President Moon Jae-in says he called for a declaration to end the 1950-53 Korean War based on his pride in South Korea's defense readiness.
He spoke on Friday at a ceremony to mark the country's Armed Forces Day.
Moon made the proposal last week during his UN General Assembly address to declare an end to the war that ended with an armistice with related parties.
"I have pride in our solid security posture. I have proposed adopting an end-of-war declaration and opening a new era of conciliation and cooperation with the international community based on such trust and pride."
Moon's message comes amid a sticky situation on the Peninsula following a series of missile launches by North Korea. while it continues to issue statements regarding the development of inter-Korean relations.
Moon said as the commander-in-chief, his top responsibility is to establish peace on the Korean Peninsula.
He added that the government will respond sternly to any threats however, he did not mention North Korea's missiles directly.
"The first and most important responsibility as commander-in-chief is establishing lasting peace on the Korean Peninsula, and maintaining it. It is also the mission of the military. The government and military will sternly respond to any act that threatens people's lives and safety."
Moon said that South Korea will further boost its defense posture, and will develop more powerful missiles after Seoul and Washington agreed to scrap missile guidelines.
He also highlighted the recent military feats such as the testing of a submarine-launched ballistic missile and development of a prototype for the KF21 fighter jet.
Moon noted the increase to next year's defense budget proposed at roughly 47.6 billion U.S. dollars.
That's up 37 percent since 2017 the start of Moon's term.
The president also stressed the importance of protecting troops' human rights likely in response to recent sexual and physical abuse cases saying that it's a shortcut to becoming a strong military.
