"President Trump said that the tariffs would not go into effect until Nov 1. He will be meeting with Party Chair Xi in Korea. I believe that meeting will still be on."
Trump and Xi had planned to meet during the summit of the Asia-Pacific Economic Cooperation forum hosted by South Korea in late October.

"The 100% tariff does not have to happen," Bessent said. "The relationship, despite this announcement last week, is good. Lines of communication have reopened, so we'll see where it goes."
