President Donald Trump’s tough stance with China has won over many supporters — from Democrats to farmers. But not everyone is a fan of his approach of imposing tariffs.

“Billions of Dollars are pouring into the coffers of the U.S.A. because of the Tariffs being charged to China, and there is a long way to go,” Trump tweeted Thursday morning. He declared a trade war with China by slapping 25% tariffs on $50 billion worth of imported goods from China in June and threatened to raise the current 10% tariffs on $200 billion worth of goods to 25% next year, although both sides are reportedly exploring a deal to delay that would prevent an escalating trade war.

To investors, business people and economists, tariffs aren’t as sweet of a deal as the president claims. When businesses voice concerns over tariffs, the administration has a centerpiece in its argument: slapping tariffs on China is a negotiation tactic and the only effective tool to push China to change.

“What other weapons do we have?” U.S. Commerce Secretary Wilbur Ross said at the Yahoo Finance All Markets Summit. Art Laffer, an advisor to Trump during his 2016 presidential campaign, said Trump told him that he has “very little leverage except by threatening tariffs.”

But outside the administration, people see other ways to address China’s unfair trade practice. Neil Bradley, chief policy officer at the U.S. Chamber of Commerce, while recognizing the administration’s efforts to confront China, called the idea of using tariffs as the only solution “misguided”.

“There’s a lot of other places to play here to confront this problem without resorting to broad-based tariffs. It would harm consumers and it would harm the American economy,” said Bradley at the Yahoo Finance All Markets Summit.

Bradley sees indicting bad actors and working with allies in a collective approach is a better way to deal with China. Earlier this month, the Department of Justice charged a Chinese state-owned company with stealing trade secrets from an American technology company.

“That’s a blunderbuss approach to a very real problem versus a tactical scalpel-like approach, where you identify the bad actors and punish them,” Bradley said of imposing tariffs.

The administration prefers bilateral trade talks

Bradley also believes “the best thing” the U.S. can do is to team up with other players in the world’s trade system, including Japan, Canada, Europe, and confront China collectively.

But the administration doesn’t seem to be a fan of the multilateral approach. While in trade disputes with China, Trump was also in tough negotiations with the EU and other major trading partners.
