The international community is strengthening counter-terrorism cooperation.
Tips
usage
反恐 is the short form of 反恐怖主义 (counter-terrorism). Like 反腐 (anti-corruption) and 反贪 (anti-graft), it's clipped news/government style — fine in headlines and policy contexts.
memory
反 'counter / oppose' + 恐 'fear / terror' → counter-terror. The Counter-Strike video game series is locally called 反恐精英 (Counter-Terror Elite).
