How impoverished North Korea finances testing spree

North Korea’s recent barrage of missile tests, including Wednesday’s record of at least 23 launches, is raising an important question about its weapons program: How does the impoverished country pay for the seemingly endless tests?

While some experts say each North Korean launch could cost $2 million to $10 million, others say there is no way to estimate accurately given the North’s extremely secretive nature. They say North Korea likely manufactures weapons at a much cheaper cost than other countries because of free labor and possible clandestine Chinese and Russian support.
