WASHINGTON—China is expanding its nuclear force and is on pace to nearly quadruple the number of warheads it has by 2035, rapidly closing its gap with the United States, the Pentagon said in a report released Tuesday.
The report builds on the military’s warning last year that China is expanding its nuclear force much faster than U.S. officials had predicted, highlighting a broad and accelerating buildup of military muscle designed to enable Beijing to match or surpass U.S. global power by mid-century.
