Seoul: South Korean President Moon Jae-in credited U.S. President Donald Trump on Wednesday for helping to spark the first inter-Korean talks in more than two years, and warned that Pyongyang would face stronger sanctions if provocations continued.
The talks were held on Tuesday on the South Korean side of the demilitarised zone, which has divided the two Koreas since 1953, after a prolonged period of tension on the Korean peninsula over the North's missile and nuclear programmes.
North Korea ramped up its missile launches last year and also conducted its sixth and most powerful nuclear test, resulting in some of the strongest international sanctions yet.
The latest sanctions sought to drastically cut the North's access to refined petroleum imports and earnings from workers abroad.
Pyongyang called the steps an "act of war".
Seoul and Pyongyang agreed at Tuesday's talks, the first since December 2015, to resolve all problems between them through dialogue and also to revive military consultations so that accidental conflict could be averted.
"I think President Trump deserves big credit for bringing about the inter-Korean talks, I want to show my gratitude," Moon told reporters at his New Year's news conference.
"It could be a resulting work of the U.S.-led sanctions and pressure."
Trump and North Korean leader Kim Jong Un exchanged threats and insults over the past year, raising fears of a new war on the peninsula. South Korea and the United States are technically still at war with the North after the 1950-53 Korean conflict ended with a truce, not a peace treaty.
Washington had raised concerns that the overtures by North Korea could drive a wedge between it and Seoul, but Moon said his government did not differ with the United States over how to respond to the threats posed by Pyongyang.
"This initial round of talks is for the improvement of relations between North and South Korea. Our task going forward is to draw North Korea to talks aimed at the denuclearisation of the North," Moon said.
"(It's) our basic stance that will never be given up."
Moon said he was open to meeting North Korea's leader at any time to improve bilateral ties, and if the conditions were right and "certain achievements are guaranteed".
"The purpose of it shouldn’t be talks for the sake of talks," he said.
However, Pyongyang said it would not discuss its nuclear weapons with Seoul because they were only aimed at the United States, not its "brethren" in South Korea, nor Russia or China, showing that a diplomatic breakthrough remained far off.
North Korea's Rodong Sinmun newspaper said all problems would be resolved through efforts by the Korean people alone.
"If the North and South abandon external forces and cooperate together, we will be able to fully solve all problems to match our people's needs and our joint prosperity," it said.
Washington still welcomed Tuesday's talks as a first step towards solving the North Korean nuclear crisis.
The U.S. State Department said it would be interested in joining future talks, with the aim of denuclearising the North.
The United States, which still has 28,500 troops stationed in South Korea, initially responded coolly to the idea of inter-Korean meetings.
Trump later called them "a good thing" and said he would be willing to speak to Kim.
Lee Woo-young, a professor at the University of North Korean Studies in Seoul, said it was wise of Moon to praise Trump, his sanctions and pressure campaign.
"By doing that, he can help the U.S. build logic for moving toward negotiations and turning around the state of affairs in the future, so when they were ready to talk to the North, they can say the North came out of isolation because the sanctions were effective."
The United States and Canada are set to host a conference of about 20 foreign ministers on January 16 in Vancouver to discuss North Korea, without the participation of China, Pyongyang's sole major ally and biggest trade partner.
China would not attend the meeting and is resolutely opposed to it, said foreign ministry spokesman Lu Kang.
"It will only create divisions within the international community and harm joint efforts to appropriately resolve the Korean peninsula nuclear issue," he told a regular briefing on Wednesday.
Pyongyang also said it would send a large delegation to next month's Winter Olympics in South Korea.
Washington agreed with Seoul last week to postpone until after the Olympics joint military exercises that Pyongyang denounces as rehearsals for invasion.
But it also said the apparent North-South thaw had not altered the U.S. intelligence assessment of the North’s weapons programmes.
The United States has also warned that all options, including military, are on the table in dealing with the North.
"We cannot say talks are the sole answer," Moon said.
"If North Korea engages in provocations again or does not show sincerity in resolving this issue, the international community will continue applying strong pressure and sanctions."
Seoul said on Tuesday it was prepared to offer financial assistance and lift some unilateral sanctions temporarily so North Koreans could attend the Olympics.
North Korea said its delegation would include athletes and officials, among others.
However, Moon said on Wednesday South Korea had no plans for now to ease unilateral sanctions against North Korea, or revive economic exchanges that could run foul of United Nations sanctions.
