[00:08.91]Trump described the talks as "very productive." [00:14.72]The two leaders met Sunday at Panmunjom, along the demarcation line separating North and South Korea. [00:26.54]By stepping across the line, Trump became the first United States president [00:33.97]to enter North Korea while in office since the division of Korea after World War II. [00:43.02]"Stepping across that line was a great honor," Trump said. [00:49.22]His private talks with Kim lasted about 50 minutes. [00:55.86]After the meeting, Trump announced that he and Kim had agreed [01:02.39]to form teams to restart talks between U.S. and North Korean officials. [01:12.00]The U.S. president said that both sides would meet over the next few weeks. [01:19.43]"Speed is not the object...we want a really comprehensive, good deal," he added. [01:28.60]Also present at the meeting was South Korean President Moon Jae-in. [01:36.52]The three leaders did not make a joint public statement [01:42.28]but appeared together before Trump's private meeting with Kim. [01:47.99]Moon praised the meeting as an important step. "We have taken one big step forward," he said. [01:58.72]The meeting at the demilitarized zone, known as the DMZ, is Trump's third with Kim Jong Un. [02:09.72]The first was in Singapore in June of 2018. [02:15.51]The second, held in Hanoi, Vietnam's capital, in February, ended without an agreement. [02:25.98]Trump said his negotiating team would continue to be led by the U.S. special envoy to North Korea, Steve Biegun. [02:38.73]He said North Korea "was putting someone in charge who we know and who we like." He did not give a name. [02:50.85]However, the two sides disagree over what should be done with North Korea's nuclear program. [03:01.13]In recent weeks, North Korea had expressed anger over continuing U.S. sanctions that have severely hurt its economy. [03:13.53]The U.S. has said that it will not ease the restrictions until North Korea fully gives up its nuclear weapons. [03:24.82]Mintaro Oba is a Korea expert and a former State Department official. [03:33.80]He said it is unclear whether either side is willing to soften its position. [03:42.14]"There is no sign that the two sides were prepared to address the underlying substantive problems, [03:52.19]like differences over sanctions relief, that have made diplomacy so difficult," he said. [04:00.62]U.S. officials have yet to say whether they are willing to accept some steps [04:09.31]toward denuclearization in exchange for some easing of the sanctions.
