China has conducted all of its nuclear weapons tests at Lop Nur, and to date has tested a total of 45 nuclear weapons. 23 of these were atmospheric and 22 were underground. Their sizes range in yield from ~1 kiloton to ~4 megatons. China's most recent test was conducted on July 29, 1996 with a yield of ~1 to 5 kilotons.
