However, skeptics in the West and South Korea said that the Sunshine Policy of a decade ago, which promoted warmer relations between the two Koreas, failed to halt Pyongyang's nuclear progress.
"Absolutely, I would do that", Mr Trump said.
"These are constructive comments by the president", said Nicholas Burns, a former undersecretary of state under President George W. Bush who's now a professor at the Harvard Kennedy School.
The latest round of sanctions passed in December bans the supply of almost 75 per cent of refined oil products to North Korea, puts a cap on crude deliveries and orders all North Korean nationals working overseas to be sent back by the end of 2019.
There is no doubt the South needs close consultation and cooperation with the U.S.to make the inter-Korean talks a success in the face of the North Korean nuclear standoff.
Haley said North Korea should be clear that the United States will not reduce pressure on Kim. "Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!"
Despite Pyongyang's willingness to talk to its southern neighbor, experts say the DPRK will not be letting go of its nuclear weapons program anytime soon.
Catalan separatists seek to reelect their leader
The move backfired when independence parties across the political spectrum won a narrow majority in the assembly. Junqueras has asked for release from jail to attend the first meeting of the new Catalan parliament.
Dr. Go Myong-Hyun, Research Fellow at The ASAN Institute for Policy Studies said Kim's willingness for dialogue is a temporary plan built out of desperation: "North Korea is engaging in a tactical move with South Korea for two main reasons: to avoid a preemptive attack from the U.S., and to mitigate crippling sanctions imposed on the country by the USA".
Baik added he understands that "the North Korean side is also scheduled to have talks with the IOC (International Olympic Committee) next week". The commentary warned that "depending on foreign powers" risked complicating talks.
Still, both the US and South Korea want no disruptions during the Olympics in Pyeongchang, about 50 miles (80 kilometers) from the heavily fortified border between the two Koreas.
South Korean opposition parties have struck a cautious tone over the latest developments, warning against making concessions to the North to secure its Olympic participation. "There's nothing where they can drive a wedge at all".
"The priority is on North Korea's participation in the PyeongChang Olympic Winter Games", a ranking South Korean official was quoted as saying by Yonhap News Agency.
US officials cautioned that the North's peace overture may be aimed at driving a wedge between Seoul and Washington and will weaken the global sanctions against the reclusive country. Chang told reporters Saturday at Beijing Capital International Airport that a pair of North Korean figure skaters were likely to compete, Japan's Kyodo News reported. If North Korea responds by suspending military tests, then the "dual suspension" will be in effect, which Russian Federation and China-and Lyndon and Helga LaRouche-say is required to move to negotiations for a durable settlement. He has indicated he is open to many different options, including military strikes on North Korea's launch capabilities. "Talks for the sake of talks are meaningless".
