South Korea decided to set up the standing committee and secretariat of its National Security Council (NSC) to regularize security meetings amid rising threats from the Democratic People's Republic of Korea (DPRK), the country's top presidential aide in charge of security and foreign affairs said Friday. "The NSC's standing committee and secretariat will be established after revising the NSC act," Ju Chul-ki, chief presidential secretary for foreign affairs and security, said at an emergency briefing, according to the statement by the presidential office Cheong Wa Dae. Ju said that tensions escalated on the Korean Peninsula as the DPRK threatened to strike South Korea without any advance notice, noting that grave situations lasted after the execution of Jang Song-Thaek, uncle of DPRK leader Kim Jong Un.
