North and South Korea hold high-level talks in Kaesong

North Korean leader Kim Jong Un made an oblique claim on Thursday to the development of a hydrogen bomb although the Communist nation’s technical capacity for developing such a device was doubted by both US and South Korean officials.

But South Korea stopped the broadcasts and North Korea apologized after Kim Kwan-jin, South Korean President Park Geun-hye’s national security adviser, and Hwang Pyong-so, a top military aide to Kim Jong-un, held negotiations in late August.

Improving relations with Seoul is a priority for young North Korean leader Kim Jong Un, who likely wants tangible diplomatic and economic achievements before a convention of the ruling Workers’ Party in May, said Koh Yu-hwan, a North Korea expert at Seoul’s Dongguk University.

North Korea is critical of the annual military drills between South Korea and the United States, calling them rehearsals for war.

The hydrogen bombs use fusion that results in a blast that is more powerful than a basic atomic bomb, BBC News noted Thursday.

The U.S. State Department repeated a call on North Korea to comply with its global obligations and abandon all nuclear weapons.

White House press secretary Josh Earnest said, “we certainly are concerned about the policies and intent and destabilizing actions of the North Korean regime”.

South Korean news agency Yonhap reported the leader of the band, Hyon Song Wol, was in Beijing as the group headed for a luxury hotel.

In November, a spokesman for South Korea’s Unification Ministry indicated topics would include South Korean demands for regular family reunions as well as North Korea’s desire to resume tourism to the Mount Kumgang resort in the north.

The North has threatened to ruin its important ally, America, in a sea of fires and the South. But they also noted that North Korea has repeatedly vowed to improve the quality of its nuclear weapons.

But outside observers were skeptical, saying that such an advance in the country’s nuclear technology seemed unlikely.

The Pyongchon Revolutionary Site is where Kim Il-sung, Kim Jong-un’s grandfather, first established a North Korean weapons factory in October 1945.

According to analysts and insiders, any discussion on North Korean human rights will happen over the objections of China and Russian Federation.

In fact, North Korea appears to have disproved the first claim with a failed missile launch from a submarine last month.

Earlier, North Korea has tested three atom bombs, which rely on nuclear fission.

“Whether North Korea can make nuclear weapons using tritium is unknown although we believe that it remains a technical problem North Korea still needs to solve”.

“Tritium would enable nuclear weapons designs that could have a greater explosive yield than weapons made from only plutonium or weapon-grade uranium”, they wrote.
