"When it comes to the upcoming Supreme People's Assembly meeting, the main points are the North's policies on the economy, policies on nuclear weapons against South Korea, and whether there will be change in the prime minister position. And if there is a change, it will be interesting to see whether Jang Song Thaek will be the new prime minister, who directs the economy."
The South Korean Unification Ministry said that the safety of their citizens who work at the Kaesong Industrial Complex is "their first priority" after North Korea threatened over the weekend to close the facility and warned that the Korean Peninsula had entered "a state of war."
Speaking on Monday in Seoul, the minstry's spokesperson, Kim Hyung-suk, said they were working 24 hours a day to prepare for any likely scenario regarding the complex, which is located within North Korea, a few miles (kilometres) north of the Demilitarised Zone (DMZ).
As tensions have continued to escalate, North Korea threatened on Saturday to close down the Kaesong Industrial Complex.
North Korean state broadcaster said in a televised statement the government will "shut down the zone without mercy" should what it called "the puppet group" - a reference to the United States and South Korea - "seek to tarnish" the country's image.
It is thought that Pyongyang threatened to shut down the jointly run Kaesong Industrial Park to express anger over media reports suggesting the complex remained open because it was a source of hard currency for the impoverished North.
The plant remained opened on Monday as employees made their way from South Korea.
North Korea is expected to hold its Supreme People's Assembly meeting Monday, and the South Korean Unification Ministry encouraged the North not to act in provocative manner towards the international community.
"North Korea should not act against the repeated warnings from the international community, but we hope the North takes the virtuous path by recognising the will of the international society to cooperate to assist North Korea's transformation," said Kim Hyung-suk, the unification spokesperson.
A professor at the University of North Korean Studies, Yang Moo-jin, outlined the main points of interest he expected to hear from the North Korean Assembly, which included more economic and nuclear policies and whether Kim Jong Un's uncle, Jang Song Thaek, would be named the country's new prime minister and play a leading role in economic reform.
North Korea has been infuriated by South Korea-US joint military drills and new United Nations sanctions over its recent nuclear test.
A top North Korean decision-making body issued a pointed warning Sunday, saying that nuclear weapons are "the nation's life" and will not be traded even for "billions of dollars."
The comments came in a statement released after North Korean leader Kim Jong Un presided over the plenary meeting of the central committee of the ruling Workers' Party.
The meeting, which set a "new strategic line" called for building both a stronger economy and nuclear arsenal, comes amid a series of near-daily threats from Pyongyang in recent weeks, towards South Korea and US.
Seoul residents reacted with concern to the recent announcements from the North.
"I hope that the North gives up on nuclear development and only focuses on economic development. I hope our government encourages the North to go in that direction," said one resident.
