Approach based on the {\it qualitative} properties of the 't Hooft mechanism provides a unified description of available experimental data on $K$- and $ϕ$-meson production. Crucial tests for the hypothesized mechanism are suggested.LATEX, 10 pages, no figuresHigh Energy Physics - Phenomenology${\bar p} p$ Annihilation: Manifestations of Instanton Induced Quark Pair Production ?text
