SEOUL, South Korea -- North and South Korea exchanged messages Tuesday in communication channels that have been dormant for more than a year and agreed to improve ties -- positive steps but ones that still leave any resumption of stalled negotiations to rid the North of its nuclear weapons a long way off.
Liaison officials from the Koreas had several phone conversations including one on a military hotline and agreed to resume speaking regularly, Seoul officials said. The rivals use the channels to lay out their positions on issues and even propose broader dialogue, and the links also are critical to preventing any accidental clashes along their disputed sea boundary.
While the renewed communication could help ease tensions across the world's most heavily fortified border, it's only a small first step. Pyongyang is unlikely to revive vigorous cooperation programs with Seoul or get back to the nuclear talks led by the United States anytime soon. Some experts say North Korea is instead aiming to improve ties with South Korea in the hopes of persuading the U.S. to make concessions when nuclear diplomacy with Washington eventually does resume.
Those efforts have been stalled for more than two years by wrangling over punishing U.S.-led sanctions on the North. During the diplomatic impasse, North Korean leader Kim Jong Un has threatened to enlarge his nuclear arsenal if the U.S. doesn't abandon its hostile policy, an apparent reference to the sanctions.
On Tuesday, the two Koreas announced their leaders -- Kim and South Korean President Moon Jae-in -- have traded personal letters several times since April and decided in those exchanges to resume communication in the channels.
Moon's office said the two leaders agreed to "restore mutual confidence and develop their relationships again as soon as possible." The North's state media, for its part, said Kim and Moon agreed to "make a big stride in recovering the mutual trust and promoting reconciliation by restoring the cutoff inter-Korean communication liaison lines."
Tuesday's resumption of communication takes place on the 68th anniversary of the signing of the armistice that ended the 1950-53 Korean War, which pitted South Korea and U.S.-led U.N. forces against North Korea and China. That armistice has yet to be replaced with a peace treaty, leaving the Korean Peninsula in a technical state of war, with about 28,500 U.S. troops still stationed in South Korea.
North Korea occasionally cuts off communication in the channels -- by not replying to South Korean phone calls or faxes -- in times of tensions with Seoul and Washington.
The most recent cutoff happened in June of last year after North Korea accused the South of failing to stop activists from floating anti-Pyongyang leaflets across their border. An angry North Korea later blew up an empty South Korean-built liaison office just north of the countries' border.
The U.S. sanctions, together with storms last summer and border shutdowns during the coronavirus pandemic, are battering the isolated North's economy, creating what Kim called its "worst-ever" crisis. Still, outside monitoring groups haven't seen signs of mass starvation or social chaos in the country of 26 million people.
Nam Sung-wook, a professor at Korea University, said the resumed communication likely won't lead to a dramatic improvement in ties in the near term -- but could pave the way for something down the road.
"North Korea knows it has to sit down for talks with the Biden administration one day. It thinks South Korea still has an effective value ... to make [President Joe] Biden move" in a direction that it favors, said Nam. "North Korea can also build up an [international image] that it's willing to continue dialogue" with the outside world.
Senior South Korean presidential official Park Soo Hyun said later Tuesday that Seoul believes improved ties between the Koreas would help restart the stalled nuclear diplomacy.
Moon, who espouses greater reconciliation with North Korea, earlier shuttled between Pyongyang and Washington to facilitate a 2018 summit between Kim and then-U.S. President Donald Trump -- the first such meeting between the countries' leaders. But North Korea abruptly gave Moon the cold shoulder after a second proposed Kim-Trump summit fell apart in early 2019 after Trump rebuffed Kim's push to win extensive sanctions relief in return for dismantling his main nuclear complex.
Since taking office in January, Biden's administration has called on North Korea to return to a negotiating table. But last month senior North Korean officials, including Kim's powerful sister, dismissed prospects for an early resumption of the talks.
Some experts think North Korea may be compelled to reach out to the U.S. or South Korea if its economic difficulties worsen. By taking steps to improve relations with Seoul now, the North may be preparing for that moment.
