U.S. President Donald Trump has said South Korea and the United States remain "united" in a steadfast alliance, calling their bond a "pillar of peace and stability" across the Indo-Pacific, as he released a message marking the 73rd anniversary of the signing of the Korean War armistice.

On its website on Monday, the White House posted the message honoring the sacrifices of American troops who fought alongside South Korean and U.N. forces to defend South Korea during the 1950-53 war, the first major armed conflict of the Cold War.

"More than seven decades after the war, the United States of America and the Republic of Korea remain united in a steadfast alliance, tested by shared sacrifice, and bound by an abiding love of freedom," Trump said in the message.

"That bond serves as a pillar of peace and stability across the Indo-Pacific, a solemn vow to our allies throughout Asia that we will stand with them against the forces of evil and oppression -- a threat to world peace that endures to this very day," he added.
