"We see sustainability as a key customer requirement, and embed it into our procurement strategies and processes to increase transparency across our supply chain. We work closely with customers on supplier management. For example, we invite customers to visit supplier facilities, conduct joint supplier audits with customers, and carry out employee surveys and supplier capacity building projects. All these efforts help improve our own sustainability. In 2018, Huawei and seven customers ran onsite audits on 21 suppliers, and we shared the audit results with the customers."
