The United States is quietly pursuing direct diplomacy with North Korea, a senior State Department official said on Tuesday, despite U.S. President Donald Trump's public assertion that such talks are a waste of time.
Using the so-called "New York channel," Joseph Yun, U.S. negotiator with North Korea, has been in contact with diplomats at Pyongyang's United Nations mission, the official said, at a time when an exchange of bellicose insults between Trump and North Korean leader Kim Jong Un has fueled fears of military conflict.
While U.S. Secretary of State Rex Tillerson on Oct. 17 said he would continue "diplomatic efforts ... until the first bomb drops," the official's comments were the clearest sign the United States was directly discussing issues beyond the release of American prisoners, despite Trump having dismissed direct talks as pointless.
There is no sign, however, that the behind-the-scenes communications have improved a relationship vexed by North Korea's nuclear and missile tests, the death of U.S. university student Otto Warmbier days after his release by Pyongyang in June and the detention of three other Americans.
Word of quiet engagement with Pyongyang comes despite Trump's comments, North Korea's weapons advances and suggestions by some U.S. and South Korean officials that Yun's interactions with North Koreans had been reined in.
"It has not been limited at all, both (in) frequency and substance," said the senior State Department official.
Among the points that Yun has made to his North Korean interlocutors is to "stop testing" nuclear bombs and missiles, the official said.
North Korea this year conducted its sixth and most powerful nuclear detonation and has test-fired a volley of missiles, including intercontinental ballistic missiles (ICBMs) that, if perfected, could in theory reach the United States mainland.
The possibility that Pyongyang may be closer to attaching a nuclear warhead to an ICBM has alarmed the Trump administration, which in April unveiled a policy of "maximum pressure and
engagement" that has so far failed to deter North Korea.
NATO chief Jens Stoltenberg has urged all United Nations members to fully and transparently implement sanctions against North Korea, which he said has emerged as a global threat.
Speaking at the United Nations on Sept. 19, Trump vowed to "totally destroy" North Korea if it threatened the United States or its allies, raising anxieties about the possibility of military conflict.
Twelve days later, after Tillerson said Washington was probing for a diplomatic opening, Trump said on Twitter that his chief diplomat was "wasting his time trying to negotiate with Little Rocket Man" - his mocking nickname for the North Korean leader.
Democratic U.S. senators introduced a bill on Tuesday they said would prevent Trump from launching a nuclear first strike on North Korea on his own, highlighting the issue days before the Republican's first presidential trip to Asia.
'Broader mandate' for diplomacy
At the start of Trump's presidency, Yun's instructions were limited to seeking the release of U.S. prisoners.
"It is (now) a broader mandate than that," said the official, declining, however, to address whether authority had been given to discuss North Korea's nuclear and missile program.
The New York channel is one of the few conduits the United States has for communicating with North Korea, which has itself made clear it has little interest in serious talks before it develops a nuclear-tipped missile capable of hitting the continental United States.
The last high-level contact between Yun and the North Koreans was when he traveled to North Korea in June to secure the release of Warmbier, who died shortly after he returned home in a coma, the official said.
The Trump administration has demanded North Korea release three other U.S. citizens: missionary Kim Dong Chul and academics Tony Kim and Kim Hak Song.
Warmbier's death was a factor in the chilling of U.S.-North Korean contacts around that time but the biggest impact came from Pyongyang's stepped-up testing, the official said.
The official said, however, that "the preferred endpoint is not a war but some kind of diplomatic settlement" and suggestions that Washington is setting up a binary choice for Pyongyang to capitulate diplomatically or military action were "misleading."
Diplomacy, the official said, "has a lot more room to go."
But Trump's threats against North Korea are believed to have complicated diplomatic efforts.
