Export Control pun, which refers to countries to which almost all exports, except humanitarian supplies, are prohibited, which typically means North Korea and a few other rogue states existing from time to time, as well as the sale of arms to countries subject to international arms embargoes.
Even at the height of Western Export Controls during the ‘Cold War,’ NATO allies did not regard the Soviet Union and Warsaw Pact as ‘beyond the river,’ that status being reserved for regimes considered to be complete international outlaws.
