North Korea is earning exceptionally high revenues, largely from war aid it provides to Russia, according to a report. These earnings are consolidating the power of the country's autocratic leader. The report adds that only a small number of people in North Korea are benefiting from an economic boom linked to this income. The findings suggest that the country's support for Russia's military efforts has become a major source of wealth, but that the gains are not widely shared. The report does not provide specific figures or name the leader. It describes the revenues as exceptionally high, particularly from war aid, and notes that the economic boom is strengthening the position of a small elite rather than the broader population.
