N. Korea, U.S. Set for Icy Encounter at Olympics as North Delegation Arrives

North Korea’s ceremonial leader and U.S. Vice President Mike Pence may have their first face-to-face encounter on Friday at the opening ceremony of the Pyeongchang Winter Olympics, as Washington prepares more sanctions against the North.

Any contact between the two will likely be tense after V.P. Pence said South Korean President Moon Jae-in gave his backing to additional measures the United States is planning to try to curb North Korea’s missile and nuclear programs.

The vice president said Moon acknowledged the effectiveness of sanctions in bringing North Korea to inter-Korean talks.

“President Moon reaffirmed to me his strong support of our extreme pressure campaign to continue to bring additional sanctions on North Korea,” V.P. Pence told reporters.

He spoke after paying tribute at a memorial for 46 South Korean sailors killed in the sinking of a warship in 2010 that Seoul blamed on a North Korean torpedo attack.

V.P. Pence arrived in South Korea on Thursday and spoke with Moon, both reiterating their commitment and cooperation to defuse tensions as North Korea pushes ahead with its weapons programs in defiance of U.N. Security Council resolutions.

Kim Yong Nam, North Korea’s nominal head of state, landed in South Korea on Friday along with leader Kim Jong Un’s younger sister, Kim Yo Jong, aboard her brother’s private jet.

The white aircraft had Democratic People’s Republic of Korea, North Korea’s official name, inscribed in black in Korean on its side, followed by the North Korean flag.

Kim Yo Jong and her delegation were greeted by government officials, including Unification Minister Cho Myong-gyon, before boarding a bullet train to Pyeongchang. A special train had been prepared just for the visitors, a Blue House pool report said.

Kim Yo Jong is the first member of North Korea’s ruling family to visit the South, while Kim Yong Nam is the most senior North Korean official to make a cross-border trip.

The pair will have lunch with South Korean President Moon Jae-in on Saturday, Moon’s office said.

Vice President Pence has kept open the possibility for some contact with the North Koreans in South Korea, while reiterating Washington’s insistence that denuclearization by North Korea is a necessary condition for peace.

V.P. Pence, Kim Yo Jong and other world leaders will attend the Olympics’ opening ceremony in Pyeongchang, just 50 miles from the heavily fortified border between North and South Korea, later on Friday.

Hundreds of anti-North Korea protesters scuffled with riot police hours not far from the main stadium before the opening ceremony was due to begin.

“Moon regime is leading Korea to destruction” read one of the banners the protesters were holding up.

Moon will hold a welcoming reception for his top guests before the Olympics open, a presidential official said, where Mike Pence and Kim Yong Nam could sit at the same table with Moon.

South Korea hopes the Olympics can demonstrate its efforts to defuse tensions and foster inter-Korean rapprochement, and athletes from the two Koreas will march together under one peninsula flag for the first time in more than a decade.

However, the inter-Korean Olympics detente has raised concerns in Washington and Tokyo that Seoul may undermine the U.S.-led campaign of global pressure to get Pyongyang to abandon its nuclear and missile programs.

Moon held a summit with Japanese Prime Minister Shinzo Abe on Friday, during which they discussed the North Korea standoff and some sensitive issues.

In opening remarks provided by the Blue House, Abe said he wished to reaffirm close cooperation between Japan, South Korea and the United States in regard to North Korea.

Abe said before leaving for the Olympics that he wanted to convey to the world that that cooperation “will not waver.”
