在外交具体行动中依事件的严重程度，主要有：召回大使、降低外交级别、断交。而断交则属于外交具体行动中最严重的举动。如2012年九月，加拿大指责伊朗向叙利亚阿萨德政权提供军事援助，宣布断交。

In terms of practical diplomatic moves, according to how serious an incident is, the main ones are: recalling an ambassador, lowering an official's diplomatic rank and breaking off diplomatic ties. And breaking off diplomatic ties is the most serious among practical diplomatic moves. Like in September 2012, Canada criticized Iran for providing military aid to the Assad regime in Syria, and announced the breaking off of diplomatic ties.
