The European Commission criticized the temporary extension in a statement Tuesday. The group said the EU has been willing to discuss the issue and "will not negotiate under threat."
欧盟委员会周二在一份声明中批评了这次临时延期。该组织表示，欧盟愿意讨论这个问题，“不会在威胁下进行谈判。”
The commission said, "The U.S. decision prolongs market uncertainty, which is already affecting business decisions." It added that the tariffs, which are meant to protect U.S. industry, cannot be justified by national security concerns.
该委员会表示：“美国的决定延长了市场不确定性，这已经影响到了商业决策。”声明还补充说，关税旨在保护美国工业，不能用国家安全考虑来证明其合理性。

The Trump administration has said that some countries sell their steel and aluminum at unfairly low prices. And President Donald Trump has said this competition hurts U.S. industries that are important to national security.
川普政府曾称一些国家以不合理低价出售其钢铁和铝产品。川普总统曾表示，这种竞争会伤害对国家安全至关重要的美国工业。
The U.S. has placed a 25 percent tax on many steel imports and a 10 percent tax on aluminum as a result.
因此美国对大部分进口钢铁征收25%的关税，对铝产品征收10%的关税。
