Russian Foreign Minister Sergei Lavrov gave a speech.
Tips
culture
Not a specific person but a transliteration of the Russian male name Сергей (Sergei). In Chinese news the name attaches to many individuals — Lavrov, Shoigu, Prokofiev, Rachmaninoff — so it's best treated as a name element rather than a single referent.
usage
When transliterating foreign names, Chinese uses a fixed set of 'name characters' (谢, 尔, 盖) chosen more for sound than meaning. Ending in -盖 or -夫 is a strong visual cue that you're reading a Russian name.
