Bulgaria holds between 60 and 70% of the export of so-called "non-standard weapons" to NATO. These are weapons that are produced according to the standards of the former Warsaw Pact. These are major agreements that go through US companies and are approved by NATO. This was what lecturer at the Department of Journalism and Mass Communication at the University of California, Christopher Karadjov, told the BNR, on the occasion of the visit of Prime Minister Boyko Borisov to the United States at the invitation of President Donald Trump. The initially announced meeting topics did not include a comment on the future of Bulgarian exports of non-standard weapons to NATO. Much of it could not have been possible without US approval, he explained. Bulgarian exports of military products are worth about 1.2 billion euros a year, Karadjov pointed out.
