Kim Jong-un defied the worldwide community in 2016 with North Korea's fourth and fifth nuclear tests in a decade then began 2017 by claiming his nation was in the "last stage" of preparations to test-fire an inter-continental ballistic missile.
It is not clear whether this was a deliberate deception, a change of plan or simple miscommunication, the BBC's Korea correspondent Stephen Evans says.
"American officials did make some positive and constructive remarks. such as using whatever peaceful means possible to resolve the (Korean) Peninsula nuclear issue".
North Korea's official Korean Central News Agency called the carrier's deployment "nothing but a reckless action of aggression to aggravate the tensions in the region".
Koh Yu-hwan, a North Korea expert at Seoul's Dongguk University, said that the way US officials describe "maximum pressure and engagement" suggests that the Trump administration wants to ease Chinese fears about a collapse in North Korea, something that prevented Beijing from aggressively pressuring the North in the past. As a result, USA planners are not taking any chances when it comes to stepping-up missile defense technology and preparedness. TRADE WITH JAPAN Japan has less room to compromise with the United States under a bilateral trade deal than under a multilateral agreement like the Trans-Pacific Partnership, its deputy prime minister says, taking a swipe at US attempts to directly pressure Tokyo into opening up heavily protected markets like agriculture.
Japan is drawing up emergency responses in case of a North Korea missile strike. In his brief comments at the heavily guarded border, the US vice president warned North Korea that "the era of strategic patience is over". It could be a deliberate ploy, a subtle warning to North Korea, but beyond that there seems to be no strong reason for a strike.
Pence spoke in Tokyo to the U.S. Chamber of Commerce in Japan Wedneaday. It also stated that Pyongyang's ballistic missile launches are "illegal" and that the country has been developing nuclear weapons.
On Sunday, North Korea attempted to launch another missile, but failed, according to the data of the USA air forces - the missile exploded nearly rights after the launch.
"I have noted the recent report", Mr Lu said, referring to the BBC interview. He then invaded South Korea to start the 1950-53 Korean War. The missile test prompted China to ban coal imports from its neighbour until the end of the year while saying it was time to restart talks.
North Korea's state television aired footage of a choral performance attended by Kim Jong Un, the elder Kim's grandson, on Sunday.
