According to an opinion article from The New York Times, "After exercising restraint in its nuclear weapons program for decades, China has made the poor choice of upgrading its arsenal in a way that raises concerns about its intentions, introduces new uncertainty in Asia and could add more fuel to a regional arms race. The unsettling development is China's decision to equip its most powerful missile - the DF-5 for Dong Feng or East Wind, which can reach the United States - with multiple warheads instead of just one. The information was reported publicly for the first time earlier this month in the annual Pentagon report on China's military and security programs."
