GYEONGJU, South Korea - U.S. President Donald Trump said on Wednesday a trade deal had been struck with South Korea, in remarks that sent the won up against the dollar, as a compact promises to dispel uncertainty for the trade-reliant economy.

"We did, we did. We did reach a deal," Trump said in response to a query on whether a deal was struck, ahead of a dinner hosted by South Korean President Lee Jae Myung.
