Republican presidential candidate Nikki Haley blasted Donald Trump over his plans to impose sweeping tariffs on foreign imports.

Haley, who is running far behind Trump in the Republican primary, claimed that Trump's plans to impose a 10% tariff on imports would raise costs for Americans.

Her comments echoed President Biden, who has made similar attacks on Trump's "America First" protectionist agenda.

Haley rips Trump tariffs

Trump has championed using tariffs to bring jobs back to the country, but his plans have long been criticized by free trade advocates, including many free-market Republicans who say tariffs are detrimental to the economy.

If re-elected, Trump has promised to enact even more significant tariffs than he did in his first term. In addition to a universal 10% tariff on imports, Trump reportedly wants to slap a whopping 60% tariff on goods from China.

Trump doubled down recently on his threats to force automakers to bring jobs back from China and Mexico.

″[I] would require China, and other countries, through TARIFFS, or otherwise, to build plants here, with our workers,” Trump wrote on Truth Social.

Haley blasted Trump's proposals in an interview with the financial news channel CNBC, which tends to parrot Wall Street talking points.

She made the comments while visiting New York City to meet with the Wall Street donors fueling her campaign.

"This is a man who now wants to go and put 10 percent tariffs across the board, raising taxes on every single American. Think about that for a second,” Haley told CNBC's Squawk Box. 

"Globalist" Haley echoes Biden

Biden has similarly attacked Trump's plans to expand tariffs, claiming they would fuel inflation - despite the fact that Biden has kept Trump's China tariffs.

While Haley has parroted Trump's anti-China rhetoric, the Trump campaign noted that she encouraged Chinese investment in South Carolina when she was governor of the state.

"In 2014, Haley wanted the U.S. Commerce Department to lower a tariff on tires made in China by Giti Tire, which was in the middle of building a $560 million plant in South Carolina," Trump spokesman Steve Cheung said.

Haley is Trump's last remaining primary challenger after he dominated early contests in Iowa and New Hampshire last month.

Trump is certain to continue attacking Haley as an out-of-touch "globalist" as she faces a make-or-break moment in her home state of South Carolina on February 24.
