Reps from the US are there almost every year.
Could be a number of things.
They could be there to talk about
The FED, Syria, Israel, Iran, trade tariffs, oil, etc.
They could be delivering a message.
It could be optics.
It could be intel gathering.
Their presence means very little, our current national stance as aimed at nationalism.
First time in decades.
I think it's a bit of all the above.
