无异于

无异于 is bookish/formal — used in editorials, essays, and serious speech to deliver a strong rhetorical equivalence: action X is 'no different from' a more dramatic outcome Y. Compare colloquial 等于 (děngyú, 'equals to') and 跟...一样 (gēn...yīyàng, 'same as').

grammar

Structure: [subject/action] + 无异于 + [stronger comparison]. The 于 here is the classical preposition 'with respect to / from'. Literally 'have-no-difference-from'.
