【摘要】：The Trump administration heavily relies on economic sanctions to solve diplomatic problems. Those sanctions are far more protrusive than the ones enforced by his predecessors in terms of scale and scope of the intended target. The Trump administration has manufactured many new programs for sanctions and has attached much importance to imposing sanctions on entities that violate human rights. It also has increased its use of secondary sanctions, export controls and investment restrictions. Both sanction-related criminal enforcement and fines have hit new heights. The main reason for this strategy is that Trump and his economic team are keen on waging a"money war."Meanwhile, sanctions can appeal to Trump's requirements for quick, easy achievements, and can also contain and suppress opponents. The economic impact of these sanctions is obvious,while the political impact is still questionable. These sanctions have harmed the US alliance system and boosted the de-dollarization trend in the global economy, which makes it increasingly difficult for the United States to achieve its prospective goals in the future.
