Death and state funeral of Kim Jong-il

China has confirmed that the North Korean leader, Kim Jong-un, has visited Beijing, where he met the Chinese president, Xi Jinping, and pledged his commitment to denuclearising the Korean peninsula.

Confirming several reports over the last two days, Xinhua state news agency said Kim had been in China on an "unofficial visit" from Sunday to Wednesday.

North Korean leader Kim Jong Un met senior South Korean government officials for the first time and said it is his “firm will to vigorously advance” inter-Korean ties and pursue reunification, the North’s official news agency said on March 5.

North Korea on Sunday accused the United States of trying to undermine an improvement in inter-Korean relations, while South Korean protesters tried to block senior North Korean officials on their way to the Pyeongchang Winter Games closing ceremony, Reuters reported.

North Korea's leader said he wants to boost the "warm climate of reconciliation and dialogue" with South Korea after his high-level delegation returned from a visit to the South, as his foes reiterated the need to keep up maximum pressure and sanctions, Reuters reported.

North Korean leader Kim Jong-un's sister will visit South Korea for the Winter Olympics in PeyongChang, the South Korean ministry of national unification said. Kim Yo-jong, who is the senior executive of the Korean Labor Party, will be part of a high-level delegation expected Friday in South Korea. She is responsible for the propaganda activity of the ruling party.

US President Donald Trump mocked his North Korean counterpart Kim Jong-un, saying he had a bigger nuclear button than his, announced the US press.

The United States has sanctioned two North Korean officials known for their role behind North Korean leader Kim Jong Un's missile program, according to a notice posted to the U.S. Treasury Department's website on Tuesday, Reuters reports.

The men, Kim Jong Sik and Ri Pyong Chol, are known as two of the three people behind Kim's banned rocket program.

President Donald Trump said on Nov. 12 that it was possible he could be friends with North Korean leader Kim Jong Un one day and that it would be "very, very nice" but he was not sure that it would happen.

A total of 100 workers died in the collapse of a still unfinished tunnel in the DPRK, where North Korea's leader Kim Jong un tests his nuclear weapons, reports Japanese media quoted by Bild.

North Korea accused the United States of having declared war on them, the BBC reported.

According to the Foreign Minister of DPRK Ri Yong-ho, this gives grounds for his country to take down US bombers, "even when they have not yet entered our airspace." He made his statement in New York at the UN General Assembly.
