1963 Memorandum of Understanding On June 20, 1963, the United States and the Soviet Union signed the Memorandum of Understanding Between the United States of America and the Union of Soviet Socialist Republics regarding the Establishment of A Direct Communications Link, also known as the Hotline Agreement. This agreement should help speed up communication between the two governments and prevent the possibility of an accidental nuclear war. It is no coincidence that the agreement was reached only a few months after the Cuban missile crisis in October 1962, when the United States and the Soviet Union found themselves on the brink of nuclear conflict. The new agreement should avoid such a crisis in the future. In June 1963 negotiations on the ban on testing resumed with compromises from all sides. On 5 August 1963, the Nuclear Weapons Ban Treaty was signed in Moscow by US Secretary of State Dean Rusk (1909-1994), Soviet Foreign Minister Andrej Gromyko (1909-1989) and British Foreign Minister Alec Douglas-Home (1903-1995). France and China were invited to join the agreement, but refused. Nuclear Emergency Number Between the United States and China In April 1998, Chinese Secretary of State Tang Jiaxuan and U.S. Secretary of State Madeleine Albright signed an agreement to establish an emergency call number between the governments of the two countries. The hotline was activated during President Clinton`s visit to China in June 1998. Despite these liberal music reforms, many argue that Khrushchev`s arts legislation was not based enough on the freedom of expression of the Soviet people itself and too much on their personal tastes. After the emergence of unconventional and avant-garde music as a result of his reforms, Khrushchev gave a speech on 8 March 1963 that began to revisit some of his deinstalinization reforms, in which he declared: “We strongly reject this cacophonous music. Our people cannot use this waste as a tool for their ideology, and “society has the right to condemn works that go against people`s interests.”  Although the thaw was seen as a period of openness and liberalization, Khrushchev continued to restrict these newly acquired freedoms.
In the mid-1950s, discussions between the United States and the Soviet Union on a nuclear test ban began. Officials from both countries concluded that the nuclear arms race had reached a dangerous level. In addition, public protest against atmospheric testing of nuclear weapons has become increasingly strong. Nevertheless, discussions between the two nations (later Britain) continued for years and generally collapsed when the issue of revision was raised. The Americans and the British wanted inspections on the spot, which the Soviets strongly rejected. In 1960, the three sides seemed close to an agreement, but the bombing of an American spy plane over the Soviet Union in May of that year ended the negotiations. But despite the powerful role played by unofficial music in the Soviet Union during the thaw, much of the music composed during this period continued to be controlled. As a result, much of this unofficial music remains undocumented. Therefore, much of what we now know about unofficial music in the thaw can only be obtained through interviews with composers, performers and listeners who attended the unofficial music scene during the Thaws.  In 1956, an agreement was reached between the Soviet government and the U.S.
government to resume the publication and distribution of the American magazine produced in the United States in the Soviet Union and launch its counterpart, the magazine of the USSR in the United States.  In general, Khrushchev`s policy was inconsistent and questionable. The food crisis began as a result of experiments in agriculture.
