The Vice President of the United States Mike Pence, now on a 10-day long tour of Asia, arrived at the second stop of his tour as he landed in Tokyo on Thursday.
The focus of his trip is expected to shift in Japan to trade.
But in an interview with me on Wednesday afternoon, he adopted a harder line: The Trump administration, he said, demands that North Korea abandon its nuclear and ballistic missile programs without any promise of direct negotiations with the United States.
"We have to be honest where our trade relationship is falling short", he said at a meeting with business leaders in Seoul on Tuesday. This strategy is part and parcel of Trump's "America First" doctrine.
But time and again, the regime had answered the overtures with "willful deception, with broken promises, and nuclear and missile tests", he said.
Last week China warned that the two nations "need to stop provoking one another " and that there would be "no winners" if war between the USA and North Korea broke out.

President Trump has made it clear that the patience of the United States and our allies in this region has run out, and we want to see change.
Deputy Prime Minister Taro Aso stressed the importance of multilateral economic frameworks, saying that Japan and the United States should take the lead in establishing rules of regional trade in Asia and the Pacific. Details on the vice president's meetings with officials in the four countries is scant, but a statement released by the White House shows that business issues will figure prominently, and senior officials from the four countries have indicated that trade is likely to come up.
