From the Overview: "U.S. relations with Zimbabwe, a mineral-rich southern African country, remain strained. Tensions in bilateral relations emerged in the late 1990s, when increasing indications of human rights violations, undemocratic governance, and economic decline, accompanied by radical government economic policies and land seizures, spurred concern among Members of Congress and other U.S. policymakers. Bilateral relations since that time have been--and remain--dominated by U.S. policy, diplomatic, and targeted assistance efforts intended to prevent and counter such outcomes, mitigate their effects, and push for policy and governance reforms in Zimbabwe, as well as alleviate socioeconomic hardships among the country's people. Legislation enacted by Congress is a key component of these policy efforts."
