In the aftermath of that thinly veiled threat, a spokesman for North Korea's foreign ministry said: "We will hold the United States wholly accountable for the catastrophic consequences to be entailed by its outrageous actions". Some argue that China could exert much more pressure since it supplies most of North Korea's food and energy.
The appointment of a new State Security Minister, who is in charge of administering the North Korean secret police, will probably be included in the session's agenda as the former minister Kim Won-hong was ousted in February, Efe news reported. But he also likened Mr Kim to a "maniac", and said he would get China to "make that guy disappear in one form or another".
He added: "If the U.S. dares opt for a military action, crying out for "pre-emptive attack" and "removal of the headquarters", the DPRK (the formal name for North Korea) is ready to react to any mode of war desired by the USA".
The rogue state has a history of launching missiles and taking provocative actions on the anniversary, and satellite imagery suggests Kim Jong-un might take the opportunity to flex his military muscles on April 15.
The North may stage a "strategic provocation" to mark key political dates this month, Kim said, adding that Wu's visit would serve as a "strong warning" against Pyongyang. He saw some images of gassed children, and the next thing we knew, we were engaged in an act of war against another sovereign nation, with no explanation of what might be accomplished by the missile salvo, no indication of any plan for what might follow.
President Donald Trump promised "pleasant surprises" from planned renegotiations of the decades-old North American Free Trade Agreement.
President Donald Trump, fresh from a missile strike on Syria that was widely interpreted as putting Pyongyang on warning, has asked to be provided with a range of options for eliminating the North's nuclear capabilities.
However, the U.S. strike against Syria was unlikely to deter Kim Jong-un from developing his nuclear weapons program, former Pentagon official Daniel Goure told United States news channel CNBC.
"It's quite possible it could be a very intense, bloody war", he said.
"This goes to prove that the USA reckless moves for invading the DPRK have reached a serious phase", a spokesman for the North's foreign ministry said according to state news agency KCNA.
That means it could hit South Korea; another archenemy, Japan; or potentially even the continental United States in a few years.
Sen. Cory Gardner on Monday said the recent deployment of a Navy strike group toward the Korean Peninsula is an important "show of force" and that North Korean leader Kim Jong-un can not be ignored.
A Chinese envoy held talks in South Korea on Monday on North Korea's increasingly defiant weapons program as a U.S. Navy strike group headed to the region amid concerns that Pyongyang may be preparing a fresh nuclear test.
