The Khitomer Accords refers to two historic treaties signed between the United Federation of Planets and the Klingon Empire. The Accords receive their name for the Klingon colony of Khitomer where the first peace treaty was signed at the Khitomer Conference in 2293. (TOS movie: Star Trek VI: The Undiscovered Country; DS9 novelization: The Way of the Warrior; ST reference: Federation: The First 150 Years)
In 2370, retired Starfleet Captain Montgomery Scott devised a plan to take a B'rel-class Klingon bird-of-prey, the Bounty 2, back in time and rescue his former commanding officer, James T. Kirk, Scott had the forethought to utilize the shuttlecraft Goddard rather than the Bounty 2 to approach the USS Enterprise-B, since a Klingon ship that deep in Federation territory would likely disrupt the tenuous peace of the recently signed Khitomer Accords. (Star Trek novel: Engines of Destiny)
After Starfleet refused to participate in the invasion of the Cardassian Union in 2372 and the Federation Council condemned it, Chancellor Gowron withdrew the Empire from the Accords. (DS9 novelization: The Way of the Warrior)
Among the agreements of the Accords was a provision stating that diplomatic pouches were not subject to searches by security or military personnel; Ambassador Worf utilized this privilege to carry weaponry and classified Starfleet Intelligence equipment into the Klingon Great Hall. 
Following the formation of the Typhon Pact, the Federation and Klingon Empire invited the Imperial Romulan State, Cardassian Union, Ferengi Alliance and Talarian Republic to join in an expansion of the Accords to establish a strong counter-alliance to the Pact. Empress Donatra of the Imperial Romulan State and Ferengi Grand Nagus Rom immediately accepted the invitation. (ST novel: A Singular Destiny)
The Accords were dissolved, again, in 2399. This was due to the fact that the Federation strongly condemned the Klingon's attack on Gornar and ignoring the threat that Species 8472 truly brought to the Quadrants.(ST website: The Path to 2409) Though the Federation and the Klingons are now on talking terms again, the Accords have currently not been reinstated.
