Here's the exchange:
Ban: Can you just wrap up please.
Al-Moallem: I came here after 12 hours in the airplane, I have few more minutes to end my speech. This is Syria.
Ban: How much do you have left now?
Al-Moallem: I think 5-10 minutes.
Ban: No, no. I will give you another opportunity to speak.
Al-Moallem: No, I cannot divide my speech. I must continue ... I will do my best to be fast.
Ban: Can you just wrap up in one or two minutes?
Al-Moallem: No, I can't promise you, I must finish my speech. ... You live in New York, I live in Syria. I have the right to give the Syrian version here in this forum. After three years of suffering, this is my right.
Ban: We have to have some constructive and harmonious dialogue, please refrain from inflammatory rhetoric.
Al-Moallem: It is constructive, I promise you, let me finish.
Ban: Within 2-3 minutes please, I will give you another opportunity.
Al-Moallem: You spoke for 25 minutes, at least I need to speak 30 minutes.
Few minutes later, Ban interrupts again. Al-Moallem says he has one sentence left, to which Ban asks him to keep his promise.
"Syria always keeps its promises," al-Moallem replied, triggering approving laughter from the Syrian government delegation behind him and a wry grin from Ban.
