A top South Korean official has told MPs North Korea could have up to 60 nuclear weapons.

In Seoul’s first public comment about the size of the North’s secretive weapons arsenal, unification minister Cho Myoung-gyon told parliament the estimates range from 20 bombs to as many as 60.

He was responding to a question by an MP, and said the information came from the intelligence authorities.

Mr Cho may have unintentionally revealed the information.

His ministry said the comments did not mean that South Korea would accept North Korea as a nuclear state, suggesting Seoul’s diplomatic efforts to rid the North of its nuclear programme would continue.

The South Korean assessment on the North’s arsenal is not much different from various outside civilian estimates largely based on the amount of nuclear materials that North is believed to have produced.

According to South Korean government reports, the North is believed to have produced 50kgs (110lbs) of weaponised plutonium, enough for at least eight bombs.

Stanford University scholars, including nuclear physicist Siegfried Hecker who visited North Korea’s centrifuge facility at Nyongbyon in 2010, wrote earlier this year that North Korea is estimated to have a highly enriched uranium inventory of 250 to 500kgs (550 to 1,100lbs), sufficient for 25 to 30 nuclear devices.

Many foreign experts say North Korea are likely running additional secret uranium-enrichment plants.

The North entered talks with the United States and South Korea earlier this year, saying it is willing to negotiate away its advancing nuclear arsenal.

Nuclear diplomacy later stalled due to suspicions over how sincere North Korea is about its disarmament pledge, but US Secretary of State Mike Pompeo is to visit Pyongyang this month to set up a second summit between US president Donald Trump and North Korean leader Kim Jong Un.

On Tuesday, North Korea said declaring the end of the 1950-53 Korean War “can never be a bargaining chip” for getting the North denuclearised, and said the country “will not particularly hope for it” if the United States does not want the end of war.
