I don't think his words elude to a specific previous agreement, but rather to the general concept that foreign emissaries (or ambassadors) are to be treated with respect. On earth, they often even get a form of legal immunity meaning they can't even be prosecuted for crimes. If he views himself as a representative of a foreign "state" (Zodiark) and we are representatives of the "state" he's visiting (Hydaelyn), than our drawing weapons on him would be a breech of standard diplomatic practices.
