TOKYO — Vice President Mike Pence said the U.S. is preparing to announce the "toughest and most aggressive" economic sanctions against North Korea in the coming days, boosting pressure on the bellicose government during the Winter Olympics.
Pence, who is set to lead the U.S. delegation at the opening ceremonies Friday, made the announcement in Japan on Wednesday, following meetings with Prime Minister Shinzo Abe.
"The United States of America will soon unveil the toughest and most aggressive round of economic sanctions on North Korea ever — and we will continue to isolate North Korea until it abandons its nuclear and ballistic missile programs once and for all," Pence said.
U.S. officials declined to provide details of the expected sanctions beyond Pence's comments, citing concerns that any additional information could be used by those trying to skirt the new measures. They are expected to be implemented before the conclusion of the games.
North Korea is already facing unprecedented sanctions after three U.N. Security Council restrictions in the past year that have slashed the pariah nation's export revenue and capped fuel imports. Unilaterally, the U.S. has also targeted North Korean shipping companies and Chinese trading networks. A potential escalation of sanctions could be U.S. blacklisting of Chinese banks accused of providing North Korea access to the international financial system and facilitating sanctions evasion.
On a six-day trip to Japan and South Korea, Pence is seeking to reassure and refocus American allies on the growing nuclear threat from North Korea.
In meetings with government leaders, military officials and U.S. service members, Pence said he wants to make sure the Pyeongchang Winter Olympics don't distract from North Korea's human rights abuses and nuclear program. He met with Abe at his official residence to discuss increasing pressure on the North.
"The United States is with you in this challenge," Pence told Abe as they began their talks. "And we will continue to stand shoulder to shoulder with the people of Japan, the people of South Korea, and our allies and partners across the region until we achieve the global objective of denuclearization of the Korean Peninsula."
Pence watched Japanese troops demonstrate the simulated deployment of Japan's surface-to-air missile defense system, which would attempt to intercept a North Korean missile. He also participated in a briefing at Japan's Ministry of Defense on the threat.
"The people of Japan can be assured: The full range of the Armed Forces of the United States will continue to be dedicated to the protection of Japan," Pence said, promising again that "all options are on the table" to address the North Korean threat.
Pence will travel on to South Korea on Thursday for meetings with President Moon Jae-in, where he will promote the Trump administration's campaign of "maximum pressure" against the North, as the South pursues a diplomatic opening around the Winter Olympics.
Pence's tough message is jarringly different to the tone struck by Moon, a liberal leader who has long advocated greater engagement with Pyongyang. While Seoul loyally supports the Trump administration's pressure campaign, and agrees improvement in inter-Korean relations requires progress on the nuclear issue, the U.S. and South Korea face a stiff challenge in reconciling their contrasting tactics of confrontation and conciliation. North Korean leader Kim Jong Un is widely viewed as trying to weaken the alliance and the impact of sanctions.
As North Korea's march toward obtaining nuclear-tipped missiles capable of reaching the U.S. has exceeded the American government's estimates, the Trump administration has worked to rally the international community to embrace tougher economic sanctions and isolation of the North.
