South Korean President Moon Jae-in has dismissed the possibility of deploying nuclear weapons in his country, warning it could “lead to a nuclear arms race in northeast Asia.”

“I do not agree that South Korea needs to develop our own nuclear weapons or relocate tactical nuclear weapons in the face of North Korea’s nuclear threat,” he told CNN Thursday in his first televised interview since North Korea’s sixth nuclear test.
Though he was not supportive of deploying or pursuing nuclear weapons, Moon said South Korea “needs to develop our military capabilities in the face of North Korea’s nuclear advancement.”
Earlier this month, South Korea’s defense minister suggested it was worth reviewing the redeployment of US tactical nuclear weapons on the peninsula in order to deter threats from the North, something conservative US Sen. John McCain said should be “seriously considered.”
A recent Gallup Korea poll found 60% of respondents were in favor of South Korea having its own nuclear weapons, with 35% opposed.
“To respond to North Korea by having our own nuclear weapons will not maintain peace on the Korean Peninsula and could lead to a nuclear arms race in northeast Asia,” Moon said

US-South Korea relations

Next week, Moon will travel to New York for the United Nations General Assembly. His visit comes amid speculation over a growing rift between Seoul and Washington, after US President Donald Trump accused Moon of seeking “appeasement” with North Korea.
“South Korea is finding, as I have told them, that their talk of appeasement with North Korea will not work, they only understand one thing!” Trump tweeted earlier this month.
Moon was undeterred Thursday, saying there was no need to interpret Trump’s tweet “in a narrow way.”
“I believe what President Trump wanted to say was that, not only South Korea and the US, but also China and Russia all together need to respond very firmly against North Korea’s nuclear provocations,” he said.

Moon said just because the US and South Korea were currently pursuing a firm path of sanctions and military drills, the time for negotiations wasn’t over.
“This is in order to make the right conditions for dialogues and I would like to emphasize this,” he said.
But he added the new harsh UN sanctions, agreed to on Monday, would need to be properly enforced if they were to have any effect.
“There’s not just formal trade. There’s also informal trade that is going on and if China and Russia faithfully implement this resolution, I believe we can also be able to ban this informal trade,” he said. Continue reading.
