A few problems with this. That requires a world experienced in 2D, with one axis being towards or away from the centre, and the other being clockwise or anticlockwise. Works great when discussing intragalactic travel, but OP specified intergalactic travel. Where there is neither an obvious centre point nor a single plane on which things predominantly occur.
Though fwiw, language very similar to that is legitimately used in some real world languages. Some Malayo-Polynesian languages, such as Manam, talk about direction in terms of seaward, inland, clockwise, and anticlockwise.
The only country whose opinion should matter here is Taiwan. If and when they decide they want to be recognised officially, they should be. Not before, and not after.
