Jan 23 (Reuters) - Wall Street was poised to open little changed on Tuesday as U.S. President Donald Trump's move to impose steep import tariffs raised concerns that such measures could prompt retaliation and weigh on a revival in international trade.
South Korea and China protested against the duties on washing machines and solar panels, with Seoul saying it would respond to the spread of protectionist measures.
"We don't know if this is the beginning of something larger or if it's something that will escalate into a trade war," said Art Hogan, chief market strategist at B. Riley FBR in Boston.
Hogan also said it sparked fears about U.S. walking away from NAFTA.
NAFTA's future hangs in the balance this week as negotiators from the United States, Canada and Mexico try to settle major differences over revamping a pact that Trump has threatened to abandon.
