In the first comments on Mr Trump's visit by a North Korean official, a Pyongyang foreign ministry spokesman said it was a "warmonger's visit for confrontation to rid" North Korea of its self-defensive nuclear deterrence, the state-run KCNA news agency reported.
South Korea will join three USA aircraft carrier strike groups in a joint drill scheduled for November 11 to 14, the South's military said on Friday.
The three carriers will be likely together in the drills around Monday, according to a South Korean military official, who didn't want to be named, citing office rules.
Trump also warned North Korea not to underestimate the United States in a speech to the South Korean parliament on Wednesday, while offering leader Kim Jong-Un a better future if he gives up his nuclear ambitions.
"The strike force plans to conduct air defense drills, sea surveillance, replenishments at sea, defensive air combat training, close-in coordinated maneuvers, and other training", said a statement from the Navy's 7th Fleet, which is responsible for monitoring the Pacific including North Korea.More news: Trump touts his dealmaking skills as solution to South China Sea dispute

The exercise comes after the two countries agreed in talks between their respective defense ministers last month to expand the rotational deployment of US strategic military assets to the Korean Peninsula to better cope with North Korean provocations. The U.S. carriers will also participate in separate exercises with three Japanese destroyers on Sunday, according to Japan's Maritime Self-Defense Force.
It is the first such U.S. triple-carrier drill in the region for a decade.
The region, he added, must "stand united in declaring that every single step the North Korean regime takes toward more weapons is a step it takes into greater and greater danger".
Trump has been working to rally global pressure against North Korea's nuclear weapons program on a trip to Asia.
The harsh words between the leaders have escalated in recent months after North Korea threatened to launch missiles toward the USA territory of Guam.
Ever since US President Donald Trump and North Korean leader Kim Jong-un's feud broke out in public, barbs have been exchanged nearly regularly between the two nations.
