China quietly rebuilding secretive base for Nuclear-tests

A drilling rig recently bored a deep vertical shaft in the remote desert where China detonated its first atomic bomb. This evidence suggests that Beijing is considering testing a new generation of lethal nuclear arms. Waves of satellite images reveal that the military base at Lop Nur has newly drilled boreholes and other upgrades, indicating preparations for nuclear tests. Analysts warn that China's modernization of its nuclear establishment could spark an atomic rivalry and undermine the global test ban.
