The Soviets tested their first A-Bomb in 1949; one year before the start of the Korean War (1950-1953).
The first atomic bomb, developed by the Manhattan Project during World War II, was set off on July 16, 1945, in the New Mexico desert.
The atomic bomb was invented in 1933 by Leo Szilard, but it took the Manhattan Project (1942 to 1947) to actually build the first ones.
The first atomic bomb didn't explode in China, it exploded in New Mexico, USA July 25, 1945. I'm 95-99% sure New Mexico had the first one.
