Question: A unitary sovereign state in what part of the world was linked to illegal export of electronic waste?

<P0-S0> Electronic waste or e-waste in the United States refers to electronic products that have reached the end of their operable lives, and the United States is beginning to address its waste problems with regulations at a state and federal level. <P0-S1>  Used electronics are the quickest-growing source of waste and can have serious health impacts. <P0-S2>  The United States is the world leader in producing the most e-waste, followed closely by China; both countries domestically recycle and export e-waste. <P0-S3>  Only recently has the United States begun to make an effort to start regulating where e-waste goes and how it is disposed of. <SEP> <P1-S0> China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia and the world's most populous country, with a population of around /1e9 round 3 billion. <P1-S1>  Covering approximately 9.6 e6km2 , it is the world's second-largest state by land area and third- or fourth-largest by total area. <P1-S2>  Governed by the Communist Party of China, it exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing) and the Special Administrative Regions Hong Kong and Macau, also claiming sovereignty over Taiwan. <P1-S3>  China is a great power and a major regional power within Asia, and has been characterized as a potential superpower. <SEP> <P2-S0> Agbogbloshie is a nickname of a commercial district on the Korle Lagoon of the Odaw River, near the center of Accra, Ghana. <P2-S1>  Near the slum called "Old Fadama", the Agbogbloshie site became known as a destination for locally generated automobile and electronic scrap collected from across the City of Accra. <P2-S2>  It was alleged to be at the center of a legal and illegal exportation network for the environmental dumping of electronic waste (e-waste) from industrialized nations. <P2-S3>  Basel Action Network, a small NGO based in Seattle, has referred to Agbogbloshie as a "digital dumping ground", where they allege millions of tons of e-waste are processed each year. <P2-S4>  However, repeated international studies have failed to confirm the allegations, which have been labelled an "e-waste hoax" by international reuse advocate WR3A. <P2-S5>  The most exhaustive study of the trade in used electronics in Nigeria, funded by UNEP and Basel Convention, revealed that from 540 000 tons of informally processed waste electronics, 52% of the material was recovered. <SEP> <P3-S0> Executive Recycling is an Englewood, Colorado-based business specializing in electronic waste recycling. " <P3-S1> 60 Minutes" linked Executive Recycling to the illegal export of electronic waste from the Denver area to Guiyu, China. <P3-S2>  In the report, the company also was found to have illegally offered to help an undercover investigative team to ship more than 1,500 CRT (cathode ray tube) monitors and 1,200 CRT TVs to Hong Kong for recycling purposes. <P3-S3>  The story added that the federal government has issued a search warrant to investigate Executive Recycling's actions. <P3-S4>  Until November 2008, Executive Recycling was partnered with Colorado's Governor's Office of Economic Development to assist in recycling pickup events.
