APEC, in addition to other regional and multilateral fora, has a renewed focus on supply chain issues in response to COVID-19 and other economic and environmental factors. Chemicals are critical inputs to most key supply chains. The chemical markets of APEC account 70% of world demand for chemistry, but their relevance and importance is often not well understood, nor is how supply chain initiatives for end products or raw materials can affect APEC chemical production, trade, or investment. This project will map out chemistries that are used in key supply chains (using specific product examples) and the different types of supply chain initiatives that may affect such chemistries. A capacity building workshop will be organized to bring together governments, industry, and other stakeholders to better understand the role of chemicals as part of larger value/supply chains and identify potential trade facilitative measures that can best promote sustainable and resilient supply chains involving chemicals.
