Citing unidentified USA officials, the Washington Post reported last week that Russian Federation invited Choe to "feel out Pyongyang as to a possible resumption of dialogue between the United States and North Korea".
Choe herself served as an aide and interpreter at the six-party talks on North Korean denuclearization, which involved Pyongyang, Seoul, Washington, Beijing, Tokyo and Moscow, before that diplomatic endeavor ended in 2008 when North Korea walked out.
Choe Son Hui, director-general of the North American department at North Korea's Ministry of Foreign Affairs, is slated to meet with Oleg Burmistrov, the Russian ambassador at large in charge of the North Korean nuclear issue. Moscow said it is willing to work with Pyongyang towards a peaceful resolution of the nuclear tensions after a meeting between Russian and North Korean officials in Moscow on September 29, 2017.
Referring to the talks, State Department spokeswoman Heather Nauert told a regular press briefing on Thursday: "I can't see that as a bad thing".
"Diplomacy is our preferred approach".
Other senior administration officials are more suspicious.
General Lori Robinson, the head of the US Northern Command and the North American Aerospace Defense Command (or NORAD), said today that this fact was something she is "aware of".
Russian Federation and China have previously said they both support a "suspension-for-suspension" approach to reign in North Korea's missile and nuclear weapons program.
But in the Korean Peninsula, Russia's increasing involvement is welcomed by one of the US key ally in the region, too.
"During the consultations, opinions will be exchanged on the situation developing on the Korean Peninsula and in northeastern Asia", Zakharova said, without providing further details.
