Statement delivered by His Excellency General Prayut Chan-o-cha (ret.) Prime Minister of the Kingdom of Thailand on behalf of the Group of 77 and China at the Plenary of the High-level Meeting on Antimicrobial Resistance 21 September 2016, New York
… we must support, as a matter of urgency, research and development of antimicrobials, especially new antibiotics, vaccines, diagnostic tools and innovation, including in traditional and herbal medicine. This must be done while ensuring that R&D efforts are needs-driven, evidence-based, and a shared responsibility. These efforts must be guided by the core principles of affordability, effectiveness, efficiency, and equity through delinking research and development costs from prices and sales volume. The Group of 77 and China is pleased to see this delinkage principle underlined in the Political Declaration.
