SEOUL (AFP) - North Korea's top state newspaper gave the South's President Moon Jae In a "fail" grade on Friday (Aug 18) for his first 100 days in office, dismissing his proffered olive branches as "hypocrisy".
Mr Moon, elected to replace impeached president Park Geun Hye, came into office in May and has since had to deal with tensions over the North's missile and nuclear programmes.
Pyongyang carried out its first successful tests of an intercontinental ballistic missile (ICBM) last month, apparently bringing much of the United States mainland within its reach.
At a briefing on Thursday to mark his 100th day in office, Mr Moon insisted there will be no second Korean war but urged the North to stop further nuclear and missile tests, warning Pyongyang to end its "dangerous gamble".
North Korea's Rodong Sinmun, the official mouthpiece of the ruling Workers' Party, responded on Friday with a withering commentary, saying that the performance sheet for Mr Moon's 100 days was "poor and very disappointing".
It did not name Mr Moon, describing him only as the "current power holder".
Relations between the two were "an absolute fail", it added, saying that while Mr Moon spoke of dialogue and implementing North-South agreements, his actions moved in the opposite direction.
"The south authorities' utterances about improving intra-Korean ties turned out to be nothing but hypocrisy," it said.
"The south's power holder says he is pushing for sanctions and pressure while seeking to open dialogue at the same time. This is an unpardonable plot toeing the US line to suffocate the DPRK," it said, using the abbreviation of the North's official name.
"Dialogue and sanctions simply cannot go together," it asserted.
Mr Moon is enjoying strong ratings in the South, with opinion polls putting his approval figures in the 70s.
North Korea's ICBM tests sparked weeks of sabre-rattling with Washington, with Pyongyang threatening to fire a salvo of rockets towards the US territory of Guam. US President Donald Trump has warned of "fire and fury" and said Washington's weapons were "locked and loaded".
Tensions have since eased with the North's leader Kim Jong Un saying he would watch the "Yankees" for a time before deciding whether to proceed with the Guam plan.
But the atmosphere is likely to worsen again next week when the US and South Korea kick off their annual Ulchi Freedom Guardian military drills.
Pyongyang views them as a highly provocative rehearsal for an invasion of its own territory, and regularly carries out counter-actions of its own, such as missile launches.
