The correct answer to this open question is the following.
A relationship with another country based on less hostility is called "Détente."
This word has its origins in France and was applied to mean the diminish or release from tension. It was used during the Cold War years in which the Soviet Union and the United States competed in the arms race, the space race, and the spread/containment of Communism around the world.
Trying to ease tensions, on May 22, 1972, United States President Richard Nixon visited Moscow to have an official meeting with Soviet leader Leonid Brezhnev. In that visit, both leaders signed the famous SALT agreement: the Strategic Arms Limitation Talks.
