nonintercourse, in international law, refusal of a state to engage in diplomatic or commercial relations with another state. It is a hostile act of retaliation for some wrong and is intended to effect redress. Since nations normally have diplomatic and commercial intercourse, nonintercourse may in some circumstances be a threat of war.
