North Korea may have spent as much as $642 million on its nuclear programme last year, according to anti-nuclear activists, as the impoverished country appears ready to test a new weapon despite battling a COVID-19 outbreak and economic crisis.
There is no confirmed data on North Korea's nuclear spending, or the size of its arsenal. Since 2006 it has conducted at least six nuclear tests, and appears to be preparing to resume testing for the first time since 2017.
