China Steps Up Nuclear Arms Race

According to a major Chinese weapons research institute, China is aggressively developing its next generation of nuclear weapons, conducting an average of five tests a month to simulate nuclear blasts.
Its number of simulated tests has in recent years outpaced that of the United States. The US conducts them less than once a month on average.
Between September 2014 and last December, China carried out around 200 laboratory experiments to simulate the extreme physics of a nuclear blast.
