He made the announcement in Geneva in his address at the UN-sponsored conference on Disarmament two days after his country detonated its sixth nuclear test explosion.
“I am proud of saying that just two days ago on Sept. 3, Democratic Peoples Republic of Korea successfully carried out hydrogen bomb test for an intercontinental ballistic rocket.
The test was carried out under our plan for building a strategic nuclear force,” Han told the Geneva forum.
He added, “the recent self-defence measures by DPRK, are a ‘gift package’ addressed to none other than the U.S.
“The U.S. will receive more ‘gift packages’ from my country as long as it relies on reckless provocations and futile attempts to put pressure on the DPRK.”
The diplomat said that military measures being taken by North Korea were “an exercise of restraint and justified self-defence right.”
He added that they were intended to counter “the ever-growing and decade-long U.S. nuclear threat and hostile policy aimed at isolating my country’’.
“Pressure or sanctions will never work on my country,” Han declared, adding, “DPRK will never under any circumstances put its nuclear deterrence on the negotiating table.”
On Monday, the White House said President Donald Trump had agreed “in principle” to scrap a warhead weight limit on South Korea’s missiles in the wake of the North’s latest test.
The U.S. accused North Korea’s trading partners of aiding its nuclear ambitions and said Pyongyang was “begging for war.”
