Page 3 discusses about Supply Chain Standards and the statement asks the Suppliers to comply to Amazon's Supply Chain Standards. However, the statement does not specifically name the suppliers in Amazon's supply chain. The document only says 'Suppliers' throughout the statement. Page 9 specifically mentions Selling Partners, who are "third-party sellers and retail vendors offering products for sale in Amazon's stores (9)." The statement also holds Selling Partners to be accountable for following Supply Chain Standards.

Page 1 of the document defines their areas of operations into three parts: North America, International, and Amazon Web Services (AWS). Although the statement doesn't provide a comprehensive list of countries where their supply chains operate, 'Region-Specific Risk' on page 4 gives names of countries that are "associated with a higher risk of modern slavery (4)." Page 11 also names specific regions that the company is involved with for their supply chains - for instance, the document clams "Responsible Sourcing Program in Asia, Europe, the Middle East, and the Americas provide guidance to Suppliers on their Supply Chain Standards (11)." Moreover, the statement shows Amazon's partnerships with organizations to support their Suppliers in countries like Bangladesh and Pakistan (11).

I have changed the answer from Yes to No because the company does not explicitly disclose the countries where their supply chain operates. The statement mentions the following but does not provide a link:

We publish a map and list of Suppliers that produce Amazon-branded apparel, consumer electronics, food and beverage, and home goods products to provide customers and external stakeholders visibility into where we source. The map is updated annually in June and is subject to periodic updates. A file of the map data is available for download. (p. 5)
