In a statement carried by the regime's state news agency, North Korea's foreign ministry said Trump (quote) "laid bare his true nature as destroyer of world peace and stability and begged for a nuclear war on the Korean peninsula".
The paper denounced the US president's Asia trip as "a warmonger's trip for confrontation with the North", "an old miser's trip to sell arms", and "a chief terrorist's trip for self-destruction".
Trump said in a speech at South Korea's parliament Wednesday, "Currently stationed in the vicinity of this peninsula are the three largest aircraft carriers in the world loaded to the maximum with magnificent F-35 and F-18 fighter jets".
Trump met with Japan and South Korea officials early last week.
South Korea's navy will join a four-day exercise involving three U.S. aircraft carriers to be held hold off the east coast of the Korean Peninsula from Saturday, the South Korean military said Friday.
This comes as Trump said on Thursday that he wants Russia's help in getting North Korea to give up its nuclear weapons.
The battle groups of the USS Ronald Reagan, the Theodore Roosevelt and the Nimitz will successively enter the exercise area during the drills that run until Tuesday, South Korea's Joint Chiefs of Staff said.
Also to be mobilized are 11 U.S. Aegis ships and seven South Korean warships.
Instead the threat "pushes us to speed up the efforts to accomplish the great cause of completing the state nuclear force", the statement said, dismissing Trump's tour of the region as a "business trip". The Aegis technology refers to missile tracking and guidance.
Nuclear-armed North Korea regularly denounces such military drills as rehearsals for invasion and sometimes conducts its own military manoeuvres or missile tests in response.
It has repeatedly threatened to launch ballistic missiles into the waters around the USA territory of Guam.
North Korea also announced that they will be closely monitoring the President's time in Asia.
