Dongguan (simplified Chinese: 东莞; pinyin: Dōngguǎn) is a prefecture-level city in central Guangdong province, People's Republic of China. An important industrial city located in the Pearl River Delta, Dongguan borders the provincial capital of Guangzhou to the north, Huizhou to the northeast, Shenzhen to the south, and Foshan to the west. It is also home to the world's largest shopping mall, South China Mall. City administration is considered especially progressive in seeking foreign direct investment (see below). The three neighboring muncipalities of Guangzhou, Dongguan, and Shenzhen are home to over 25 million residents, accounting for a large proportion of the Pearl River Delta's population.
