China developed its first nuclear weapon in 1964; its nuclear stockpile increased until the early 1980s, when it stabilized at between 200 and 260. [1] India became a nuclear power in 1974, while Pakistan developed its first nuclear weapon in the 1980s. [1] [21] India and Pakistan currently have around one hundred nuclear weapons each. [19]
It took four years to complete. Being the sole site for nuclear testing in China for years to come, the Lop Nur test site underwent extensive expansion and is by far the world's largest nuclear weapons test site, covering around 100,000 square kilometers. [10] Sino-Soviet relations cooled during 1958 to 1959.
