“The changes made are meaningful but modest,” said Wendy Cutler, who negotiated the original U.S.-Korea deal, known as Korus, under Presidents Bush and Obama. “The president set very high expectations that this was a terrible agreement and he was going to totally change it and reduce the bilateral trade deficit, but this seems to be pretty traditional agreement,” she added. Ms. Cutler also noted that “Korea came in with its own demands, and the U.S. was responsive—the U.S. gave as well as got.”
