Business Visa Exit re-entry

Hi,
I will be travelling to Riyadh from Manila with a 90-day multiple entry business visa, 30-days duration of stay. For the exit before the 30th day, does it need to return to the originating country (Philippines) or can I exit to other countries like UAE and return back to Riyadh? Thanks!

You just need to leave Saudi and return, it can be to any country and back to Saudi.

Any country you can enter with a Philippines Passport. You may want to consider Bahrain.
