North Korea puts on a show for Day of the Sun

However, U.S. officials told The Associated Press on Friday that the Trump administration has settled on a policy that will emphasize on increasing pressure on Pyongyang with the help of China, North Korea's only major ally, instead of military options or trying to overthrow Kim's leadership.

North Korea displayed what appeared to be new long-range and submarine-based missiles on the 105th birth anniversary of its founding father, Kim Il Sung, on Saturday, as a nuclear-powered United States aircraft carrier group steamed towards the region. Gen. Douglas MacArthur, who commanded USA forces in Korea, wanted to attack the North with a nuclear weapon.

Chinese experts said they see little immediate possibility of hostilities breaking out, but warned that Beijing will respond harshly to any further North Korean nuclear tests.

North Korea said United States military bases in South Korea, and South Korea's presidential Blue House, would be "pulverised within a few minutes". Multiple senior members of the USA intelligence community confirmed to NBC that two naval destroyers with missile-launching capabilities have been stationed off the coast of North Korea in the event that President Kim Jong-Un follows through on the nuclear testing.

United States special forces, including Navy Seals, Delta Force and Green Berets, are already in South Korea for the annual Foal Eagle military exercise.

Differences from the Obama policy, if any, would likely be the level of appeal and pressure the USA puts on China to exercise more of its leverage as the North's main food and energy provider to rein in the regime.

Aides said there were contingency plans for the trip in case North Korea carries out a nuclear test. "Otherwise we're just going to go it alone, '" Trump said.

Huang said that from January 1 until that cut-off date, China had imported 2.67 million tons of coal from North Korea, 51.6% less than the same quarter in 2016.

Choe Ryong Hae, who some say is the second-most powerful official in North Korea, said in a speech that the country is ready to stand up to any threat posed by the United States.

OPINION: What's on Kim Jong-un's mind? .

Han refuted Trump's accusation that "North Korea is looking for trouble", claiming, "Trump is always making provocations with his aggressive words".

Pyongyang has said that their nuclear weapons development is created to counter U.S. policy that they believe is meant to invade the country and topple the government, namely supreme leader Kim Jong-un.

A White House foreign policy advisor today said that the U.S. is assessing military options in response to North Korea's weapons programs, saying another provocative test was a question of "when" rather than "if".

Chinese officials expressed concern over increasingly hostile relations between the United States and North Korea on Friday afternoon, telling China's state news agency that a full-scale war is closer than you might imagine.

KCNA said the Trump administration's "serious military hysteria" had reached a "dangerous phase which can no longer be overlooked".

The US says things must change as the superpowers lock horns over Syria.

Starting Monday, the Chinese flag carrier Air China will suspend flights from Beijing to Pyongyang, state broadcaster CCTV reported.

Trump has tweeted about North Korea several times this week. "China is willing to give support to all of them".

"Once a war rally happens, the result will be nothing but multiple-loss".

Pyongyang could use the parade as a show of strength in preference to a nuclear test, analysts said.

Wang said if the region is engulfed in conflict, the countries involved will have to "pay the corresponding price".

Earlier this week, North Korean officials threatened a pre-emptive strike if America begins to mobilise its nuclear weapons.
