So far, North Korea has not come up with an official reaction to the U.N. decision, but has long threatened to react head-on to further UNSC sanctions.

"If the United States sticks to its military adventurism against us and super-intensive sanctions schemes, we will respond with a stern action of justice as we have already declared," North Korea's foreign ministry said in a statement on July 30 following its second ICBM test two days earlier.

The Sunday edition of the Rodong Sinmun, a mouthpiece newspaper for the ruling Workers' Party of Korea, warned in an article that "The day the US dares tease our nation with a nuclear rod and sanctions, the mainland US will be catapulted into an unimaginable sea of fire."

The article was printed before the final adoption of the UNSC resolution, but it could still portend to North Korea's fierce reaction to the latest sanctions drafted by the US.

"Regardless of how intense the anti-North sanctions contained in the resolution are, the North will probably come up with a hard-line response as it has warned of a confrontation with the U.S.," Prof. Kim Yeon-chul of Inje University said.

"At this moment, a firm-action-to-firm-action stance seems to be unavoidable," the professor predicted.

The launch of additional ICBM-type projectiles could be one provocation North Korea can opt for in protest given the intense impact its latest two launches have drawn.

Even from inside the US, the latest missiles, called Hwasong-14 ICBMs by the North, are estimated to have a range capable of hitting the eastern part of the US mainland. This caused the US to move quickly to find ways to address the threat.

Another possibility could be a warhead re-entry test or an airborne explosion test, according to experts on North Korean issues.

"Sticking to its own timetable chronicling the ICBM (test) and fitting of a nuclear warhead, North Korea would immerse itself in increasing its bargaining power," Choi Kang, vice head of the Asan Institute of Policy Studies, said. 

Throughout August, North Korea may also venture into low-intensity provocations as a pretext for deterrence against the Ulchi-Freedom Guardian (UFG), a regular exercise between Seoul and Washington, that will kick off late this month in South Korea, according to Kim Dong-yub, a professor at the Institute for Far Eastern Studies affiliated with Kyungnam University.

"North Korea would have a more diversified range of options from which it can choose from as the sanctions resolution came ahead of the joint South Korea-US military exercise," he noted. 

In reaction to past joint military exercises, North Korea carried out missile launches or live-fire artillery drills, claiming that they were responding to the allies' war rehearsals.

North Korean leader Kim Jong-un himself has also warned of more provocations in the pipeline after personally inspecting the country's first Hwasong-14 launch on July 4. He said North Korea will send similar "gift packages" of different sizes to Washington going forward, although he did not provide specific plans.

Local experts, meanwhile, pointed to the new resolution omitting a ban on oil exports to North Korea, predicting that it may fall short of dealing a fatal blow to the North Korean regime. 

"The resolution was something of a face-saving arrangement between the US and China and the exclusion of cutting off the crude oil supply is very regrettable," Choi of the Asan Institute of Policy Studies said. "I am not sure if North Korea would feel crushed." 

Yang Moo-jin, a professor at the University of North Korean Studies, said that in the absence of an action on the crude oil front, The final success of the resolution may depend on implementation by China and Russia. (Yonhap)
