Nuclear weapons of China in the context of "Intercontinental ballistic missile"

Nuclear proliferation is the spread of nuclear weapons to additional countries, particularly those not recognized as nuclear-weapon states by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT. Nuclear proliferation occurs through the spread of fissile material, and the technology and capabilities needed to produce it and to design and manufacture nuclear weapons. In a modern context, it also includes the spread of nuclear weapons to non-state actors. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (including the so-called countervalue targeting of civilians), de-stabilize international relations, or infringe upon the principle of state sovereignty. Conversely, supporters of deterrence theory argue that controlled proliferation decreases conflict rates via nuclear peace.

Nuclear weapons were initially researched during World War II, jointly by the United States, United Kingdom and Canada, and separately by Germany, Japan, the Soviet Union, and France. The United States was the first and is the only country to have used a nuclear weapon in war, when it used two bombs against Japan in August 1945. After surrendering, Germany and Japan ceased to be involved in any nuclear weapon research. A nuclear arms race followed, with further countries developing and testing nuclear weapons. The US primarily competed with the Soviet Union, which carried out their first test in 1949. Seven other countries developed nuclear weapons during the Cold War. The UK and France, both NATO members, developed fission and fusion weapons throughout the 1950s, and 1960s, respectively. China developed both against the backdrop of the Sino-Soviet split.

The Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the Non-Proliferation Treaty or NPT, is an international treaty, the objective of which is to prevent the spread of nuclear weapons and weapons technology, to promote cooperation in the peaceful uses of nuclear energy, and to further the goal of achieving nuclear disarmament and general and complete disarmament. Between 1965 and 1968, the treaty was negotiated by the Eighteen Nation Committee on Disarmament, a United Nations-sponsored organization based in Geneva, Switzerland.

Opened for signature in 1968, the treaty entered into force in 1970. As required by the text, after twenty-five years, NPT parties met in May 1995 and agreed to extend the treaty indefinitely. The treaty defines nuclear-weapon states as those that have built and tested a nuclear explosive device before 1967; these are the United States (1945), Russia (1949), the United Kingdom (1952), France (1960), and China (1964).

The Force de dissuasion (French pronunciation: [fɔʁs də disɥazjɔ̃]; English: 'Deterrence Force'), known as the Force de frappe ([fɔʁs də fʁɑp]; 'Strike Force') prior to 1961, is the French nuclear deterrence force. The Force de dissuasion used to be a triad of air-, sea- and land-based nuclear weapons intended for deterrence. With the end of the Cold War, France decommissioned all its land-based nuclear missiles. The Force de dissuasion today is only an air- and sea-based arsenal. The French Nuclear Force, part of the French military, is the fourth largest nuclear-weapons force in the world, after the nuclear triads of the United States, the Russian Federation, and the People's Republic of China.

France's programme was shaped not only by the Cold War, but by the trauma that resulted from the Battle of France. General Pierre Marie Gallois, one of the architects of the deterrence force, is said to have been marked "by the tragic effects of an excess of German power" in his strategic thinking. France developed a military nuclear programme with the aim of retaining a strategic advantage over Germany. In 1961 Charles de Gaulle reminded John F. Kennedy that "Germany is legally prevented from having any [nuclear weapons]," adding that "the disadvantages deriving from German possession of atomic weapons would be far greater than the advantages."

The People's Republic of China has possessed nuclear weapons since the 1960s. It was the last to develop them of the five nuclear-weapon states recognized by the Nuclear Non-Proliferation Treaty (NPT). China acceded to the Biological Weapons Convention (BWC) in 1984, acceded to the NPT in 1992, and ratified the Chemical Weapons Convention (CWC) in 1997.

China tested its first nuclear bomb in 1964 and its first full-scale thermonuclear bomb in 1967. It carried out 45 nuclear tests before signing the Comprehensive Nuclear-Test-Ban Treaty in 1996.
