Migration of Chinese people in Ghana dates back to the 1940s. Originally, most came from Hong Kong; migration from mainland China began only in the 1980s. The China Africa Research Initiative at Johns Hopkins University School of Advanced International studies https://www.sais.org cites the total number of Chinese workers in Africa in 2018 as 201,057 as per the National Bureau of Statistics of China which is corroborated by other sources such as The Almanac Of China's Foreign Economic Relations and Trade, and The China Annual Bulletin Of Statistics Of Contracted Projects. This figure indicates a steady decline from the previous years 2015-2017 but however, ostensibly does not account for informal migrants such as traders and shopkeepers.
