SEOUL, May 24 (Xinhua) -- The South Korean authorities said Thursday that the planned dismantlement of a nuclear test site by the Democratic People's Republic of Korea (DPRK) will be the first step toward complete denuclearization on the peninsula.

The comment was made at a permanent committee meeting of the National Security Commission (NSC), chaired by Chung Eui-yong, top security advisor for South Korean President Moon Jae-in, according to the Blue House.

The committee members assessed the planned dismantling of the Punggye-ri nuclear test site by the DPRK and discussed follow-up measures.

Pyongyang has invited journalists from China, Russia, the United States, Britain and South Korea to witness on Thursday the closure of the test site, where all of the DPRK's six nuclear tests were conducted.

Furthermore, the NSC members also discussed various ways to support the highly-expected DPRK-U.S. summit, which is scheduled between top DPRK leader Kim Jong Un and U.S. President Donald Trump on June 12 in Singapore.?
