South Korean President Park Geun-hye on Wednesday urged China to help ensure that North Korea "feels pain" over its recent nuclear test, as the worldwide community looks to Beijing to exert its significant influence over Pyongyang.

At the initiative of the United States, the U.N. Security Council is proceeding with work to draft a resolution aimed at imposing sanctions on North Korea.

China angrily criticized North Korea over last week's nuclear test, but is seen as reluctant to impose extremely harsh sanctions against the North Korea.

U.S. experts have rubbished the latest claims by North Korea on its booming nuclear prowess stating the latest bomb testing.

The North is blasting back its own propaganda, and South Korea's Newsis website reported the reclusive country also released 10 large balloons into South Korea on Wednesday that carried leaflets saying: "Let's knock down the gang of Park Geun-hye ... as if we beat a mad dog!" and urging the U.S.to "Give up your anachronistic hostile policies against Chosun (North Korea) right now!"

Relations between China and South Korea have steadily improved under Park and Xi, who has visited the South but not the North. But Beijing has maintained its trade ties and aid delivery to North Korea, so that its nuclear-armed neighbor remains stable.

The sanctions are mandated against any country, business or individual that materially contributes to North Korea's nuclear and ballistic missile development, imports luxury goods into North Korea, or engages with Pyongyang in money laundering, the manufacture of counterfeit goods, or narcotics trafficking, according to the legislation. In August 2015, the two countries exchanged artillery fire, while North Korea's leader Kim Jong Un declared a "quasi-state of war".

In the wake of the nuclear test a week ago, the two Koreas have settled into a Cold War-era stand-off.

"I believe the Chinese government will not allow the situation on the Korean peninsula to deteriorate further".

People watch a TV news program showing North Korea's announcement, at the Seoul Railway Station in Seoul, South Korea, Wednesday, Jan. 6, 2016. "If not, it could be part of a scouting mission before North Korea devises a plan to target South Korean loudspeakers".

The three nations are also expected to discuss ways to secure China's cooperation in holding the North responsible for the nuclear provocation.

In an annual press conference, Ms Park said the global community's response "must differ from the past", without giving details, and that China's help was crucial.

The bill summary and status of the North Korea Sanctions Enforcement Act of 2015, passed by the US House of Representatives. But despite Xi's proclamation that the China-South Korea relationship "has become the best-ever national relationship in history", Seoul is not having much luck changing China's traditional approach to North Korea. "This was a demonstration of the ironclad U.S. commitment to our allies in South Korea and in Japan", Adm. Harry Harris, commander of the U.S. Pacific Command, said in a statement.

Describing the resumed propaganda broadcasts as the most effective and powerful tool of psychological warfare, Park indicated that the continued broadcast for the time being.
