Chinese foreign ministry spokesman Geng Shuang also reiterated Beijing's opposition to South Korea's deployment of the US Terminal High-Altitude Area Defence System, also known as THAAD, which is meant to protect against North Korean missile attacks.
In the rural town of Seongju, thousands of police officers in riot gear swarmed some 400 protesters who since Wednesday night had been occupying a road leading to a former golf course where the Terminal High-Altitude Area Defence System is installed.
A THAAD battery normally consists of six launchers, but only two have been operational so far at the site in rural Seongju. Further protests have been called for Thursday by activists opposed to the presence of THAAD.
The Nuclear Safety and Security Commission (NSSC) said it had been conducting tests on land, air and water samples since shortly after the North Korean nuclear test on Sunday. He said it "offers a genuine way to defuse the tensions and a step-by-step settlement".
Moon earlier called for a ban on overseas North Korean workers, who are a key foreign currency source for the North, but Putin said problem should be solved diplomatically, according to Seoul's presidential office.
South Korean President Moon Jae In stressed that diplomacy, not war, was the way to deal with the North Korean nuclear threat, even as the South yesterday completed the deployment of a missile shield.
His remark was made at the Seoul Defense Dialogue, an worldwide meeting in Seoul.
Throughout the week, South Korean officials have warned the North could launch another intercontinental ballistic missile, in defiance of U.N. sanctions and amid an escalating standoff with the United States.
The US President reportedly issued the order to his top military generals last month after North Korea threatened to fire a ballistic missile towards the US territory of Guam.
He also accused Japan and South Korea of showing "utterly disgusting" and "despicable behavior" by taking the lead in seeking new sanctions.
North Korean leader Kim Jong-un is playing an unprecedentedly risky game with nuclear and missile tests. Kang says the regime picks public holidays for weapons tests to boast to the world, but also to serve as propaganda to bond North Koreans.
Abe will meet Putin on Thursday.
Like many countries, North Korea likes to celebrate independence or founding days with parades and proclamations, but Pyongyang likes to add dramatic gestures against imperialism, particularly ones that showcase its military might.
