俺也试一下：

Mnuchin在峰会上重申了床铺总统对美国公司和工人的承诺，反驳了相反的观点，并有效地使会后发表的联合声明中未提到有关贸易保护主义的禁令。

“Citing President Donald Trump's commitment to American companies and workers, Mnuchin pushed back on and effectively omitted a ban on protectionism from the joint statement released at the end of the summit.”

Push back on - 此处意争论，argue，反对，oppose.
