In recent years, the United States applied economic sanctions to solve international issues frequently.The US economic sanctions have relatively suficient basis in their domestic laws, forming a systematic legalsystem. At present, there are a large number of US legislations on economic sanctions At the federal level,the relevant legislations can be basically divided into three types: authorization legislations, direct sanctionslegislations, and other legislations that include sanctions. The above-mentioned legislations have shown somefragmentation in practice. The main reason lies in the power game between the executive branch and theCongress in terms of foreign policy power. As to implementation, economic sanctions are mainly implementedby the Ministry of Finance, the State Council and the Ministry of Commerce, and implementation measuresare gradually based on financial sanctions. There is no remedy for sanctions in US legislations. In addition to negotiating with the United States to seek to lift sanctions, the targets of sanctions have sometimes broughtlawsuits in various courts and international judicial institutions. Although the political nature of sanctionsdetermines that it is difficult to resolve related issues entirely through judicial channels, the lawsuits haveexerted pressure on the United States in certain circumstances forcing it to modify certain measures.
