APEC’s members account for about 38 percent of the world’s population and 61 percent of the world’s GDP, according to APEC’s official publication.APEC and the World Trade Organization (WTO) share the same goal of free and open trade across borders. Unlike the WTO, APEC does not have strict rules that members must follow. Its members reach agreements together and take action voluntarily (自愿地).
