South Korea would neither develop nor own nuclear arms, South Korean President Moon Jae-in said on November 1, 2017.

During his second state of the nation at the National Assembly, Moon made the remarks amid conservative opposition parties' call to redeploy US tactical nuclear weapons.

The opposition parties have recently been calling for a redeployment of US tactical nukes to counter North Korea's growing asymmetrical weapons of war. Such a call quickly gained momentum after North Korea staged its sixth and most powerful nuclear test so far in September.

Head of the main opposition Liberty Korea Party Hong Joon-pyo even went to the US last week to convince US policymakers to consider redeploying US tactical nuclear arms to South Korea. However, President Moon said establishing peace is the government's principal goal.

"What we want to realize is peace on the Korean Peninsula. Therefore, there can never be any armed conflict on the Korean Peninsula under any circumstances. There cannot be any military action on the Korean Peninsula without a prior consent of the Republic of Korea," the president said.

However, the president vowed maximum retaliation against any military provocation from the North.

"To this end, we must secure overwhelming power. We will also closely work with the international community, based on the strong Korea-US alliance," Moon said.

He also stressed the importance of maintaining what he has called maximum pressure and sanctions on the North as a way to bring North Korea into the dialogue.
