President Donald Trump on Saturday signed an order to impose stiff tariffs on imports from Mexico, Canada and China, drawing swift retaliation from the country’s North American neighbors as a trade war erupted among the longtime allies.

Arizona business leaders reacted to the president’s decision with concern.

"Strong trade policies should help businesses grow and keep costs down for American consumers—not make things more expensive. Tariffs aren’t a tax on foreign countries; they’re a tax on American businesses, consumers and families,” said Danny Seiden president and CEO of the Arizona Chamber of Commerce and Industry.

“This move threatens to disrupt operations, slow economic growth and raise prices at a time when affordability is already a major concern for families. We’ll be working closely with (Gov. Katie Hobbs’) team and our congressional delegation to ensure Arizona remains competitive and that businesses aren’t caught in the crossfire.”

The Republican president posted on social media that the tariffs were necessary “to protect Americans,” pressing the three nations to do more to curb the manufacture and export of illicit fentanyl and for Canada and Mexico to reduce illegal immigration into the U.S.

Hobbs said the tariffs are a tax, threatening to hike grocery, gas and housing prices.

“I hope the president will reconsider this hasty action that could have a devastating impact on our state’s economy,” the Democratic governor said.

Sandra Watson, Arizona Commerce Authority president and CEO, said "Arizona's surging economy is fueled, in part, by our growing exports and strong international partnerships, especially with our top trade partner, Mexico.

 “Our policies should make it easier for Arizona businesses to expand into new markets and grow their operations, not put up new barriers."

In a statement, Greater Phoenix Chamber officials said the tariff repercussions on businesses and consumers are “significant.

“We call upon the Administration to prioritize constructive negotiations and seek solutions that benefit all parties involved. It is imperative that we avoid measures that could hinder our economic progress and instead focus on building a future of shared success and stability.”
