pillars: 1. Protect – Government has a duty to protect against human rights violation from the third party 2. Respect – Business has a duty to respect human rights 3. Remedy – victim of human rights violation should be able to access a remedy process in the forms of either justice system or non-justice system such as a conciliation process. Due to the fact that the framework gives two primary duties for the Government to proceed: Pillar 1 (protect) and Pillar 3 (remedy).

National Human Rights Commission of Thailand (NHRC) understands the need and has provided the funding for this research on “National Baseline Assessment on Business and Human Rights: Policy, Law and Measure related to investment of Thailand,” in order to achieve full understandings of the gaps of those policy, law and measure with respect to the two pillars of the UNGP (pillar 1, protect; and pillar 3, remedy). The NHRC can use the knowledge obtained by this study to observe current business and human rights-related issues, to monitor present and forthcoming situation of business and human rights, and to provide the support on business and human rights protect and remedy systems. This research uses a Gap analysis approach to assess the gap between the actual protect and remedy system (policy, law and measure) and the desired protect and remedy system that lead to policy recommendations. Due to the fact that Thailand has too many rules and regulations involved (for example, the number of current rules and regulations is higher than 100,000, which prevents the gap anaylsis on every rules and regulations that are in place), this research aims to support the NHRC in evaluating the progress of the implementation of the National Action Plan on Business and Human Rights (NAPs). By focusing on the current important issues through five criteria that narrow down the issue: 1) high frequency issues 2) high impact I
