United States President Donald Trump has signed into law the amended Zimbabwe Democracy and Economic Recovery Act (ZDERA).
The bill was passed by the US Congress last month and sets tough conditions for Zimbabwe to re-engage with the US.
In a statement, the White House said the signing of the law means that sanctions on Zimbabwe will continue for now.
ZDERA was first imposed on Zimbabwe in 2001after the southern Afrivcan country redistributed land to the landless majority who were marginilised during the colonial era.
The land reform programme irritated the British who influenced the USA and its other allies to punish Zimbabwe through economic sanctions.
