Outside the presidential office of South Korea, scores of civilians against the deployment of the U.S. Terminal High Altitude Area Defense (THAAD) missile interception system gathered on Friday afternoon.
China is by far North Korea's biggest trading partner, accounting for 92 percent of two-way trade previous year.
The Chinese media didn't run any commentaries with critical perspectives even after North Korea conducted its sixth nuclear test, allegedly of a hydrogen bomb, which could dramatically change the security situation on the peninsula.
The decision came three days after the communist North staged its latest and possibly most powerful nuclear test so far on Sunday.
U.S. Treasury Secretary Steve Mnuchin said he had an executive order ready for Trump to sign that would impose sanctions on any country that trades with North Korea, if the United Nations did not put new sanctions on it.
North Korea broke from its pattern of lofted launches last month when it fired a powerful new intermediate range missile, the Hwasong-12, over northern Japan.
Trump has repeatedly said all options are on the table in dealing with North Korea, including the military one.
The launchers were transported by U.S. Forces Korea vehicles to Seongju County under the cover of darkness early morning Thursday.
China's Foreign Ministry demanded Thursday that the Thaad system must be removed immediately. North Korea vehemently objects to military exercises on or near the peninsula, and China and Russian Federation have suggested the United States and South Korea halt their exercises to lower tension. Putin and Abe are set to meet later Thursday. There's no indication that a September 9 test would target Guam, but North Korea has threatened to attack Guam in the past, and a missile test near the island would be likely seen as a major provocation.
"Villagers and people coming to the village from across the country to block THAAD deployment protested for 18 hours on the road, but the village was completely devastated", they said in a statement.
Thousands of policemen were deployed to protect the Thaad systems which are four in number and are in addition to two other Thaad system batteries installed in the village in April which also birthed a similar clash.
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.
The deployment has drawn strong objections from China, which believes the system's radar could be used to look deeply into its territory and will upset the regional security balance. South Korea and the United States are technically still at war with North Korea after the 1950-53 Korean conflict ended with a truce, not a peace treaty.
