The White House has said the first meeting ever between sitting U.S. and North Korean leaders could take place in the coming weeks.
Washington: President Donald Trump on Friday said the date and location have been set for a meeting with North Korean leader Kim Jong Un, building suspense for the unprecedented talks, as South Korea said it would oppose a withdrawal of U.S. troops from the area.
Chung told reporters afterward that it was "unacceptable that the issue of the U.S. forces Korea keeps being raised."
The White House said in a statement late on Friday that Bolton and Chung said there are no plans to change the U.S.-South Korea bilateral defence posture.
The U.S. government is looking into reports that three Americans arrested in recent years in North Korea had recently been relocated from a labour camp to a hotel near Pyongyang, as expectations grow that they will be released before the summit.
"We're having very substantive talks with North Korea and a lot of things have already happened with respect to the (U.S.) hostages. I think you're going to see very good things," Trump said.
