Diplomacy is never “or”. It's always “and”. I have a range of tools that I can use. The mission here is one. The residence is another. Travelling is another. You choose which is most appropriate for the moment and for the occasion.
In the residence, it is more intimate. It is more secure. A lot of the people we entertain there appreciate the security of the residence. Larger events may be best held in the mission, but as I said, it's not one or the other.
