We swore neutrality to Aurvandil saying we would not aid either side of your war, we did not say we would remain neutral to any war in the west for one, and secondly, a nation has to actually act neutral to be neutral. If they aren't being neutral we are not the ones violating neutrality, they are.
I'm quite sure Rynn very clearly said "no interference in the wars in the west" in those exact terms.
