The United States and its ally South Korea were discussing on Monday sending more strategic US weapons to the Korean peninsula, a day after a US B-52 bomber flew over South Korea in response to North Korea’s nuclear test last week.
North Korea said it set off a hydrogen bomb last Wednesday, its fourth nuclear test since 2006, angering China, the North’s main ally, and the United States, which said it doubted the device was a hydrogen bomb.
In a show of force and support for allies in the region, the United States on Sunday sent a nuclear-capable B-52 bomber based in Guam on a flight over South Korea.
North Korea’s Rodong Sinmun newspaper, the mouthpiece of the ruling Workers’ Party, said the United States was bringing the situation to the brink of war.
South Korean media said the United States may send to South Korea B-2 bombers, nuclear-powered submarines and F-22 stealth fighter jets.
A South Koran defence ministry spokesman declined to give details.
“The United States and South Korea are continuously and closely having discussions on additional deployment of strategic assets,” the spokesman, Kim Min-seok, said.
China called for all sides to avoid raising tension.
“Safeguarding the peace and stability of northeast Asia accords with all parties’ interests,” Chinese Foreign Ministry spokesman Hong Lei said in response to a question about the US B-52 flight.
“We hope all parties can maintain restraint, proceed cautiously, and avoid successively escalating tensions.”
‘HIGHEST LEVEL READINESS’
The chairman of South Korea’s Joint Chiefs of Staff warned that North Korea was likely to carry out further “sudden provocations”, a South Korean defence ministry official said.
The commander of the 28,500 US troops in South Korea, General Curtis Scaparrotti, urged them to be vigilant.
“I want you to maintain the highest level readiness from a long-term view as joint military exercises are coming up,” Scaparrotti told US and South Korean forces on a visit to a base, a US military official said.
He was apparently referring to joint annual military exercises that usually begin in February or March and invariably provoke an angry reaction from North Korea.
On the diplomatic front, South Korea said its chief nuclear negotiator planned to meet his US and Japanese counterparts on Wednesday to discuss a response to North Korea, and the next day, he would meet China’s nuclear envoy in Beijing.
North Korea has been under UN Security Council sanctions since its first test of an atomic device. After its third test, in 2013, the Security Council took about three weeks to agree a resolution that tightened financial restrictions and cracked down on its attempts to ship and receive banned cargo.
South Korea and Japan used a military hotline for the first time after of North Korea’s test, South Korea’s defence ministry said, in a sign the North’s behaviour is pushing the two old rivals closer together.
South Korea has also resumed anti-North propaganda broadcasts through loudspeakers along the border, a tactic that the North considers insulting. It responded with artillery fire the last time South Korea used the speakers in August.
South Korea also said it would restrict access to the jointly run Kaesong industrial complex just north of the heavily militarised inter-Korean border to the “minimum necessary level” from Tuesday.
The complex, where South Korean factories employ North Korean workers, is an important source of revenue for the impoverished North.
