Zambia's new president is replacing the country's top anti-corruption official.

The announcement from President Michael Sata's office Saturday is the latest in a series of moves ridding the government of anyone perceived to have close ties to his predecessor.

Mr. Sata named Rosewin Wandi to take over as director general of the Anti-Corruption Commission (ACC). Wandi would replace Godfrey Kayukwa, who was accused of mishandling previous corruption investigations.

The 74-year-old Sata scored a decisive victory over former leader Rupiah Banda in the country's elections late last month. After taking office, Mr. Sata promised to help the nation's poor and to fight corruption.

Mr. Sata had repeatedly accused Mr. Banda of tolerating corruption and not doing enough to ensure that more Zambians share in the wealth of the country's copper reserves.

President Sata also assured foreign investors that they are welcome in his country, Africa's biggest copper producer, but said they must improve conditions for their Zambian employees.

In the past, Mr. Sata has criticized China, which has invested heavily in Zambia's mining industry.
