By Joyce Lee, Hyunjoo Jin and Trevor Hunnicutt SEOUL/WASHINGTON (Reuters) -U.S. President Donald Trump and South Korea's new president Lee Jae-myung agreed to work toward a swift tariff deal in their first phone call since Lee was elected this week,

Lee took office on Wednesday just hours after riding a wave of anger over a brief martial law imposed by Yoon Suk Yeol to win the snap election. The attempt at military rule led to Yoon's ouster and sent shockwaves through Asia's fourth-largest economy.

South Korea's new President Lee Jae-myung said he and President Donald Trump agreed to quickly work toward a deal on tariffs in their first phone call since Lee's election victory.
