Pence is visiting South Korea beginning Sunday, part of an Asia-Pacific trip that comes amid indications that North Korea is potentially preparing its sixth nuclear test in a decade or a significant missile launch. It's North Korea's most important holiday and a large-scale military parade is expected.
Pence will "reaffirm" the United States' commitment to the "ironclad" U.S. He said, North Korea may already have the capability to shoot missiles loaded with sarin as warhead against Japan, CTV news reported Thursday.
"We're going to continue to consult with the Republic of Korea on North Korea's efforts to advance its ballistic missile and its nuclear program", the official said.
That came as South Korea's Foreign Ministry warned Pyongyang against any provocative acts of its own, such as a missile test, which some believe may be carried out against the backdrop of tomorrow's celebrations.
"Remember, President Donald Trump said, "...the problem will be taken care of".
"Trump is always making provocations with his aggressive words", Han said.More news: Tottenham close gap on Chelsea
Pence said Sunday at a fellowship dinner at U.S. Army Garrison Yongsan in Seoul that the willingness of military members "to stand firm without fear inspires the nation and inspires the world".
In recent months, a series of top USA officials have visited South Korea amid concerns that security cooperation between the allies could slacken in the wake of the March 10 ouster of former President Park Geun-hye over a corruption scandal.
Pence is tasked with explaining the policy in meetings with leaders in South Korea and Japan at the start of a 10-day tour that will include stops in Indonesia and Australia.
In Japan, Pence will kick off economic talks first announced by Trump and Japanese President Shinzo Abe after their February summit.
USA officials say the Trump administration's emphasis will be on increasing pressure on Pyongyang with the help of China.
According to the Washington Post, Trump told Turnbull on the call the refugee agreement was the "worst deal ever".
