China to work with Ghana on illegal mining

Illegal mining in Ghana, particularly of gold, has become a major issue and also raised concerns about water pollution and environmental damage.
Last year hundreds of people, most of them from China, were detained as the government began enforcing a law barring foreign nationals from engaging in small-scale mining operations.
Ghana is Africa's second-largest gold producer after South Africa and Chinese nationals in particular have flocked to the country in search of the yellow metal and their fortune.
Some Chinese, many of them from Shanglin county in Guangxi province which also has a tradition of gold mining, have agreed to leave voluntarily although others have been repatriated
