It is the first time that North Korea has held Moon personally responsible for his handling of the North-South relations since he came to power about 100 days ago, Xinhua news agency reported.
"There is no military solution for this conflict, it must be worked out via negotiations", Chancellor Angela Merkel said in a YouTube interview, criticizing what she called escalating rhetoric by "all sides". "The alternative would have been both catastrophic and unacceptable!" But it is also an issue between the North and the United States.
But as State Department spokesperson Heather Nauert said on Tuesday, the USA has no plans of stepping them down. Moon wants to engage the North.
In a meeting with Moon on Monday, Dunford reiterated the U.S.'s commitment to protect South Korea.
Moon, who took office on May 10 after a snap election after the ouster of his conservative predecessor over a corruption and influence-peddling scandal, said Seoul is in close communication with Washington over the North Korean problem.
Mr Trump tweeted on Wednesday that Kim Jong Un had: "made a very wise and well-reasoned decision", amid indications that he does not immediately plan to fire multiple missiles toward Guam.
Trump's administration has consistently said military action is on the table and the president has even suggested he's willing to take unilateral action against Pyongyang if it continues to threaten the United States.
He also commented that "the USA sought to put maximum pressure and sanctions through the latest UN Security Council resolution", while at the same time it is "seeking unilateral measures".
"If North Korea provokes again, it will face with much harsher sanction and won't stand it in the end".
However, the US' top military official, General Joseph Dunford, chairman of the Joint Chiefs of Staff, said in Beijing: "Any military action taken on the Korean peninsula would be in consultation with our allies".
And U.S. Vice President Mike Pence again stated that "all options" toward North Korea remain for consideration during his visit to South America.
Moon said he would be ready for dialogue once the isolated nation stops its provocations, adding that there was no rush.
North Korea on Friday slammed South Korean President Moon Jae-in for his policy towards Pyongyang and his cooperation with the US.

Technical ability to place a nuclear warhead on an ICBM "will not be tolerated" On August 17, President Moon Jae drew a "red line" with regard to North Korea's nuclear and missile program, issuing a stern warning to the government in Pyongyang.
USA officials and experts say the North has demonstrated major progress toward that goal with dozens of missile tests, including two ICBM launches last month.
