South Korea said Thursday that North Korea's upcoming parliamentary meeting will be used as a venue to reassert its leader Kim Jong-un's one-man rule and give him another new title as the head of state.

Next Wednesday, North Korea plans to convene a major meeting of the Supreme People's Assembly in a follow-up to the party congress in May, an event aimed at helping reaffirm the leader's unfettered hold on power.

Seoul's unification ministry said that the communist country is likely to conduct an overhaul of Cabinet organs and a lineup of government officials, and take steps to get approval for decisions reached at the congress of the Workers' Party of Korea.

"There is a possibility that the country could change the leader's current title of the first chairman of the National Defense Commission as he was elected the chairman of the WPK at the congress," the ministry said in a statement.

The SPA, the legislative body of the reclusive country, rubber-stamps decisions by more powerful organizations such as the WPK and the NDC.

Analysts said that the SPA's session will serve as an event to complete the coronation of the North's leader who took power in late 2011 following the sudden death of his father Kim Jong-il.

At the ruling party's congress, Kim made it clear that he will "permanently" defend the pursuit of his signature policy of developing nuclear weapons and boosting the country's moribund economy.

The North's leader held the title of the first secretary of the WPK before the party congress. His two other titles are the first chairman of the NDC, which was bestowed at the SPA session in 2012, and the supreme commander of the Korean People's Army.

"Through the SPA meeting, North Korea is expected to complete the establishment of the power structure to build the Kim's one-man leadership," the ministry said.

On Wednesday, North Korea fired off two Musudan intermediate-range ballistic missiles in what could be a showoff of its nuclear and missile capabilities ahead of the SPA session.

What North Korea called a successful launch of one mid-range missile raises concerns about a breakthrough made in the North's nuclear and missile programs. Pyongyang is seeking to develop a nuclear-tipped intercontinental ballistic missile capable of hitting targets in the U.S. mainland.

A group of North Korean defectors on Thursday said North Korea may propose holding talks between the two Koreas' parliamentary speakers at the SPA meeting.

"North Korea is seeking to make the proposal for parliamentary dialogue one of the main agenda items for the SPA session," Kim Heung-kwang, executive director at NK Intellectuals Solidarity, told reporters, citing internal information from the North.

Kim Chong-in, the interim head of the main opposition Minjoo Party of Korea, on Tuesday proposed to South Korea's parliamentary speaker that the two Koreas need to hold parliamentary talks.

But the unification ministry cast a cautious view about such a proposal, saying that now is the time to focus on pressing the North to give up its nuclear weapons. (Yonhap)
