Diplomacy between North and South has zigzagged from conciliatory to bellicose. 1  The North Korean army has declared invalid the armistice agreement that ended the Korean War in 1953, the official newspaper of the country's ruling Workers' Party said Monday.

It was the end of the longest negotiated armistice in history: 158 meetings spread over two years and 17 days. That evening at 10 p.m. the truce went into effect. The Korean Armistice Agreement is somewhat exceptional in that it is purely a military document—no nation is a signatory to the agreement.

The Korean War armistice. Read more about sharing. The 1950-53 Korean War ended in an armistice, with neither side able to claim outright victory. Decades on, the truce is still all that technically prevents North Korea and the US - along with its ally South Korea - resuming the war, as no peace treaty has ever been signed.

(on Archives.gov) This armistice signed on July 27, 1953, formally ended the war in Korea. North and South Korea remain separate and occupy almost the same territory they had when the war began. The Korean War, which began on June 25, 1950, when the North Koreans invaded South Korea, officially ended on July 27, 1953.

Meanwhile, American officials worked anxiously to fashion some sort of armistice with the North Koreans. The alternative, they feared, would be a wider war with Russia and China–or even, as some warned, World War III. Finally, in July 1953, the Korean War came to an end.

On June 25, 1950, the Korean War began when some 75,000 soldiers from the North Korean People’s Army poured across the 38th parallel, the boundary between the Soviet-backed Democratic People’s Republic of Korea to the north and the pro-Western Republic of Korea to the south. This invasion was the first military action of the Cold War.

The armistice is still the only safeguard for peace on the Korean peninsula. The agreement provided for: A suspension of open hostilities. A fixed demarcation line with a 4km (2.4 miles) buffer zone - the so-called demilitarisation zone. A mechanism for the transfer of prisoners of war.

An armistice is a modus vivendi and is not the same as a peace treaty, which may take months or even years to agree on. The 1953 Korean War Armistice Agreement is a major example of an armistice which has not been followed by a peace treaty. Armistice is also different from a truce or ceasefire, which refer to a temporary cessation of hostilities for an agreed limited time or within a limited area.

The Hague II (1899) Treaty, says If [the armistice's] duration is not fixed, the parties can resume fighting (Article 36) as they choose, but with proper notifications. This is in comparison to a fixed duration armistice, where the parties can renew fighting only at the end of the particular fixed duration.
